ΠΕΡΙΓΡΑΦΗ

The EM range of oil-sealed rotary pumps - renowned for its high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapor - has become the industry standard for industry and laboratory 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. Supplied with: Ultragrade 19 oil, NW25 O-ring and centering ring, lifting plate.

Features & Benefits

• 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.

Applications

• Analytical instruments - LCMS
• Automotive Beam lines and high energy physics
• Centrifuges, ultra-high speed Coating
