Edwards 18 Vacuum Pump E2M18

Edwards 18 Vacuum Pump E2M18

EM Series pumps are rugged, mechanical oil-sealed pumps with speeds ranging from 0.7 to 28 m3/hr depending on model size and stage. Compact and quiet, they feature advanced lubrication circuits, high reliability, and accessories to suit your specific application needs.

    Quiet Operation:     Better Working Environment
    Reliable Performance:     Proven in a range of laboratory and industrial applications
    Free standing unit and compact design:     Flexibility of use
    Gas ballast valve:     Large vapour handling capacity

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.

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
