MH (55-110 kW)

High Head Dewatering Pump
MH (55-110 kW)
High Head Dewatering Pump MH (55-110 kW)

MH-series submersible pumps with a strong construction are designed to withstand the high pressure during deep well dewatering.

Motor and pump casing is made of rigid cast iron for long-lasting durability.

Maximum submersion depth is greatly increased due to special mechanical seal resistant to high pressure.

Motor is cooled by the pumped water for safe operation even in case the pump is operated continuously in semisubmerged condition.

Space saving design due to a top outlet.

Discharge from 150mm to 200mm, motor 55kW to 110kW. Pump is equipped with dry type submersible induction motor (2 poles).
