Frequently Asked Questions

Still have questions? Here’s what customers ask us most.

We repair a wide range of pumps, including submersible, centrifugal, dosing and metering, vacuum, sewage and wastewater, and chemical pumps. We also repair complete motor pump units. Tell us what you have, and our engineers will assess it and recommend the right repair.

We repair pumps from a wide range of manufacturers, including Flygt / Xylem, Grundfos, Ebara, Lowara, KSB and Sulzer. If yours isn’t listed, contact us and our engineers will take a look.

A leaking pump needs its mechanical seal and O-rings or gaskets replaced. Noise usually means worn bearings. A loss of flow or power can point to damage or wear on the impeller. Send it in, and we’ll find the cause.

We assess every pump before any work starts. If it can’t be repaired, we’ll tell you and quote for a new pump to match your original specification instead.
