E1M18 PFPE
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.
