Edwards EM Series (Large)

The E2M Two Stage Oil Sealed Rotary Vane Pump is the tried and tested solution for applications when better ultimate vacuum down to 10^-3 mbar is needed. Available in sizes from 40 to 275 m3h^-1 it features a robust design for reliable and stable high vacuum performance.

Features

Reliability: Reliable and stable process - effective lubrication even under high gas loads
Robust: No contamination of process - oil and air suck-back protection
Performance: Long and trouble free life - industrial roller bearings on drive shaft

Applications

Furnaces and metallurgy
Optical and display coating
Pharmaceutical freeze drying
Refrigeration and air conditioning system evacuation
Transformer and cable drying
Brake line evacuation
Industrial leak detection
Plasma Coating and Cleaning

Positive Pressure Oil Lubrication:

These pumps have a well-proven, positive pressure oil lubrication system developed by Edwards to ensure correct lubrication in all operating modes, particularly under high gas loads where oil starvation is a common problem with other pumps.

Integral oil pump ensures an adequate oil flow through the stator/rotor assembly at all times
Only clean degassed oil is supplied to the high vacuum stage on two stage pumps
System is much less dependent on correct oil levels in the reservoir than other pump designs
Pumps can operate with oil levels as low as 50–70% of the maximum fill level (NOT RECOMMENDED)
