Structure and characteristics

The body of motor and pump is made of hard cast iron for long-lasting durability.

Greatly increased maximum submersion depth due to mechanical seal resistant to high pressure.

The pump can be only partially immersed, with hydraulic part under motor and motor cooled by pumped water for safe operation. The top discharge design maximize the utilization of space. Hermetically sealed motor equipped with built-in thermal protection. Seal pressure relief ports is incorporated to prevent the pumping pressure from applying to the shaft seal.

The back-to-back design of the double impeller greatly reduces the axial force of the pump and improves the service life of the bearing.

Discharge 50mm(2'') to 150mm(6''), motor 3.0kW (4.0HP) to 150 kW (200HP).

Motor is dry type submersible induction motor (2 poles).
