Resined and incapsulated stator made of stainless steel AISI 304. Water cooled rotor. Kingsbury thrust bearing.
The Wilo-Actun OPTI HS is equipped with a helical rotor that moves within a double helix rubber stator. The rotor is made of AISI 316 stainless steel and coated with a hard chrome surface. During operation, the rotor moves on the rubber surface and it’ s lubricated by the pumped water. The flow rate is directly proportional to 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 irradiation. In addition, the helical rotor pumps feature higher hydraulic efficiency than centrifugal pumps of same flow. This saves in the number of PV panels necessary for the application. Permanent magnets motor The Wilo-Actun OPTI HS is equipped with AC permanent magnets motor. The rotor uses Neodymium magnets coated with thin layers of Copper and Nickel, to ensure, in addition to superior magnetic performance, greater reliability and durability. High motor efficiency and high starting torque make pump moving even in low light conditions. The integrated inverter module realizes the conversion from DC energy into useful electrical energy to drive the engine efficiently and, at the same time, adjusts the pump speed in relation to available irradiation, maximizing the power extracted (MPPT). Over-current, over-temperature, lack of water protections are integrated on-board.
