INSTALLATION, OPERATION, LUBRICATION, MAINTENANCE AND STORAGE INSTRUCTIONS SAFETY Electrical power or engine must be shut off completely before attempting service on the pump or its drive. Air surrounding the unit to be free of toxic, flammable, or explosive gases. Tools needed should be planned for in advance (see valve seat pulling instructions) and should be clean and of adequate size. A torque-wrench will be required to tighten connecting rod cap screws. A properly sized and set relief valve installed in the pump discharge system (ahead of any block valves) is necessary to protect personnel and to avoid dangerous overpressure. The relief valve set pressure should be not more than 25% above the design operating pressure and should discharge to tank or to the atmosphere (toward the ground) and must not be directed back to the pump suction system. WARNING: Improper use of this equipment could result in loss of life. CALIFORNIA PROPOSITION 65 WARNING: WARNING: This product and related accessories contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. STORAGE Pumps are shipped dry from the factory. If a pump has been in storage in a humid environment for more than 6 months the crankcase cover should be removed and carefully examined for rust or water collected in the power end. Flush out any evidence of rust or damage that exists, using a light clean oil. Pumps to be placed in extended storage should be cleaned, repaired as needed and completely filled to the top with clean oil to prevent rusting. Rotate pump monthly 4-1/2 revolutions. Plug all openings to prevent air entry and oil leakage. Fluid ends must be completely drained of water and suction and discharge ports blanked off. Store pump in a clean, dry location. PUMP LOCATION AND PIPING DESIGN Locate pump and driver in a clean, well-drained, ventilated and brightly illuminated area with adequate working spaces around the pump to provide ample access to fluid end, power end and associated drive elements. Do not expect good maintenance to result if the pump is positioned on muddy terrain or in a dirty, cramped, dimly lighted area. The supply tank(s) should be large to allow dissolved air and other gases to escape from the liquid and allow suspended solids to settle out before entering pump. A system employing dams and settling chambers is desirable. Pumps are not designed to withstand piping weight, vibration and the effects of thermal piping expansion/ contraction. Piping loads may be considerable and the weight of all valving, dampeners, filters and associated forces, moments and couples must be completely iso lated. Use flexible hoses and rigid piping supports to isolate the pump and its driver from these effects. SUCTION PIPING No part of the piping system deserves more careful planning than the suction piping system. Suction piping must be short, direct and oversize. Use one pipe size larger than the pump suction connection. For example, since the suction connection for the MA-300L pump is 8", use a 10" short, direct suction line from the tank to this pump. The shorter it is, the better. 1 to 3 feet per second suction velocity is acceptable. Use no elbows, tees, or restricted port valves in this line. Do not install orifice plates or positive displacement type fluid meters in the suction line which act as flow restrictors. Avoid the use of suction filters, if possible. Consider filtering the liquid as it enters the supply tank rather than as it leaves it. The use of an eccentric reducer with the flat side up located at the pump suction connec tion is recommended. The suction line should slightly rise from tank to pump and loops in which air may collect must be avoided. The absolute pressure in a suction line may be less than atmospheric pressure and air may be sucked into the line unless all flanges and connections are airtight and watertight. If you can see water leaking out of a suction line when the pump is still, that may mean air is being sucked in when the pump is running. Suction piping should be buried beneath the frost line or insulated to avoid freezing in the winter. If the suction line has a block valve at the supply tank, a suitable relief valve is suggested to relieve the suction piping from any possible dangerous overpressure from the discharge piping system. Suction piping is often large, heavy (especially when filled with liquid) and tends to vibrate. Proper solid supports are recommended. A suction hose located near the pump will isolate these effects, protecting the pump from the forces and moments that piping weight creates. New suction piping systems should be flushed free of pipe scale, welding slag and dirt before starting the pump.

Hydrostatic testing to detect air leaks is advisable. Proper choice of suction hose construction is essential to avoid collapse of the hose liner. Install a dry type compound gauge in the suction line near the pumps which should fluctuate evenly. If violently pulsating, this gauge indicates that the pump is not fully primed or that one or more valves are inoperative. ACCELERATION HEAD A characteristic of all reciprocating pumps is the imperative need to consider the effects of acceleration head which is a system related phenomenon. Acceleration head may be considered to be the loss of available hydraulic head (energy) in the piping system occurring because the demand by the pump cylinders for liquid is not smooth and even. Because the pump’s demand for liquid is cyclical, the velocity of the liquid in the entire suction system is not truly constant but varies in response to the combined demand of the reciprocating plungers. Thus, liquid in the suction system is compelled to be accelerated and decelerated several times during each crankshaft revolution, depending on the number of plung ers. Called “acceleration” head, this loss of available hydraulic head is proportional to: (a) The speed (RPM) of the crankshaft (b) The average liquid velocity in the piping (c) The length of the suction piping (d) The number of pumping chambers (triplex, etc.) (e) The compressibility of the liquid Thus, for a given pump, acceleration head effects may be reduced by the use of the shortest possible suction line, sized to reduce liquid velocity to a very low speed. This is often more economical than the use of charge pumps or expensive suction stabilizers. NOTE: Charge pumps should be sized to 150% of rated pump volume. Charge pumps need to be centrifugals, not a positive displacement pump. A charging pump is usually not a good substitute for a short, direct, oversize suction line, nor is it a substitute for the computation of available NPSH, acceleration head, friction head, vapor pressure and submergence effects duly considered. Required NPSHR of Myers Aplex Series pumps depends on speed, choice of plunger size and valve spring type. Consult Myers Aplex Series Engineering for help with your particular application. A full discussion of suction system losses is given in the Standards of the Hydraulic Institute, 14th Edition. A common design mistake is the connecting of two (or more) reciprocating pumps to a common suction header. This is a profoundly complicated suction system, largely not amenable to mathematical analysis, and is frequently the cause of severe pump pounding, vibration and early valve failures. Each pump should be fed by its own separate, individual piping system, free from the effects of other pump cyclical demands for liquid. DISCHARGE PIPING A properly designed discharge piping system usually prevents the need of a pulsation dampener. The most common mistakes made in the design of the discharge piping system are: 1. Pumping directly into a tee or header. A standing wave (either audible or subaudible) then often occurs. If flow must enter a header, use a 45º branch lateral (or equivalent) to avoid a reflecting surface from which sound can reflect. 2. Pumping into short radius 90º elbows. Instead, use two 45º elbows spaced 10 or more pipe diameters apart. 3. Pumping into a right angle choke valve. 4. Pumping into too small piping line size. Piping should be sized to keep fluid velocity below 15 feet per second, max. 5. Pumping through an orifice plate, small venturi, or reduced port regular opening valve. 6. Pumping through a quick closing valve, which can cause hydraulic shock (water-hammer). A good discharge piping system includes: 1. A properly sized, correctly set relief valve. Discharge from relief valve returned to tank (not to pump suction). 2. A full opening discharge gate or ball valve. Avoid restricting plug valves, globe valves and angle valves. 3. A pressure gauge with gage dampener or snubber. Consider a liquid filled gauge. (Scale range to be double the normal pump operating pressure.) Locate the relief valve and pressure gauge ahead of any block valve and so that the pressure in the pump is always reflected at the relief valve. The relieving capacity of the relief valve must exceed the capacity of the pump to avoid excessive pressure while relieving. Use a full size relief line. To minimize vibration (whether hydraulic or mechanical), discharge lines should be kept short, direct, well supported and solidly anchored. Avoid dead ends and abrupt direction changes. BYPASS PIPING Some designers ignore this important aspect of proper design of pump piping systems. A reciprocating pump, especially after maintenance of the valves or plungers, starts with one or more fluid chambers

full of air. Pumps operating on propane, butane, or other volatile liquids start with vapor in the fluid chamber(s). Positive displacement pumps do not automatically purge themselves of air and gas after shutdown. For example, a quintuplex plunger pump will, after servicing, expel the air in four of the five pump chambers. Thus, the pressure from four of the active cylinders will keep shut the discharge valve of the inactive, or air bound, cylinder. Then, the air or gas in this cylinder will be compressed and expanded by its reciprocating plunger and never leave the chamber. Similar effects occur in duplex and triplex pumps. To overcome these difficulties, adequate provision for expelling the gas in the air bound cylinders must be present. Common practice is to totally relieve the pump of all discharge pressure during the start-up, after servicing. Consider the operational advantage of a full-sized bypass line (return to tank) which substantially removes discharge pressure from all cylinders during the start. This requires a block valve on the discharge side and a full opening bypass valve on the other side. For economy, the bypass (to tank) can be combined with the relief valve discharge line. This line must be full-sized, well supported, and sloped downward to avoid freezing in cold weather. (A frozen relief valve change the oil every 1,500 hours or sooner if it becomes contaminated with water or dirt. Fill to the center of the sight gauge. Recheck after starting, adding oil to center of gauge while running. V-BELT DRIVE A properly designed, well-aligned V-belt will provide years of reliable, economical service if properly tensioned and kept dry, free of oil and ventilated. Alignment is critical for long life. If the shaft axes are not truly parallel, or if the sheave grooves are not positioned in good alignment, some belts will carry most of the load, resulting in their disproportionate load share and may actually twist or turn over in the groove. Use a straight edge across the rim of the sheaves to detect and correct for misalignment. After about one week of operation, new V-belts will have stretched somewhat. The motor must be moved on its slide base to re-establish proper belt tensioning. Insufficient tension results in slippage, burning, squealing (especially during starting) and shortened belt life. Overtightening imposes excessive loads on pump and motor bearings and can cause early shaft fatigue failure. Use the following table in adjusting V-belt tension:

The ability of a reciprocating pump to be self-priming depends on the ratio of the swept (displaced) volume in the cylinder to the unswept (clearance) volume at the end of the stroke. This depends on the design of the fluid end and on the plunger size selected. Choice of the largest size plunger for a particular fluid end improves this compression ratio and so leads to self “B” 5 – 6 3-1/4 – 5 “C” 9-3/4 – 13 6-1/2 – 9-3/4 “3V” 4 – 10 3 – 7-1/2 “5V” 17 – 30 13 – 23 Applying the above forces with a small spring scale, adjust motor position to provide the following deflection at mid-span:

pumps that require frequent servicing, or which handle volatile liquids, or which contain substantial amounts of dissolved air or gas. An automatic bypass and purging system for these applications may be merited. LUBRICATION Myers Aplex Series pumps use 62 quarts of S.A.E. 40 wt. nondetergent oil in the crankcase. This oil requires only a nonfoaming additive and should possess good water separation (antiemulsion) characteristics. Such oils are often labeled industrial or turbine quality lubricants. If these oils are not available, a good quality gear oil or EP oil may be substituted. See lubrication guidelines. In temperate climates, oil viscosity selected should fall between 70 and 84 seconds Saybolt viscosimeter at 210º F. In arctic service, low pour point oils are needed. After the first 500 hours of operation in a new pump, drain the oil. Refill with clean, fresh oil. Thereafter, 16 1/4 22 3/8 28 7/16 32 1/2 40 5/8 48 3/4 60 15/16 Belts must be matched in pitch length. If one or two belts are slack, when the others are correctly tensioned, investigate for possible reasons. Correct any misalignment or lack of matching so each belt will transmit its load share.

C.D. Sheaves must be balanced to prevent abnormal vibration. Balancing weights must not be removed. Type “QD” sheaves must be evenly tightened on their tapered hubs to avoid rim wobble and severe lateral vibration. V-belts that snap and jerk will produce abnormal vibration and loads on both pump and motor or engine. Run the pump several minutes at full load with belt guard removed, observing for uneven motion on the belt slack side, especially. When an old V-belt drive becomes unserviceable, replace all belts, not just the broken or cracked belts. Do not operate belts on sheaves having worn, rusted, greasy or broken grooves. Shut off power to driver before servicing drive or pump. WARNING: Do not operate without appropriate guards in place. DIRECTION OF ROTATION Before placing pump in operation, check that crankshaft rotation agrees with the arrows cast on top of the power frame by briefly jogging the electric motor. Crankshaft rotation must be clockwise as viewed from the right side of pump. If pump is gear driven, remember that the pinion shaft turns opposite the crankshaft, if using a single-reduction geared drive or in the same direction as the crankshaft when using a planetary gear. AUTOMATIC (SAFETY) SHUTDOWNS Carefully check all electric shutdown devices present, such as crankcase oil level, discharge pressure, vibration, lubricator oil level, motor thermostat, etc. CRANKSHAFT ASSEMBLY GENERAL Myers Aplex Series crankshaft suspension uses two single row tapered bearings, which are shim adjusted to provide the correct running clearance. Thorough cleaning of all components prior to assembly is essential. Power frame, shaft, bearings and retainer must be scrupulously scrubbed with clean solvent (such as kerosene) before starting. Remove any oil, dirt, rust and foreign matter which might prevent the correct fit up. Crankshaft journals are critical. Remove all burrs, rust spots, and nicks, paying special attention to the ground areas on which bearings and oil seals operate. Connecting rods and crossheads must be previously installed into MA-300 pumps before the crankshaft assembly. TAPERED ROLLER BEARINGS Shaft and frame tolerances provide a tight (press) fit on the shaft and tap fit in the frame. The best way to install the cone assembly (consisting of the inner race, cage and rollers) on the shaft is to heat the cone assembly in an electric oven for 30 minutes at 300 to 400ºF. (Do not heat bearings with an acetylene torch. This ruins the bearings.) Using clean, insulated gloves, remove the hot cone assembly from the oven, promptly dropping it on to the shaft. The cone assembly must contact the seat thrust face (not be cocked) and the large end of the rollers must be down. Do not hammer on the bearing. The soft steel cage is easily distorted, ruining its function as a roller separator and guide against skewing. If the cone does not contact its thrust face properly, it must be pressed into place using a specially machined sleeve (which does not touch the soft steel cage). A hydraulic press is recommended if this difficulty arises.

CUP INSTALLATION Tapered roller bearing cup (outer races) is a press-fit in the bearing carrier, using a hydraulic press. Cup must be pressed into a clean carrier until the race solidly abuts its shoulder (must not be cocked). The tool or plate used for this must contact only the outer end face – not on the taper. CENTER BEARINGS The two center bearings are pressed into the power frame bore, one from the right and one from the left. The drilled indentation on the bearing must be aligned with drilled and tapped hole in the back of the power frame. After the bearing is pressed into place, this indentation must approximately line up to allow usage of the locking set screw. Press into place until the flange on the bearing faces out on the counter bore in the power frame. This ensures the bearing is not cocked. After the bearings are in place, lock them with the set screw. INSTALLING CRANKSHAFT SHIM ADJUSTMENT OF TAPERED ROLLER BEARINGS To provide for crankshaft thermal expansion, sufficient shims must be installed to provide .005" to .015" lateral end play, when shaft is cold. Shims must be placed only under the drive side bearing carrier. The lube oil housing has a gasket under it. A feeler gauge and a 1" micrometer caliper are required. Install a trail shim set on one side of the pump. Tighten the flange bolts on this side only. CAUTION: Lubricate the frame bores and the O-ring seals located in each carrier to prevent damage during entry. Oil the bearings. Draw up the carrier, evenly tightening its cap screws. Rotate the crankshaft slowly by hand, seating all rollers into running position. Measure the gap existing between the frame face and carrier flange. The correct thickness of the shim set to be installed equals the measure gap plus about .010". After installing above shim set, a dial indicator may be used against the end of the shaft to confirm the shim selection. Bump the shaft in one direction and zero the dial indicator. Bump the shaft the opposite way. If shimming is correct, the shaft will move laterally from .005" to .010". The recommended tightening torque for bearing retainer 3/4 – 10UNC cap screws is 211 to 257 ft. lbs. INSTALLATION OF CRANKSHAFT OIL SEAL Insert oil seal over the end of crankshaft and position it into the oil seal bore in the power frame or bearing retainer. Using a rubber mallet, tap it into the bore until the face of the seal is flush with the power frame or bearing retainer. LUBE OIL PUMP ASSEMBLY Lube oil pump and filter assemblies are employed in certain Myers Aplex Series pumps. This assembly is installed after the shaft and its tapered bearings have been correctly set. Providing filtered oil under pressure (35 to 75 psi) to all crosshead pin bushings and crankpin bearings, this special gear pump is driven by a bolted – on drive shaft. Driver is made with a female drive square which drives the male square end of the lube oil pump shaft. The driver shaft is piloted by the main bearing inner race cone and is secured to the crankshaft by four socket head cap screws. Stake their heads using a center punch to upset the adjoining metal. The lube oil pump (Tuthill) is a gear type pump possessing a self-reversing sector which automatically switches suction and discharge connections in the event (not recommended) that the pump is caused to rotate opposite the correct direction. The lube oil pump is readily removed for inspection, repair, or replacement without disturbing any other pump component. The lube oil pump shaft is journaled in a bronze bushing fitted into the bearing carrier. If this bushing becomes worn (check for contaminated crankcase oil), it must be promptly replaced. A worn bronze bushing will cause this pump to frequently lose its prime, and also may cause excessive wear in the pump rotor teeth. DISASSEMBLY After removing the connecting rod cap and cap bolts (note identifying marks on each cap so each may be later correctly reassembled onto its own rod), remove a bearing carrier from the frame. Two jack out tapped holes are provided in the flange of the carrier for this purpose. Support the shaft during removal to avoid damage.

12

The crankshaft may now be extracted, once all connecting rods are moved clear. Examine the crankpin surfaces for wear or corrosive pitting. The correct diameters of these journals are: Crankpin Diameter............4.5000/4.4990" If worn more than .010" undersize, crankshaft should be replaced, or an attempt to salvage it may be made at a shop well equipped to grind the crankpins which must be fully round, chrome-plated, and finish ground to the above sizes. (Myers Aplex Series does not perform this function.) Crankshaft tapered roller bearings should be carefully examined for pitting, scoring or corrosion, and replaced as required. The cone and roller assembly is most easily removed by first cutting away the cage using an acetylene cutting torch. Then heat the cone (inner race) with the shaft held vertically so cone will drop off due to its own weight. Avoid excessive heat on the crankshaft which tends to distort its geometry. Cups (outer races) of tapered roller bearings may be extracted from bearing carrier using a conventional bearing puller tool of the automotive type (widely available). Do not attempt to use heat on a bearing carrier as this will result in severe distortion (out-of-round). Replace the bearing carrier if broken or out-of-round. CONNECTING ROD, CROSSHEAD, EXTENSION ROD, CROSSHEAD PIN and WIPER BOX ASSEMBLY and DISASSEMBLY: HALF CRANKPIN ROD GENERAL Myers Aplex Series connecting rod assemblies employ precision automotive type steel backed, babbitt-lined crankpin bearing halves which require no shims for clearance adjustment. This pump employs full circle (piston type) crossheads, and hardened stainless steel extension rods, which are field replaceable. Extension rods are provided with a wrenching flats to permit tightening of the tapered thread into the crosshead, establishing accurate alignment while affording easy field installation. Before beginning the assembly all parts must be scrupulously cleaned, removing all oil, dirt, rust, and foreign matter which prevent proper fitting, or which might tend to score the rubbing surfaces. Clean and examine the power frame bores for scoring and abnormal wear, especially wear of the lower crosshead guide way. Hone smooth, if rough. Measure the bores of the frame using inside micrometers to determine abnormal frame wear if any. New Crosshead O.D. New Frame Bores 6.740/6.737" 6.749/6.752" Frame bores which have become worn more than .015" must be sleeved with a cast iron liner to re-establish correct geometry and alignment. Contact Myers Aplex Series concerning the repair of badly worn frame bores. Smooth any rough corners and edges on the crosshead skirts, using fine emery cloth. Examine and clean the female tapered threads and wrist pin holes. INSTALLING WRIST PIN BUSHINGS

After applying oil to the bushing O.D., use a hydraulic press to force home. Repeat this procedure for the second bushing. When a bronze bushing is pressed into place, the I.D. (bore) of the bushing is reduced somewhat, owing to the extent of press fit. Therefore, a clean, new wrist pin should be inserted into the bushing bore to establish that running clearance has been obtained. The running clearance between the wrist pin and installed bushing is: New pin O.D. Installed bushing bore Oil Clearance 2.6875/2.6860" 2.6895/2.6905" .0020/.0045" Replacement bushings are furnished prebored by Myers Aplex Series which usually eliminates the need to ream the installed bushing bore. However, due to slight variations in finishes and tolerances it sometimes happens that more than predicted contraction of the I.D. occurs. This occurrence results in a slight interference which may be eliminated by lightly honing the bore of the bronze (not by reducing the pin size). An automotive engine repair shop usually is equipped with power honing machines capable of smoothly finishing the bushing bore. Bore of bushing must be round and free of taper. BOLTING THE WRIST PIN Install two set screws in the wrist pin, one at each end, then bolt the wrist pin to the connecting rod. Place the connecting rod inside the crosshead and slide the wrist pin through the crosshead and connecting rod. The hole in the wrist pin should line up with the hole in the connecting rod. Install the shoulder bolt through the wrist pin and thread into connecting rod. Torque to 25 ft. lbs.

(Myers Aplex Series does not offer this service.) Connecting rod/cap bore must be perfectly round and within above sizes and free of taper. Discard, if elliptical or tapered as the result of abnormal heating. Each cap and rod is match-marked for correct identification. Take care that each cap is reinstalled properly with its companion rod. Bearing halves are identical and are prevented from rotating by tongues which fit into slots in the cap. Check that all oil holes are clean and fully open. Grit is the greatest enemy of bearings, however precisely manu factured. Hence, all surfaces must be perfectly clean and lightly oiled prior to assembly. Remove any burrs or sharp corners which prevent the perfect fitting of these precision bearings. Using a torque wrench, tighten cap bolts as follows: Thread Size Tightening Torque 5/8"-18UNF 125–135 ft. lb. Specified torque, applied to clean, well-oiled threads and bearing faces, will create tensile stresses in the cap bolts from 90,000 to 110,000 psi, approx. and will provide correct initial tension. Myers Aplex Series pumps use high strength cap bolts suitable for these initial load ings, maintained by using safety wire to maintain the

After all rods and caps are secured, slowly turn the crank shaft to be sure no bearing is in a bind. Using a flashlight, examine the location of each connecting rod (eye end) within its crosshead. Rods must not touch any crosshead boss or skirt.

WIPER BOX ASSEMBLY GENERAL Extension rod wiper boxes (sometimes referred to as the diaphragm stuffing box, or stripper housing assembly) serve two important functions: retention of crankcase oil in the power end and exclusion of dirt and water. Myers Aplex Series has developed a unique sealing set which operates on a hardened and ground stainless steel flats entering first. Do not force. The sharp corners on the wrenching flats may damage the seal lips (resulting in oil leakage). EXTENSION ROD WRENCHING FLATS

extension rod (often called “pony” rod), and a metal baffle disc affording protection against leaking plunger packing. The seals require no adjustment, only correct and careful assembly. WIPER BOX TAPERED THREADS

DOUBLE-LIPPED WIPER SEAL This seal keeps oil from leaking out of the power frame. Developed by the Parker Seal Group, this double lipped wiper provides an additional beveled sealing lip, yielding excellent film-breaking and the driest rod sealing available. With extension rod inserted through the wiper box seal, thread the tapered threads (must be clean) into the tapered crosshead female threads. Firmly tighten, apply torque to the wrenching flats only. Never damage the extension rod ground surface. Then fasten the wiper box to the power frame by tightening the cap screws. Oil leakage between frame face

The double-lipped wiper seal is inserted into its counter bore with its lips directed toward the oil in the crankcase. (Will not work if installed backward.) DOUBLE-LIP CANNED WIPER The double-lip canned wiper oil seal is to keep contamination out of the power frame. This seals press fit installation prevents O.D. contamination while the additional seal lip works in conjunction with Parker rod seals to provide sealing for leakage. An aggressive wiping lip, facing the element, ensures contaminant exclusion along the rod. PRESS WIPER BOX SUPPORT INSERTING THE EXTENSION ROD Insert the extension rod through the wiper seals with the tapered thread end entering first. Care should be used in moving the extension rod through the seals with wrenching DISASSEMBLY/ASSEMBLY When removing fluid end, pump several gallons of clean water through before service is performed to remove contamination left behind. Inspect fluid end for stress cracks to determine if replacement is necessary. Inspect and clean all openings for contamination. Disconnect suction/discharge piping before disassembling the fluid end. Remove the stuffing boxes and nuts between the fluid and power end. Support the fluid end while sliding the assembly away from the power frame. Reverse procedure to reassemble and torque all fluid end nuts to 1300 ft. lbs.

STUFFING BOX, PACKING AND PLUNGER ASSEMBLIES GENERAL Myers Aplex Series pumps all feature field removable and replaceable stuffing boxes with plungers separable from the extension rods. If desired, the boxes, plungers, and packing units may be installed (or removed) as a unit assembly, permitting service outside the pump. All boxes are retained by four studs and nuts, and are centered in the frame bore, ensuring correct alignment. The plungers may also be removed separately (without box removal) to facilitate repacking. With this option, the necessary space required to remove plunger, it is first necessary to remove the extension rod. SPRING LOADED PACKING Compression Packing SPRING GUIDE SPACERS GLAND RING PACKING SPRING GLAND RING SPRING GUIDE Chevron Packing Note that the gland is screwed tightly onto the box and contacts its face. The spring is providing all of the initial compression and adjustment. No adjustment is provided by the gland. Since the force exerted by the spring is contingent on the space provided for it, the correct lengths of all rings is essential for good tensioning. Spring: A stiff Inconel® spring, which closely fits the bore of the stuffing box, is used in this assembly. This spring is compressed in a vise to the operating length required plus 0.25" and tied with waxed nylon spot tie cord. The cord is looped over the ends of the spring through the coils and tied to maintain the length mentioned above. Each spring is assembled into the stuffing box. Note that the spring does not contact the plunger. Spring-Guide Ring: Plungers are heavy and the importance of a well-fitted guide ring which carries this weight is often overlooked. Discard any guide ring that becomes worn or scored, as it will then not serve its purpose. It should fit snugly in the box. Apply oil generously to this ring. Spring Loaded Packing: Three rings of chevron or compression packing are installed next. For compression packing, install them with the skive intersections 180º apart to discourage leaking. Gland Ring: This ring also fits the plunger and helps support the plunger weight. Discard it if bore is worn, rough or out of-round. Lightly oil the ring before insertion. The gland ring fits all packing. J-STYLE STUFFING BOX and PLUNGER ASSEMBLY (STYLES 838 & 858) GLAND RING PACKING SET THROAT BUSHING PRESSURE BAFFLE LANTERN RING The above depicts Style 838 and 858 packing correctly installed with all packing lips facing toward the fluid pressure. Note that two units of Style 838 and 858 packing are positioned ahead of the lantern ring, and one unit is positioned behind it. Thus lubricant entering the lantern ring is forced toward the pressure. Throat Bushing: Plungers are heavy and the importance of a well fitted throat bushing which carries this weight is often over looked. Discard any throat bushing that becomes worn or scored, as it will not then serve its purpose. It should fit snugly in the bottom of the box. Apply oil generously to this ring. Style 838 and 858 Packing: Developed by Utex Industries, Inc. Style 838 and 858 packing is a non-adjustable type packing which depends solely on hydraulic pressure to energize the sealing lips. (Gland-tightening forces do not energize the lips.) Tightening and hydraulic end thrust loads are transmitted entirely through the center support portions of each ring.

16

The flattened portions of the rings are large enough to withstand overtightening. Do not attempt to adjust this type packing. It should be kept thoroughly tightened at all times. Running it loose will not usually cause it to drip at all. But it can ruin the box in time. Lightly oil each ring and the box bore and then lightly tap in each ring separately with the rings facing correctly. This is most easily done before installing the plunger. Lantern rings are provided with O.D. and I.D. reliefs and two (or more) oil holes to allow lubricant to reach the plunger. After the last unit of Style 838 and 858 packing is in place, generously oil the lips of all seal rings to ease plunger entry. SEAL RING TOP ADAPTER (HARD PHENOLIC) BOTTOM ADAPTER (HARD PHENOLIC) PRESSURE INSTALLING THE GLAND Considerable downward pressure on the gland is required to compress the spring and to move the packing into location, and to start the threads of the box. Once the gland threads are started, screw it down completely until it makes up tightly against the face of the box for spring loaded packing. For J-Style or gland adjusted packing, tighten the gland until it is seated firmly against the packing. INSTALLING THE STUFFING BOX Myers Aplex Series stuffing boxes derive their alignment from the bores of the power frame and the faces of the fluid end, so these surfaces must be cleaned of rust, scale and dirt before assembly is begun. Wash all contacting surfaces with clean solvent and dry with a clean shop towel. A nitrile rubber seal is used to seal between the face of the fluid end (must be flat, clean and smooth) and the face of the box. Replace if damaged. All stuffing boxes are retained by four large studs and nuts which extend through the power end, serving to clamp the box and the power frame tightly against the fluid end face. These four stud nuts must be evenly tightened. JACKSCREW HOLES FOR BOX REMOVAL

4 1 INSERTING THE PLUNGER Apply oil liberally to plunger O.D. and lightly tap it through the packing. When introducing the plunger through the MA-300 stuffing boxes, also apply oil liberally

to the O.D. of each integral extension rod to allow easy passage through the wiper box seals. TAP HERE USING RUBBER MALLET OILED PLUNGER GLAND RING STUFFING BOX BENCH TOP A soft rubber mallet is recommended to avoid any damage to the plunger face or its threads. Remember: The fragile nature of packing rings and plunger surfaces deserves your respect and avoidance of careless damage to these key elements. 3 2 Using a socket, socket extension, and torque wrench, tighten clean, well-oiled threads and nut faces. Stud Threads Tightening Torque 1-1/4"-8UN 725–775 ft.lb. CONNECTING THE PLUNGER Install the metal baffle plate on the extension rod, roll the pump slowly until the extension rod male threads just touch the mating plunger female threads. Applying a pipe wrench to plunger knurled area, thoroughly tighten the connection. Do not use a cheater when connecting plunger to extension rod.

PACKING Packing life for aramid fiber packing may be improved in some applications by regular, systematic lubrication. An optional force feed lubricator assembly is often recommended especially for pumps on continuous duty. This provides regular, controlled supply of lubricant lowering friction and heat. Additionally, the regular application of the correct lubricant aids dissolving of salt and gyp tending to build up on the plungers in produced water applications. For this service, Rock Drill Lubricant is a popular and effective packing lubricant. Plungers in CO2, ethane, or other very cold liquid services may use brake fluid. This fluid does not congeal into a solid that cannot enter the packing. Consider the use of an air-sealed cradle into which dry (instrument) air may be directed, excluding the moisture, which causes plunger icing especially in very humid conditions. Packing lubricant for pumps on light hydrocarbons, hot water, lean oil, naphtha, or gasoline often requires experimentation. A good start is to use steam cylinder oil. Castor oil is sometimes successful as a packing lubrication for liquid propane and butane services, at ambient temperature. In pumps placed in arctic service, a special low pour point oil is indicated. Packing lubrication is not permitted on some services, such an amine, food stuffs, etc., and other packing styles and materials may be required. PLUNGERS Myers Aplex Series offers its own unique product: the Myers Aplex Series Rokide® plunger. This premier quality plunger consists of a chromium oxide deposition on a solid stainless steel body. Ordinary handling will not damage this fine product. Avoid striking the coated surface (black) during installation. Apply light forces only on the ends of the plunger. Do not hammer or pry. All threads on Myers Aplex Series plungers must be cleaned and oiled before assembly. Stainless steel (although very corrosion resistant) has a tendency to gall and seize. To avoid this, an anti-seizing lubricant is well worth its use. Apply oil to the threads and the rubbing surface. Myers Aplex Series can supply solid ceramic plungers on order. This plunger is very fragile, vulnerable to thermal and mechanical shock, and must be handled with the greatest care. Use only a rubber mallet to insert it into the packing. Other plunger types are available upon request. DISC VALVE SYSTEMS AND ABRASION RESISTANT GENERAL Myers Aplex Series has developed a unique setting/ puller system permitting quick, easy and safe methods of installing and removing tapered seat valves. The system allows servicing without distortion of the seat, with minimum effort and no damage to fluid end tapers or seat. DISC VALVE and ABRASION RESISTANT VALVE CONSTRUCTION LOCK NUT SPRING RETAINER SPRING VALVE DISC VALVE STEM PULLING THREADS VALVE SEAT VALVE SPRING GUIDE CAGE POLYURETHANE INSERT VALVE BODY VALVE SEAT The Myers Aplex Series valve is a precision made subassembly using threads cut into the rim of seat for use with Myers Aplex Series setting/pulling tool. These threads do not deteriorate as proved by field experience. By locating these on the rim, setting/pulling forces are now applied only to the rim of the seat, never to the webs (or spokes), or to the center section. Distortion of the seat is eliminated. Access to these seat threads is provided by the removal of the valve cage on abrasion resistant valves or the spring retainer on disc valves, which is screwed onto the seat. An anti-seizing lubricant applied to all threads is good insurance against future difficulty.

18

SETTING THE VALVE SEAT Effective pressure-sealing between tapered (male) seat and tapered (female) fluid end deck is possible only if the tapers are absolutely clean and dry just prior to installation. Thoroughly clean surfaces using a clean solvent. Dry with a clean shop towel. Examine the cleaned fluid end deck tapers, using a flashlight, and remove all deposits of gyp, salt, or other encrustation. Lightly rub with emery cloth any minor imperfections found in the deck taper. INSERT ½" BAR TO UNSCREW HEAD FROM SEAT PULLER STEM PUMP FLUID END DISCHARGE VALVE DECK INSTALLING ABRASION RESISTANT VALVES Install nitrile O-ring over the threaded section of the seat and position it at the bottom of the threads. Install the polyurethane insert into the valve and position it into the groove. Position the valve into the hole in the center of the installed seat. Install the valve spring. Apply anti-seizing lubricant to the threads of the valve cage and screw the cage on to the threaded valve seat

squarely setting the seat into the deck. Then pound the top of the stem with a 6 pound hammer. Unscrew the head and stem from the seat using a 1/2" bar (or screwdriver) into the hole provided at the top end of the stem. MA-300L MA-300M Use an anti-seizing lubricant in these threads. This is very necessary when seats and stems of Type 316 stainless steel are selected (optional) to prevent galling. Cleanliness of threads and other contacting surfaces is of paramount importance in the assembly of all valve elements.

19

VALVE SPRING OPTIONS All Myers Aplex Series valve springs are made of Inconel® material, precisely designed and fabricated. Unless otherwise specified, the standard spring is furnished. It provides excellent results in the great majority of applications. Pumps employed in marginally available NPSH conditions may require a softer spring, to reduce the required NPSH. For these special conditions, Myers Aplex Series can supply light valve springs which exert lower pressure on the valve disc. The use of light valve springs may be limited by the choice of plunger size and/or limited by the chosen speed of the pump. Light valve springs may be impractical for pump models fitted with their maximum plunger size, or which operate near top speed rating as disc bouncing and erratic seating may occur. VALVE DISC OPTIONS Myers Aplex Series acetal resin discs made of DuPont Delrin® are machined flat and smooth to produce perfect sealing on the lapped-flat face of the seat. Used successfully in thousands of applications, these discs are light, slightly flexible under load, and seal well, even at high pump speeds, providing smooth pump action. Acetal resins are very resistant to most corrodents but are not usually suitable in fluid temperatures above 120°F; nor do they afford long life at extreme pressures. Pressure limitations depend on valve size. But continuous valve operation at pressures above 2,500 psi usually indicate the need of metal valve discs. For higher temperatures or pressures, Myers Aplex Series offers lapped flat, hardened Type 17-4PH stainless discs, or titanium alloy discs. These metal discs are less tolerant of any fine grit in the liquid and are noisier than the acetal resin disc. PULLING THE VALVE SEAT First drain the fluid end entirely. For abrasion resistant valves, use the cage wrench to unscrew the cage from the seat. For disc valves unscrew the stem from the seat. Remove the cage, spring and valve from the fluid end. Attach the Myers Aplex Series puller head to the puller stem and tighten their tapered threads with a pipe wrench applied to the knurled areas of the puller stem and head. Lower the stem and head into the fluid end and engage the threads of the head onto the seat threads. Using a 1/2" bar (or screwdriver) rotate the head clockwise, threading it fully onto the seat. But do NOT tighten. Slide the bridge over the stem. Clean and oil the stem threads. Oil the face of the wing nut. Thread wing nut down onto the stem, seating it on the bridge top firmly. Extract the seat from the pump by striking the wing nut with a heavy hammer. A hydraulic ram may also be used. Stand clear of the pump when applying heavy tonnage, as the entire assembly will jump violently upward when the pulling energy is suddenly released. The Myers Aplex Series puller/setting tool and gauge tool are custom designed and built for each specific Myers Aplex Series pump model. The same puller head is used on both suction and discharge seats. The bridge is made to fit each model and its proper use will not damage the valve cover gasket machined counterbore on the top of the fluid end. SALVAGE OF WORN SEATS Rough valve seat faces may often be renewed by lapping or grinding, if not deeply fluid-cut. Perfect flatness is required. A surface grind, followed by lapping on a lapping plate provides excellent smoothness and the flatness needed for good sealing and smooth running. Metal valve discs may sometimes be salvaged by grinding or lapping, if not deeply cut or cracked. Delrin® discs are relatively inexpensive and salvage is seldom worthwhile. Replace the stem, if severely worn. Inconel® valve springs rarely require replacement. OTHER PUMP BRANDS Myers Aplex Series Industries can provide its unique (patented) valve to fit nearly all brands and models of multiplex pumps. An Myers Aplex Series seat setting/ puller tool is available, too.
