E2M0.7 and E2M1.5 two stage oil sealed rotary vane pumps are renowned for achieving high ultimate vacuum and rapid 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 drive is provided through and Oldham coupling by a single phase motor.  The motor is totally enclosed and cooled by the motor-cooling fan which directs the air along the motor fins.  A thermal overload devise is fitted to the motor which switches off the pump if the motor gets too hot, this will automatically reset when the motor cools down and restarts the pump.


Technology

This is a two stage oil sealed rotary vane pump which 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, 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 an oil drain-plug to allow either gravity oil drain or pressure oil drain.
