4HS “H” pumps are equipped with a helical rotor that moves within a double-helix rubber stator.
The rotor is made of AISI 304 stainless steel and coated with a hard chrome surface.
During operation, the rotor moves on the rubber surface and is lubricated by the pumped water.
The flow rate is directly proportional to the pump speed while the pressure supplied is kept almost constant.
In this way, unlike a centrifugal pump, the helical rotor pump provides high head even at low rpm, ensuring water on surface even with very low available power or low solar irradiation.
In addition, the helical rotor pumps feature higher hydraulic efficiency than centrifugal pumps having the same flow. This saves in the number of solar panels necessary for the application.
