If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Broken impeller vanes in Hurlcon pump, Foreign objects in volute, Loose impeller on shaft, Worn diffuser

Safety: Isolate power and close valves before disassembling the pump.

Inspect basket and volute: Remove pump lid and basket, then shine a torch into the impeller area. Remove any visible debris.
Check impeller play: Gently move the impeller by hand (with motor removed if necessary). Excessive wobble indicates damage.
Disassemble wet end: Remove the bolts joining the Hurlcon pump housing to the motor and inspect the impeller and diffuser for cracks or missing pieces.

Replace the impeller and diffuser with genuine Hurlcon parts if damaged.
