DRUM PLUTO 3 (01) PDF Document

1. Store in a dry and heated building.

2. Handle carefully and keep ports plugged to prevent ingress of dirt.

3. Rotate pump shaft occasionally to prevent seals sticking.

The DRUM PLUTO 3 pump is built with fine clearances. It is essential that a fine mesh filter is fitted on the suction side of the pump. If a reverse flow valve is fitted, a filter is also required on the other side of the pump.

The pump should be mounted with its shaft as near to a horizontal plane as possible. However, it can be inverted or side mounted if required. If mounted this way, it must be supported by both sets of feet.

The angle and length of the propshaft must be kept to an absolute minimum. Where these cannot be avoided, the propshaft should be balanced. The maximum angle of the propshaft under any conditions is approximately 12 degrees.

The centre line of the power take-off shaft must be parallel with the centre line of the pump.

When bolting the pipework to the pump (or reverse flow valve), care should be taken to prevent distortion of the body by misalignment. Additionally, adequate support should be given to the reverse flow valve, if fitted.

Should water enter the pump, oil should be flushed through immediately to prevent rusting.

The length of the suction pipe should be kept to an absolute minimum and the bore should be as large as the pump branches. The delivery pipework and hose should ideally be the same bore as the pump branches. As this is a very high capacity pump, to ensure full output, it is recommended that the pump is mounted on the trailer portion of articulated road tankers to give good suction conditions.

Ensure that the relief valve and spring are fitted in the suction side of the pump. See Service Instructions for details of how to interchange the relief valve and blanking plate.

The relief valve setting is 85psi (6Kp/cm²). Alternative spring settings are available on request. Please note the 2-stage relief valve fitted as standard will drop pressure by approximately 25psi (1.75Kp/cm²) when on full bypass, thereby reducing hose pressure and horsepower absorbed.

The DRUM PLUTO 3 pump is of internal bearing design and therefore must not be used to handle corrosive or abrasive products. You should check to confirm compatibility for the products you intend to handle.

The DRUM PLUTO 3 pump is suitable for handling viscosities up to 10,000 seconds RI (2,500 c.St.). For higher viscosities, you should seek advice on suitability and correct pump speed.

Thoroughly flush out the pump under pressure after discharging liquids with thermo setting properties. Otherwise, serious damage can occur when the pump is next started.

When handling viscous products and a reverse flow valve is employed, start with the valve in the neutral position, then gradually move the handle to increase flow. This will reduce the stock load on the drive system.

If the reverse flow valve is used infrequently, rotate it once a day to prevent sticking.

For the optimum discharge rate, start with a slow drive speed and gradually increase it until the pump starts to become noisy, then reduce the speed slightly until the noise disappears.

To clear the pump lines, increase speed or pump just prior to the compartment becoming empty. Revving the pump after it starts to pull air will not clear the lines. Do not run the pump at this elevated speed for more than approximately 60 seconds.

Do not run the DRUM PLUTO 3 pump dry. Also, this pump must not be run on full bypass for more than 3 minutes.

As the product lubricates the bearings and synchronising gears, no routine maintenance is required for the DRUM PLUTO 3 pump.

Should the pump become noisy during normal operation, it is essential that it is immediately removed from service and the reasons for the noise are investigated.
