Overview

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) air cooled motor.

Each EM pump is supplied with 2 x 1 litre of Ultragrade 19 oil, O ring and centering ring, two Allen keys and spares seal for oil drain and filter plugs. For PFPE prepared FX pumps Fomblin® to be ordered separately.


Technology

The motor is totally enclosed and is cooled by the motor-cooling fan which directs air along the motor fins. The motors are fitted with a thermal overload device. When the motor is too hot, the thermal overload device switches off the pump. The thermal overload device has an automatic reset; when the motor cools down, the device resets and the motor will restart. 
  
An oil pressure system 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, so this arrangement 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 two oil drain-plugs to allow either gravity oil drain or pressure oil drain.


Features

  • 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.
  • IE3 energy efficient 3 phase motor used with E2M28.
