About Grundfos sewage and wastewater pumps
Grundfos is a Danish pump manufacturer founded in Bjerringbro in 1945 by Poul Due Jensen. The brand is widely used across building services, water supply, drainage, wastewater and sewage pump applications, including submersible pumps, controls and pump station equipment.
Common Grundfos sewage pump problems
Typical issues include high level alarms, blocked impellers, pumps running but not emptying the chamber, tripping electrics, worn mechanical seals, failed float switches, non-return valve problems and incorrect duty selection after a previous replacement.
Grundfos pump repair, replacement and servicing
Alton Pumps can help identify whether a Grundfos pump fault is caused by the pump, control panel, floats, valves, pipework or site conditions. Where replacement is needed, we can help match the existing model, check duty requirements and advise on a suitable sewage pump replacement.
