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.
SUMMAG Solar MP MOTOR
The 4HS MP pumps are equipped with the SUMMAG Solar MP motor with permanent magnets. The rotor utilizes Neodymium magnets coated with thin layers of Copper and Nickel, ensuring not only superior magnetic performance but also greater reliability and durability over time. In addition to high efficiency, there is high starting torque to move the pump under low irradiance conditions.
The integrated inverter module converts solar energy into electrical energy to efficiently drive the motor. Simultaneously, it adjusts the pump speed based on the available irradiance, maximizing the extracted power (MPPT). All protections, such as overcurrent, over temperature, and lack of water, are integrated on the pump board.”
