Fontana Pump Repair & Rebuilding

When a pump will not hold prime, starts cavitating or keeps chewing through seals, it is warning you — and catching that warning early, before the housing is wrecked, nearly always costs less. At our Fontana workshop we rebuild vacuum, slurry, hydraulic and industrial process pumps, machine what we need on site and prove every pump on test before it returns to duty.

Rebuilds for the pumps local industry depends on

Vacuum pumps in liquid ring and rotary vane designs, slurry and dewatering units, hose pumps, twin-screw and gear pumps, and hydraulic pumps in every layout come through this bench — each one stripped, measured, machined and rebuilt with worn parts renewed and clearances brought back to specification.

However different the pumps are, each rebuild finishes identically — on test. Nothing leaves here until it has been run and checked.

From first call to final test in eight steps

Each engagement follows the same eight stages and ends with a checked component or machine back in service.

01

Pick-up arranged

Where applicable, we organise collection of the equipment or component at no charge.

02

Full inspection

The unit comes apart so the whole failure can be properly assessed.

03

Evidence on camera

We record the condition and findings in photos and video to support an open repair discussion.

04

Quoted scope

The work we recommend is set out and priced before any of it goes ahead.

05

Your approval

We confirm what will be done, how quickly it is needed and the practical way forward.

06

Making what's needed

Components are machined, welded, rebuilt or reverse-engineered in-house.

07

Verification testing

Before release, we confirm the unit operates as it should and the workmanship holds up.

08

Back to work

The completed component or machine is returned, ready to earn its keep again.

Common questions, straight answers

Is it better to rebuild my pump or buy a new one?

Provided the housing and core parts remain healthy, rebuilding normally brings back full performance for less money than a replacement — and on plenty of industrial models it is quicker than waiting for a new unit to arrive. We will inspect the pump and price the job before you have to choose.

Which pump families do you rebuild?

Vacuum pumps of the liquid ring and rotary vane kinds, slurry and dewatering pumps, hose pumps, twin-screw pumps and hydraulic pumps.

Do rebuilt pumps get tested before they go back?

They do — testing sits at step seven of our process, and a rebuilt pump is proven before it is handed back.

What about parts for older pumps?

Frequently we can source them — and where a part has been discontinued, the machine shop can make a replacement or restore the original, shafts and wear components included.

Down right now? The rush line answers day and night.
