Good To Know

Q: How do I know the wear ring needs replacing? A: Common signs are cavitation, slipping acceleration, and visible scoring, gouges, or excessive clearance between the impeller and the ring.

Q: Does the ring come with an impeller or other pump parts? A: This listing covers the wear ring only, so reuse or replace the impeller and seals as your inspection requires.

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