Good To Know

Q: What does a jet pump wear ring do? A: It maintains the close clearance between the impeller and pump housing so the pump keeps moving water efficiently. A worn ring lets water slip past the impeller, cutting thrust and top speed.

Q: How do I know my wear ring needs replacing? A: Common signs include cavitation, sluggish acceleration, and visible scoring or gaps between the impeller and ring. Inspecting the pump during service is the most reliable check.

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