E1M18 PFPE

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 E1M18 and E2M18 pumps are direct drive, sliding vane pumps. The pump is oil sealed and designed for reliable, long-term operation. 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 exhaust flanges rather than the Nozzle that is supplied as standard with hydrocarbon pumps.

Fomblin® must be purchased separately for PFPE pumps

Features and Benefits

• The pump is configured for use with PFPE fluids.
• 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.
• Pressure die cast oil box with integral oil seals prevents oil leaks.
• Gas ballast valve for large water vapour handling capacity.
• Externally approved to EN61010, CSA, C22.2 and UL61010.
• Large O-ring sealed oil sight glass allows oil condition and level to be easily inspected.

Applications

• Pumping gas mixtures that contain more than 25% oxygen
• Where gas species being pumped causes the rapid breakdown of conventional hydrocarbon oils.
