EM Oil Sealed Rotary Vane Pumps

Designed for reliable long term operation

EM28 Rotary Pump

E2M0.7-28 rotary vane pumps - Delivering high ultimate vacuum and rapid pumping speeds

Small EM oil sealed rotary vane pumps are renowned for achieving high ultimate vacuum and rapid pumping speeds with quiet operation and the ability to handle vapour. These pumps have become the industry standard in a range of scientific, laboratory, and light industrial applications, and are the ideal partner for backing your turbomolecular pump.

Edwards Production

Industry proven long term reliable performance and compact in design, these oil sealed pumps are free-standing units. Simple installation and operation with no customer wiring required and for the E2M0.7 and 1.5 an alternate side inlet connection port so that overall height can be reduced to a minimum when required. Most single phase versions are equipped with an integral IEC connector and on/off switch for local control and easy connections to the mains electric supply.

Features & Benefits in a nutshell

  • Quiet operation: For a better working environment.
  • Flexibility of use: Freestanding unit compact design.
  • Reliable performance: Proven in a range of laboratory and industrial applications over many years.
  • Gas ballast valve: Used when pumping vapour.
  • Built-in protection systems: The motor is enclosed and cooled by the motor-cooling fan which directs the air along the motor fins. Overheating protection is provided via a thermal overload device which is fitted in the motor and switches off the pump if it gets too hot, this will automatically reset when the motor cools down and restarts the pump. No manual intervention is required.
  • Easy to maintain: The O-ring sealed sight glass makes visual inspection of the oil level and conditions simple. The oil drain port is located at the end of the oil box for draining oil out of the pump. A large oil filling port and recess in the top of the oil box top makes oil top-ups easy.
