Rebuild Process

Rotary Vane Pumps and Boosters

Standard or basic rebuild price is quoted based on make and model number. The pump or booster is brought into the shop, completely disassembled, thoroughly cleaned and carefully inspected.

If the pump or booster requires only a standard rebuild or replacement of the O-ring, seals and the parts supplied in the rebuild kit, the repair process goes forward. If additional items, such as shafts, bushings, motor bearings are required, they are added as line items to the quote which is then supplied to the customer for approval.

If the cost is economical and it makes good business sense to go forward and rebuild the pump or booster, with the customers approval the work is completed.

After remanufacture, bench testing takes place at which time the rebuilt pumps are carefully evaluated for performance and checked for leaks.

The final step in the rebuild process is careful painting in the O.E.M. color scheme. Pumps that are shipped via UPS or common carrier are carefully packaged or crated to prevent damage in transit.

Piston Pumps

Standard rebuild is quoted and the evaluation process is the same as Rotary Vane Pumps. In addition, if water cooled, the block of the piston pump is flushed and if equipped with freeze plugs, they are replaced. Flow control valves are checked for mechanical function and actuator coils are replaced as part of the rebuild.

Diffusion Pumps

Teardown, cleaning and inspection is done in the shop. Heaters, wires, insulation and thermal switches are replaced and cooling lines checked for integrity. The body is painted in the O.E.M. color scheme and the lower portion has high temperature heat paint applied.
