Repair experience with Waukesha sanitary pumps
American Gearbox Repair repairs and rebuilds Waukesha Cherry-Burrell positive-displacement rotary lobe pumps — the sanitary pumps used throughout food, dairy, beverage, pharmaceutical and personal-care processing. Our repair experience covers Waukesha Universal I, Universal II and Universal III series pumps, along with the gearboxes, timing gears and seal arrangements that keep their rotors turning in perfect sync.
Please note: we are not an authorized dealer or authorized service center for Waukesha or Cherry-Burrell. We repair Waukesha equipment based on our repair experience, using careful inspection and rebuilding practices developed over years of working on sanitary pumps and gear-driven equipment.
Sanitary pumps have to hold tight internal clearances to move viscous product without damage, and to survive daily clean-in-place cycles. We measure every clearance and rebuild to restore pumping efficiency, not just to stop the leak.
Common Waukesha pump problems we fix
- Rotor wear and clearance loss — worn rotors and pump bodies causing lost flow, poor suction and product slip
- Seal leaks — failed single or double mechanical seals, worn seal faces and damaged O-rings
- Timing gear wear — worn or chipped timing gears letting rotors contact each other
- Bearing failure — worn gearbox bearings causing noise, heat and shaft misalignment
- Shaft wear — scored seal areas and worn bearing seats on pump and drive shafts
- Gearbox oil contamination — product or wash water getting past seals into the timing gearbox
How we rebuild your Waukesha pump
1. Teardown, cleaning and measurement
We strip the pump completely, clean all product-contact parts, and measure rotor-to-rotor, rotor-to-body and shaft clearances, along with gear backlash and bearing fits in the timing gearbox.
2. Repair and replacement
Worn rotors are reconditioned or replaced, shafts are reground or replaced, timing gears are renewed, and seal bores and bearing bores are repaired. All product-contact surfaces are finished to a sanitary standard.
3. Reassembly and testing
The pump is rebuilt with new bearings, seals and elastomers, timing is set precisely, and the unit is run-tested for flow, pressure, noise and leaks. Every rebuild is backed by our 24-month warranty.
Replacement components
Rotors, bearings, mechanical seals, O-rings, timing gears, shafts, seal sleeves, gaskets and gearbox components. We use food-grade-compatible materials where the application requires them.
