Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
What it is
How it works
An oil seal between the vanes and the chamber wall prevents backflow of gas and lubricates the bearing surfaces and rotor sealing faces.[2]
Where it fits in the process flow
The Edwards E 2 M 2 is a free-standing pump that draws vacuum on a chamber or foreline.[2]

Frequently asked questions
What type of motor does the Edwards E 2 M 2 use?
The Edwards E 2 M 2 uses a single-phase or three-phase, four-pole, totally enclosed motor. Single-phase motors have an on/off switch and either an automatic or manual reset thermal overload device.[2]
What is the inlet port type on the Edwards E 2 M 2?
The Edwards E 2 M 2 has an NW25 inlet port with an adaptor flange. An NW25 centring ring and O-ring are supplied with the pump.[2]
What accessories are available for the Edwards E 2 M 2?
Accessories include an inlet catchpot, inlet dust filter, inlet desiccant trap, inlet chemical trap, solenoid-operated gas-ballast control valve, foreline trap, solenoid-operated pipeline valve, outlet mist filter, oil drain extension, vibration isolators, pump inlet adaptor, flexible bellows, and pump outlet adaptor.[2]
