In house facilities

Pump testing

Pump test curveAfter pump repair or servicing, we use an array of specialised facilities to fully test each pump. A full performance test curve is also provided prior to dispatch to confirm optimum performance and provide engineers with a datum to work from when installing the pump. Dedicated test areas include:

Small/medium test rig: full load testing up to 500kW, flow up to 10,000 igpm, + 2,700 M3/Hr and heads up to 10,000 ft, 150 Bar and 2170 PSI. Net Positive Suction Head tests can be carried out in house and our hydrostatic pressure test rig can test up to 250 bar.

Large test rig: Bespoke testing facility for high flows that can be customised to suit your requirements. We also partner with a local dry dock to test larger pumps, submersible and vertical, up to 11kV.

Fitting facilities

We have a wide range of fitting facilities, including bench tools for all pumps, torque equipment, a full range of calibrated measuring equipment and a range of presses to enable the removal of impellers, couplings and bearings.

We have lifting capabilities up to 40 tonne, 5m x 6m access and a 13m (42ft) working height to handle most pumps.

Mechanical repair

We have full machining and shaft repair facilities to cover all the mechanical aspects of the pump repair and reverse engineering capabilities for obsolete and long lead parts.

Shafts can be radiographed, NDT tested, and PMI tested to ensure optimum quality and maximise the life of the pump.


With balancing multiple facilities up to ten tonnes for impeller and rotor balancing, all impellers are balanced prior to assembly. We strive to balance to as close to G1 as possible, without compromising the impeller, to ensure smoother operation and prolong bearing life.

Seals and spares

We work in partnership with all major manufactures to ensure quick turnaround of all mechanical seals and spare parts.

Other services

We also offer protective performance coatings, as required, to improve pump efficiency. Where parts are obsolete or original spares are unavailable or no longer fit for purpose we can reverse engineer all parts from improved performance. We can also design and specify systems from scratch and have full AutoCAD capabilities in-house to support these projects.

On site services

We also offer on site support services including installation and removal of pump, laser alignment, condition monitoring (including vibration and thermographic analysis), balancing and repairs on site.

Our customer service and in-house pump repair service

We minimise customer downtime by operating a 24-hour, 7-day-a-week emergency pump repair service that is operational 365 days a year and can work around the clock to minimise customer downtime and get your pump back up and running quickly.

Specialising in the upgrade and refurbishment of pumps, we utilise our in house testing and diagnostic experience and reverse engineering and design capabilities to improve efficiency and reliability of customer critical assets.

By carrying out the complete pump repair in-house we are able guarantee the quality, delivery and cost to meet your requirements. In addition to pumps we can also service all associated motors giving customers one point of contact for the full system and a performance guarantee.

We are an IECEx approved overhauler of Ex-rated pumps and motors. Take a look at our project testimonials, enquire about our pump repair service, or contact us today if you require any more information.
