Edwards E2M1.5 Vacuum Pump

Edwards E2M1.5 Vacuum Pump

New and unused in original Edwards Packaging

Complete with CD Instruction Manual, Ultragrade 15 Oil, fitting kit and packing slip

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.


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.


Applications

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



The pump is designed for reliable, long-term operation.

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.
