Features and Benefits
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.
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 E2M28.
