E2M1.5

The E2M1.5 is a two stage oil sealed rotary vane pump suitable for many bench type applications. The pump features an alternative inlet connection position at the side of the pump so that overall installation height can be reduced to a minimum when required.

The interstage version features an additional pumping port to provide a rough vacuum for auxiliary duties.

Features and Benefits

  • The pump is designed for reliable, long-term operation.
  • Compact dimensions.
  • Low energy consumption.
  • The interstage version features an additional pumping port to provide a rough vacuum for auxiliary duties.
  • The pump is a free-standing unit.
  • 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.
  • Easy to use controls
  • Pressure die cast oil box with integral oil seals prevents oil leaks.
  • Gas ballast valve for large water vapor handling capacity.
  • Externally approved to EN61010, CSA, C22.2 and UL61010.

Applications

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