Vacuum Pump Repair

All work areas and systems meet stringent EPA and OSHA requirements.

PHASE 1

Pumps are broken down at designated workstation under exhaust hood. Protective gloves, eye goggles, breathing apparatus and aprons are required. All parts are initially cleaned with biodegradable chemical degreaser (soapy solution), then rinsed with water and blow dried with compressed air.

PHASE 2

Surfaces of all components are stripped down to bare metal by means of glass bead blast machine then blown off with compressed air. Components are then rinsed with solvent leaving surfaces virtually free of all harmful residues.

PHASE 3

All critical dimensions of moving parts and mating surfaces are measured and inspected to 1/10,000 millimeters of compliance to factory specifications and tolerances. Mating surfaces and O-ring surfaces are hand lapped to precise finishes. All other components are discarded and replaced.

PHASE 4

Pump is assembled at designated clean area. Gaskets, seals, and O-rings are replaced, along with any other component or components that do not meet factory specifications and/or tolerances

PHASE 5

After pump has been properly assembled; it is forwarded to designated bench test station.  A vacuum gauge is used to test absolute vacuum pressure and a thermocouple gauge, in conjunction with a given volume (test tank) can be implemented to qualify acceptalbe pumping speed.
 
PHASE 6
 
After assembly, pump is testedd, monitored and recorded on a test sheet.  Checking pressure and temperature.
 
PHASE 7
 
Once approved, protecteve cap plugs are inserted into intake and exhaust ports of pump to prevent foreign matter.  Pump is then forwarded to approved exhaust paint booth and pump is prepared and spray-painted.
 
PHASE 8
Necessry paperwork is attached to ump including a sticker and tag showing pump testing results and particulars.
