The EDWARDS E2M 40-275 two-stage rotary vane vacuum pumps are designed for demanding industrial applications requiring low ultimate pressure, high pumping speeds, and reliable continuous operation.
The range includes the E2M40, E2M80, E2M175, and E2M275, with pumping speeds from 37 to 255 m³/h at 50 Hz and an ultimate total pressure of 3 × 10⁻³ mbar without gas ballast. Their proven two-stage oil-sealed design and forced lubrication system provide stable vacuum performance across a wide range of industrial operating conditions.
The E2M pumps feature an adjustable gas ballast with a built-in dust filter and purge gas connection. An oil distribution system maintains a constant oil supply to the vacuum stage during operation, while the integrated oil filter helps protect the pump mechanism from solid contamination.
For applications requiring higher pumping speeds or improved ultimate pressure, the EDWARDS E2M range can be combined with an EH Roots vacuum booster to create a higher-performance vacuum pumping system.

The E2M 40-275 pumps are suitable for vacuum coating processes requiring high pumping speeds and low, stable ultimate pressure.
The range is suitable for pharmaceutical freeze-drying processes. EDWARDS specifically recommends the AZ variant for applications requiring azide compatibility.
E2M pumps can be integrated into plasma treatment processes. For oxygen-rich plasma applications, EDWARDS recommends the FX variant, which is PFPE-prepared for pumping gas mixtures with oxygen concentrations above 21%.
E2M pumps are suitable for heat pipe applications requiring reliable and controlled vacuum conditions.
The range is also suitable for heat treatment processes, combining low ultimate pressure with a robust design for demanding industrial applications.
Specific E2M versions are available for applications in the chemical process industry. The E2M Ex Series is ATEX certified for use in and with potentially explosive atmospheres.
