Features and Benefits
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.
Full height O ring sealed oil sight glass for easy checking of oil level and condition.
Large sight glass and operating oil range.
IE3 energy efficient 3 phase motor used with E2M2
Each EM pump is supplied with 1 litre of Ultragrade 19 oil, O ring and centering ring, two Allen keys and spares seal for oil drain and filter plugs. For PFPE prepared FX pumps Fomblin® to be ordered separately.
You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass. An oil filler-plug is fitted to the top of the oil box. The pump has an oil drain-plug to allow either gravity oil drain or pressure oil drain.
