Brochure E2M Rotary Vane Pumps
E2M 40-275 Rotary Vane Pumps
Designed for reliable, long term operation
Rugged, mechanical oil-sealed rotary vane vacuum pumps with a proven robust design
E2M series pumps are rugged, mechanical oil-sealed rotary vane vacuum pumps with a well proven robust design. They feature advanced lubrication circuits and come with tough accessories to suit almost every application need.
Reliable design and technology
Proven design for over 30 years in the market. Built-in oil filtration with disposable oil filter and forced oil lubrication to ensure efficient and effortless operation of the pump mechanism at any inlet pressure.
ATEX versions for explosion-proof compliance
E2M Ex Series to pump or operate in environments where a potentially explosive atmosphere can be present. Edwards can offer a wide range of products for use in and with explosive atmospheres. They are certified for ATEX and other applicable global standards.
Get the right series for your need
HC Series with hydrocarbon oil for most of the applications, FX Series for pumping rich-oxygen gas mixtures (PFPE prepared) and AZ Series for applications with chemically active compounds (Azide compatible).
E2M with EH booster combination
- Combine the E2M with an EH booster to obtain additional pumping speed and improved ultimate pressure.
- Our unique pumping system EM275/EH4200 offers enormous suction speed to pump out large chambers quickly at very low pressure.
