EM Series pumps are rugged, mechanical oil-sealed pumps in a compact and quiet design. They feature advanced lubrication circuits, high reliability, and accessories to suit your specific application needs. Ideal for dealing with extreme gaseous environments such as pharmaceutical freeze drying or refrigeration system evacuation, the EM series is the industry standard for zero contamination of process and effective lubrication under high gas loads.

Edwards E2M series two stage oil sealed rotary vane vacuum pumps are renowned for their high ultimate vacuum, rapid pumping speeds, quiet operation and ability to handle water vapour. These direct drive rotary vane pumps are inherently compact and vibration free, and with their finger-proof fan and coupling housings they offer excellent operator protection. A comprehensive range of accessories is available to allow use on a wide variety of vacuum applications. Pumping speeds of either 0.7 to 178 m3h-1
