Specs At A Glance

Good To Know

Q: How do I know the wear ring needs replacing? A: Cavitation, vibration, or a drop in top speed during acceleration typically points to excessive clearance between the impeller and the ring. Inspecting the ring for scoring or grooves confirms whether replacement is needed.

Q: Does this ring come with mounting hardware? A: This listing covers the wear ring itself unless otherwise stated. Reuse or replace fasteners as needed per your pump assembly.

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