Edwards E2M1.5 vacuum pump

The E2M1.5 two-stage oil sealed rotary vane pumps are specifically designed to achieve ultimate vacuum and pumping speeds, with quiet operation and compact size. Providing long term reliability, these pumps have become the industry standard in range of scientific and laboratory applications, and the ideal partner for your tubomolecular pump.The motor is completely enclosed and cooled by the motor-cooling fan, which directs the air along the motor fins. A thermal overload device is fitted to the motor which switches off the pump in the case that the motor gets too hot. This will automatically reset when the motor cools down and restarts the pump.The E2M1.5 vacuum pump also has a pressurised oil system that lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior (suckback) after the pump stops. The pumping chambers are air-tight, which prevents oil suckback unless t...

The E2M1.5 two-stage oil sealed rotary vane pumps are specifically designed to achieve ultimate vacuum and pumping speeds, with quiet operation and compact size. Providing long term reliability, these pumps have become the industry standard in range of scientific and laboratory applications, and the ideal partner for your tubomolecular pump.

The motor is completely enclosed and cooled by the motor-cooling fan, which directs the air along the motor fins. A thermal overload device is fitted to the motor which switches off the pump in the case that the motor gets too hot. This will automatically reset when the motor cools down and restarts the pump.

The E2M1.5 vacuum pump also has a pressurised oil system that lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior (suckback) after the pump stops. The pumping chambers are air-tight, which prevents oil suckback unless the gas ballast valve is open.

You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass. An oil filler-plug is fitted to the top of the oil box. The pump has an oil drain-plug to allow either gravity oil drain or pressure oil drain.

Applications:

  • Analytical instruments
  • Laboratory bench top vacuum
  • Leak detectors, Helium
  • Research and development
  • Backing turbomolecular pumps
