PUMPGUARD Materials for Pump Wear Parts

Designed for pump bushing wear rings, guide bushings and thrust washers in liquid pumps

CPI PUMPGUARD™ materials for pump wear parts are proprietary polymer alloys for use in in-line shaft bearings, impeller wear rings, thrust washers on vertical pumps, barrel pumps, API bearings on Archimedes screws and horizontal pumps.

The CPI materials are intended to reduce diametral clearance on pump wear parts without the risk of damage to metal components. The properties of these materials are designed to help avoid catastrophic pump failures caused by dry-run start up or excessive vibration.

PUMPGUARD materials have a low coefficient of thermal expansion and provide excellent resistance to chemical attack as well as protection against impacts, thermal shocks, and hydrolysis. Applications using these materials significantly increase hydraulics, improving pump performance with reduction in energy consumption and reduced wear, which is reflected in maintenance and operating costs.
