E1M18 PFPE - EM Pumps (Small)
The E1M18 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

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.
