Specs At A Glance

Good To Know

Q: How do I know my wear ring needs replacing? A: Cavitation, slipping out of the hole, or a visible gap around the impeller usually point to a worn ring. Measuring the inside diameter against 155.5 mm gives a clear answer.

Q: Does the impeller need to come out to install it? A: Yes, the pump typically comes apart to press the old ring out and seat the new one squarely. Confirm the impeller and housing are still serviceable while the pump is open.

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