Grinder pump support

Grinder pumps are used in foul water and wastewater applications where solids reduction, small bore discharge pipework or difficult pumping conditions need to be considered.

Grinder pump repair and replacement

We can help with blocked grinder pumps, failed motors, poor pumping performance, tripping electrics, float faults, control panel issues and replacement pump selection.

Correct pump selection matters

A grinder pump must be suitable for the application, duty, head, discharge pipework and incoming flow. We can advise on replacement and installation considerations before supplying equipment.

Fault finding and self-help

Common symptoms, safe checks and likely causes

Grinder pumps need careful diagnosis because faults can relate to cutter condition, solids loading, discharge pipework, controls or unsuitable items entering the system.
