Product Description
WR® 300 is a carbon-fiber reinforced compression molded PEEK™ often selected by pump manufacturers and users for pump bushings and case or impeller wear rings. Maximum service life is achieved in clean. lubricated and/or moist environments.

WR 300 allows the pump user to increase pump effiency by running tighter wear ring clearances while decreasing potential pump damage when pumps are cavitated or experience radial bearing failures.
