Pump Repair & Rebuilding
Pump work at Top Notch starts with a full teardown and measurement: shafts, bearings, seals, impellers and housings inspected, machined or replaced as the wear demands, then the unit is aligned, assembled and tested before it goes back into service — whether it came off a plant floor or a muddy jobsite.

Frequently asked questions
What pumps do you repair?
Vacuum pumps (liquid ring and rotary vane), slurry and dewatering pumps, hose pumps, twin-screw pumps and hydraulic pumps — rebuilt and tested in-house.
Do you test pumps after repair?
Yes. Testing before release is a fixed step of our repair process, not an option.
Can you rebuild a pump with discontinued parts?
In many cases, yes — our machine shop manufactures shafts and restores components that are no longer sold.
Do you offer emergency pump repair?
Yes — 24 hours a day, every day of the year, for the failures that stop production.
