Slurry Pump Material Codes

May 28, 2019

Spare parts for Slurry Pumps mainly comprise Impellers, casing liners, Shaft Sleeves, Seals, Shaft seal parts, and Bearings. It is recommended that an appropriate number of each of these replacement parts be kept in stock as required to avoid disruption of slurry pump operation, depending on the estimated life of wear components.

 

Where a large number of Slurry Pumps are installed, it is recommended that a spare Bearing Assembly be held for every ten (or less) slurry pumps of the same size. This enables maintenance related slurry pump down-time to be minimised. Ideally Bearing Assembly replacement can be carried out during scheduled shut-downs for slurry pump wear part replacement. The worn Bearing Assembly may then be removed to a workshop, inspected, overhauled if required, and held ready for the next replacement.

 

This procedure minimises both damage resulting from component failure in operation, as well as process and slurry pump down-time associated with these unscheduled failures.
