Specs At A Glance

Good To Know

Q: How do I know if my wear ring needs replacing? A: Check the gap between the impeller blades and the ring; a visible gap or grooved surface means the ring should be replaced. Loss of acceleration or cavitation on takeoff are common signs.

Q: Does this ring need to be pressed in? A: Most pump housings accept a wear ring with a press or drift fit after thorough cleaning of the bore. Verify the housing bore diameter matches the ring's outer dimension before installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
