Hydraulic Pump and Motor Repairs in the Civil Engineering Sector
We offer turnkey civil engineering hydraulic repairs, covering all brands of pumps and motors. Our team starts with a free strip-down and diagnosis before carefully replacing or refurbishing any worn parts. We renew all seals and refresh mating surfaces, followed by rigorous testing under simulated operational conditions with our in-house test rig.
Every hydraulic pump and motor repair we conduct is covered by a comprehensive 12-month warranty for your complete peace of mind.
Why Hydraulic Repairs Are Essential for the Civil Engineering Sector
The civil engineering sector relies on a huge variety of hydraulic equipment, from bulldozers and dumpers to excavators, breakers, trenchers and more. When these tools fail, work stops, causing delays, unforeseen costs and knock-on effects.
Our hydraulic pump and motor repairs help keep the civil engineering sector operating like clockwork, getting crucial machinery back up and running quickly and reliably.
We strip and inspect all hydraulic units FREE of charge
