Industrial and commercial pump servicing & maintenance

Repair, Don’t Replace
With a fully equipped workshop at our disposal, we can often provide a temporary replacement pump to minimise disruption to your operations.
A complete refurbishment or system overhaul can also lead to reduced energy consumption and help lower your environmental impact.


We can work on a range of pumps
- Axial flow
- Booster sets
- Centrifugal
- Dosing
- In-line circulating
- Multi-stage
- Self-priming
- Slurry
- Submersible
