Leybold Pump Repair in Fontana
A tired Leybold 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 Leybold pumps working in vacuum systems — rotary vane, roots and dry pumps for coating, research and industrial processes 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 Leybold pumps lose their edge
The pattern we find at teardown on Leybold units is rotary vane wear and oil-seal leakage, roots rotor timing wear, and contamination damage from process backstreaming. 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 you rebuild Leybold pumps for coating and research duty?
Yes — vane, roots and dry units are stripped and measured, timing and clearances reset, seals renewed, and ultimate vacuum 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.
Do you offer emergency pump repair?
Yes, 24 hours a day, 365 days a year. Call (800) 821-3404 or (949) 400-2937.
