The 4” WPS-®CP pump is fitted with a three phase 230V Well Pumps motor. The 4” WPS®-CP controller needs a single-phase supply and stransforms it to a three-phase current to the motor. The controller is equipped with a frequency drive and performs a constant pressure of the flow through a variable speed of the pump. As a consequence, the pump can be set to operate any duty point in the range between the pump min. and max. performance curves. In case a pump fault, an alarm will be indicated on the LCD screen of the 4” WPS®-CP controller.
