Rotary Vane Pump Repair in Fontana
A tired Rotary Vane pump rarely quits without warning — it loses flow, loses pressure or vacuum, runs noisy and hot, and only then stops the process behind it. We repair and rebuild Rotary Vane pumps working in rotary vane vacuum pumps and compressors in packaging, printing, woodworking and laboratory service at our Fontana shop — strip, measure, renew the wear parts, reset internal clearances and test the finished pump so it goes back to work doing what it was built to do. Everything is done at 14166 Whittram Ave by the crew that quoted it, with no work farmed out.

Where Rotary Vane pumps lose their edge
The pattern we find at teardown on Rotary Vane units is vane wear and sticking from contaminated oil, scored stator bores, and exhaust-valve fatigue that costs vacuum and fills the room with mist. Rather than swapping parts on suspicion, we measure first — rotor, vane, piston and wear-plate clearances where they apply, shaft runout, bearing condition, seal faces and housing wear — then quote the renewal the measurements actually justify. Machining and manufacture happen in-house, so a worn shaft, a scored housing bore or a discontinued wear part is a shop job here, not a reason to scrap the pump. Rebuilt pumps are assembled with new seals and bearings, clearances set to specification, and test-run — flow, pressure or vacuum checked against the duty — before they leave Fontana.

Frequently asked questions
Can scored rotary vane pump bores be repaired?
Yes — bores are measured and honed or restored in-house, vanes and valves renewed, oil system cleaned, and vacuum performance verified on test before release.
Is my pump worth rebuilding or should I replace it?
If the housing, rotors and shaft are sound, a rebuild with renewed wear parts usually restores full performance for less than replacement — we measure first and tell you plainly which side of that line your pump is on.
