Specs At A Glance

Good To Know

Q: What does the key do in this Water Pump Impeller & Key set? A: The key locks the impeller to the driveshaft so the impeller turns with the pump. Use it during assembly to secure the new impeller and prevent slipping.

Q: How often should the Water Pump Impeller & Key be replaced? A: Inspect the impeller at least once a year and replace it if the blades are cracked or worn. Frequent use in sandy or silty water can shorten its service life.

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