Description
- Includes outlet mist filter Part# A462-33-000
- The EM range of oil-sealed rotary pumps – renowned for its high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour – has become the industry standard laboratory and light industrial applications.
- The E2M28 pump is a two-stage, direct drive, sliding vane pump. The pump is oil sealed and designed for reliable, long-term operation in both laboratory and industrial environments. 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.
- The pump is designed for reliable, long-term operation
- Thermal overload device prevents overheating (single phase only)
- The pump is a free-standing unit
- 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
- Easy to use controls
- Pressure die cast oil box with integral oil seals prevents oil leaks
- Gas ballast valve for large water vapour handling capacity
