Vacuum Pump Part Repair
All pumps face three problems; wear, corrosion and cavitation. Vacuum pumps are especially affected by wear and corrosion. Liquid ring pumps rely heavily upon the seal created by the cone and the rotor. If either of these are damaged or corroded the pump will begin to lose pressure and become inefficient. Other vacuum pumps, such as rotary vane pumps and screw vacuum pumps, also depend upon their components to create seals and maintain pressure. If pump component surfaces are worn down or corroded, they will no longer meet OEM specifications and the pump will become inefficient.
When pump components begin to wear or corrode, this does not mean they have to be doomed to the scrap pile. Instead of purchasing new components, most can be repaired via specialized machining and thermal spray processes. Wear and corrosion resistant coatings can be applied to repair pump components as well as extend the future life of the pump. These coatings can be built up and machined to meet the required operating dimensions.
Thermal spray remanufacture can
- Restore pump cone and rotor to OEM specifications
- Rebuild worn or corroded cone and rotor surfaces
- Repair damaged, worn rotor shafts
- Repair and prevent cavitation damage
- Prevent corrosion and damage on cast iron pump housings
- Increase efficiency by restoring pressure to worn parts
