Good To Know

Q: What does a wear ring do in a jet pump? A: It maintains the tight clearance between the impeller and pump housing so water is pushed efficiently instead of leaking past the blade tips. A worn ring causes cavitation and lost thrust.

Q: How do I know the wear ring needs replacing? A: Common signs include reduced top speed, sluggish acceleration, or visible scoring and grooves on the ring surface. Inspecting clearance during pump service is the best way to confirm.

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