WR®525 High Temperature Material

Thermoplastic Composite

WR®525 is a thermoplastic composite consisting of carbon fiber in a PEEK matrix. Because of its unique thermal expansion properties, WR525 is ideal for use as impeller wear rings, bushings and case wear rings.

WR525 allows the pump user to increase pump efficiency by running tighter wear ring clearances, while decreasing potential pump damage when pumps are cavitated or experience down-line bearing failures. WR525 is API 610 approved for (stationary/stationary and rotating) wear applications.
