Rebuilt and tested, or it does not ship

Pumps are torn down and measured — shafts, bearings, seals, impellers and housings — then machined, resealed, aligned and tested before they go back into service. From process pumps to dewatering units, the work is done in-house in Fontana, with rush turnarounds when a line or a jobsite is standing still.

Signs your pump is on the way out

Whining or cavitation noise, weak or slow functions especially when hot, foaming or discolored oil, and metal in the filter all point at the pump or its inlet conditions. Inlet problems — a collapsed suction line or starving strainer — kill good pumps, so the diagnosis covers the circuit, not just the component. Regular hours Monday–Friday 6 AM–5 PM; rush line 24 hours daily; free pick-up, delivery and quotes.

  • Piston, vane and gear pump rebuilding
  • Pump testing and verification
  • Suction and cavitation diagnosis
  • System contamination cleanup
  • PTO and truck hydraulic pumps

Frequently asked questions

Do you test hydraulic pumps after rebuilding?

Yes — testing is a required step in our process before any rebuilt pump is released.

Why did my new pump fail quickly after installation?

Usually contamination or an inlet problem that was never corrected. We diagnose the circuit along with the pump so the cause is fixed with the component.
