Warman Slurry Pump Maintenance Manual

Warman Slurry Pump Maintenance Manual

Slurry pump maintenance manuals are important tools to help ensure a slurry pump continues to operate at its peak performance.warman slurry pump maintenance manual A proper maintenance plan will help to extend the life of your slurry pump and improve overall operating costs. Whether you need a new slurry pump or are in need of repairs, these maintenance manuals will provide the information and guidelines you need to make the right decisions for your application.

In addition to the general procedures, each type of slurry pump has specific requirements that should be followed.warman slurry pump maintenance manual These include the use of recommended lubricants, inspection intervals, and service intervals. A comprehensive slurry pump maintenance program will also maximize the lifetime of your mechanical seal.

Lubricants

The slurry pump manufacturer recommends the use of Lithium soap base grease with EP additives for normal operating conditions. The lubrication system should be flushed periodically with clean water.

Lubrication

The mechanical seal life is greatly influenced by the cleanliness of the pumped fluid and the surrounding environment. This is why it is difficult to give a definitive indication of the life of a mechanical seal under any particular condition.

Ensure that the gland is free of dirt, debris, and other obstructions that could cause contamination of the mechanical seal. If possible, have a qualified professional perform an inspection of the gland and surrounding area. It is also a good idea to check the temperature and vibration of the pump. These can be signs of a leaking mechanical seal or other problem.

Drainage

The drains and piping should be clear of blockages, debris, and other obstructions that could prevent the discharge of the pump. The drains should also be inspected for signs of corrosion. A blocked or restricted drain can lead to a loss of suction power, overheating, and damage to the mechanical seal.

Auxiliary piping

If the pump requires auxiliary piping for bearing cooling, seal chamber cover cooling, or mechanical seal flush, consult the data sheet for specific piping recommendations. In general, auxiliary piping should flow at a minimum rate of 1 gpm (4 lpm).

Axle alignment

Coupling or v-belt drive units must be properly aligned to the shaft in order to reduce the risk of catastrophic drive failure and unintended contact between rotating components. To verify shaft alignment, shut down the pump and driver and follow the coupling or v-belt drive manufacturer’s instructions for removal. Once the v-belt or coupling guard is removed, refer to the Pump-to-Driver Alignment for Coupled or V-Belt Drive Units section in this chapter for steps to correctly align the unit.
