circulation pumps HKS/U with “wet” rotor

There are two versions of circulation pumps HKS/U with “wet” rotor: single-speed and three-speed. Insulation class – H.
The pump is equipped with single-phase/three-phase electromotor with “wet” rotor.

The main speciality of “wet” type equipment is a position of impeller with rotor directly in working medium. At the same time electric part is safely protected and sealed with the help of metal cup, which separates stator and rotor.
The fact that rotor is constantly located in water ensures its continuous cooling and parts lubricating. Moreover it provides an opportunity to absorb almost all the vibration noises, what makes these pumps near-silent. This is exactly what has become one of the main reasons of such a great popularity of “wet” type equipment in the customized heating systems.

Technical characteristics:
- power connection 1x230 V and 3x400V, 50 Hz;
- production capacity up to 40 m3/h,
