Edwards, E2M0.7

Edwards EM Series (Small)

E2M0.7 / 1.5

The E2M0.7 and E2M1.5 pumps are two-stage, direct drive, sliding vane pumps. The pump is oil-sealed and designed for reliable, long-term operation. The pump is a free-standing unit. The drive is provided through an Oldham coupling by a totally enclosed fan cooled single phase motor. The pump is well suited for scientific applications such as backing turbomolecular pumps and general laboratory applications.

Applications

  • Analytical instruments
  • Leak detectors, helium
  • Research and development
  • Backing turbomolecular pumps

Features and Benefits

  • E2M0.7 has very low sound level of 43dB(A)
  • The pump is designed for reliable, long-term operation
  • Compact dimensions
  • Low energy consumption
  • Low operating temperature will minimise the heat load on the equipment
  • The pump is a free-standing unit
  • The motors are totally enclosed and are cooled by the motor-cooling fan and protected by a thermal overload device
  • Full height O-ring sealed oil sight glass for easy checking of oil level and condition
  • Gas ballast valve for water vapour handling capacity
  • Approved to EN61010, CSA, C22.2 and UL61010

EM18 & EM 28

The EM range of oil-sealed rotary pumps - renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour - have become the industry standard for laboratory and light industrial applications. The pump is a freestanding unit with the drive provided through a flexible coupling by either a single-phase or three-phase (four pole) motor.

Applications

  • Analytical instruments
  • Leak detectors, helium
  • Research and development
  • Backing turbomolecular pumps
  • Automotive
  • Beam lines and high energy physics
  • Centrifuges, ultra-high speed
  • Coating

Features and Benefits

  • The pump is designed for reliable, long-term operation
  • Thermal overload device prevents overheating (single phase only)
  • The drive is provided through a flexible coupling by a single-phase or three-phase (four pole) motor
  • The motors are totally enclosed and are cooled by the motor cooling fan
  • Full height O ring sealed oil sight glass for easy checking of oil level and condition
  • Large sight glass and operating oil range
