Refurbished Edwards E2M80 Dual Stage Rotary Vane Pump
The Edwards E2M80 is a dual stage rotary vane pump commonly used in a wide range of vacuum related industries. It incorporates forced oil lubrication to prevent oil starvation during high gas loads as well as an integrated gas ballast to assist with troublesome applications, such as those with condensable vapor content. For applications requiring inert fluids (e.g. Oxygen compatibility), the E2M80FX is used, containing PFPE oil instead of a standard hydrocarbon based fluid. The E2M80 is commonly configured for the integration of a mechanical blower, such as the Edwards EH500, which will greatly increase pumping speed.
E2M80s are offered with a full range of accessories to enhance operation including:
- MF Outlet Mist Filters – capture exhaust oil mists keeping them out of the exhaust system.
- ITF Inlet Dust Filters – installed at the pump inlet to prevent dust particles from accumulating in the pump oil and damaging the pump and its performance.
- ITO Catchpots – installed at the pump inlet to prevent liquids from accumulating in the pump oil and damaging the pump and its performance.
- ITC Inlet Chemical Traps – installed at the pump inlet to prevent aggressive vapors from accumulating in the pump oil and damaging the pump and its performance.
