Oil Lubrication/Sealing on Mechanical Vacuum Pumps

Fluids are required in mechanical rotary high vacuum pumps to lubricate bearing journals, rotors, as well as seal the interface between rotor/stator, vanes/end plates, etc. which otherwise provides a leak-path. Typical lubricating/sealing procedure is augmented by new method of fluid introduction into mechanism as a function of pump operation, eliminating eccentrics, valves, manifolds.
