UK-Made Mechanical Seals for Your Equipment

Reliable seals, designed, built and repaired in the UK to keep your pumps, mixers and rotating equipment running smoothly.

Pump Repair

Professional pump repair that restores performance and cuts costs

A pump rarely fails instantly. Flow drops, noise increases, vibration builds and the mechanical seal starts running hotter. Most pumps can be restored through a proper pump repair, rather than being replaced at unnecessary cost.

We rebuild pumps to the condition they should have been in from the start. 

What our pump repair service includes

A pump repair is a full engineering rebuild, not a quick tidy-up. We strip the pump down completely, clean it and carry out a full assessment of every component: 

Shafts replaced or rebuilt

Bearings replaced

Sleeves, wear rings and bushes restored

Clearances corrected

Corrosion removed

Seal chamber repaired

Mechanical seal refurbished or replaced

Once rebuilt, the pump usually runs smoother, quieter and more efficiently than it has in years.

Why choose Pump Repair?

A proper pump repair typically costs around half the price of a new pump, with none of the disruption associated with replacing equipment. 

No pipework changes

No new bases

No reengineering

Most importantly, pump repair tackles the real cause of the failure so the pump stays reliable long-term.

We repair all industrial pump types

We carry out pump repair on:

Centrifugal pumps

Lobe pumps

Progressive cavity pumps

Submersible pumps

Slurry and wastewater pumps

Hygienic pumps

Chemical and solvent-duty pumps

Legacy or obsolete OEM units

Missing nameplate? Worn beyond recognition? No issue. We work from dimensions and internals.

Mechanical seal replacement or refurbishment

Every pump repair includes an inspection of the seal chamber. We either fit a new seal or refurbish the existing one depending on what delivers the best long-term performance and value.

ATEX pump repair

If your pump runs in a hazardous zone, we supply seals rated to ATEX Category 2, Zone 1 and Zone 21, ensuring the repaired pump remains compliant.
