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)
