Vacuum Research Corporation's oil-free mechanical vacuum pumps are multi-stage, reciprocating piston devices. These pumps have four stages of compression, producing overall compression ratio of approximately 50,000 to 100,000 using piston, cylinder and stage interconnection designs. The Absolute 500 is a 500 l/min (16cfm) mechanical vacuum pump which provides evacuation capabilities from 1 atmosphere to an ultimate pressure of less than 20 microns (2 x 10-2 Torr), featuring an NW40 inlet flange.
      
These pumps are especially useful for initial evacuation of chambers which are then pumped by cryopumps, turbo molecular pumps, or ion pumps. They can also be used as clean backing pumps for turbo pumps and have a proven expected life in excess of 10,000 hours of continuous operation.
      
The pump does not require any lubrication and therefore produces a hydrocarbon-free vacuum, eliminating the possibility of vacuum chamber contamination. The two inlet cylinders are connected in parallel to obtain a combined average pumping speed. The third cylinder has two stages of compression (one in front of piston, and on back side).
      
The pistons utilize a stepped design. Both larger and smaller cylindrical surfaces have liners made of low friction coefficient, reinforced polytetrafluoroethylene (PTFE) material. The liners serve as bearing material and provide the necessary high impedance for leakage from high to low pressure side. At the ends of the smaller diameter section, flexible seals minimize the in leakage of atmospheric air. The back side so fall pistons, except the last, are connected to the next stage.
