Edwards EM Series (Small)

E2M0.7 / 1.5

The E2M0.7 and E2M1.5 pumps are two-stage, direct drive, sliding vane pumps. The pump is oil-sealed and designed for reliable, long-term operation. The pump is a free-standing unit. The drive is provided through an Oldham coupling by a totally enclosed fan cooled single phase motor. The pump is well suited for scientific applications such as backing turbomolecular pumps and general laboratory applications.

Applications

Analytical instruments
Leak detectors, helium
Research and development
Backing turbomolecular pumps

Features and Benefits

E2M0.7 has very low sound level of 43dB(A)
The pump is designed for reliable, long-term operation
Compact dimensions
Low energy consumption
Low operating temperature will minimise the heat load on the equipment
The pump is a free-standing unit
The motors are totally enclosed and are cooled by the motor-cooling fan and protected by a thermal overload device
Full height O-ring sealed oil sight glass for easy checking of oil level and condition
Gas ballast valve for water vapour handling capacity
Approved to EN61010, CSA, C22.2 and UL61010

EM18 & EM 28

The EM range of oil-sealed rotary pumps - renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour - have become the industry standard for laboratory and light industrial applications. The pump is a freestanding unit with the drive provided through a flexible coupling by either a single-phase or three-phase (four pole) motor.

Applications

Analytical instruments
Leak detectors, helium
Research and development
Backing turbomolecular pumps
Automotive
Beam lines and high energy physics
Centrifuges, ultra-high speed
Coating

Features and Benefits

The pump is designed for reliable, long-term operation
Thermal overload device prevents overheating (single phase only)
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
Full height O ring sealed oil sight glass for easy checking of oil level and condition
Large sight glass and operating oil range
