Buy Edwards vacuum pumps from MSE Supplies at the best value. 

Known for their high ultimate vacuum ranges and rapid pumping speeds, these pumps are now the industry standard in a range of scientific and laboratory applications, and are ideal for backing your small turbomolecular pumps.

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. 

MSE Supplies is an authorized distributor of Edwards vacuum pumps.

Features and Benefits

Flexible and reliable

  • Compact in build and packing a punch, these pumps are available as free-standing units that are easy to deploy. With a series of wide voltage motors, you can achieve global coverage with less variants.

Easy to install

  • Installation is relatively simple with no customer wiring required - they come equipped with an integral IEC connector. The alternate side inlet connection port also allows you to install in height-restricted areas.

Built-in protection systems

  • The motor is enclosed and cooled by the motor-cooling fan and overheating protection is provided via a thermal overload device. Your EM pump is intelligent too. It automatically resets and restarts the pump when the motor cools down. No manual intervention is required.

Easy to maintain

  • The O-ring sealed sight glass makes inspection of oil level and condition simple too.
