4 3”WPS® and 3”WPS®-CP pumps are suitable for domestic applications in intermittent operation: • Domestic water supply • Small waterworks • Irrigation • Tank applications • Pressure boosting • Sampling of monitoring wells Note: For other applications, please contact Well Pumps. 3”WPS®-CP 3”WPS®-CP pumps offer the following features: • Pump entirely made out of stainless steel and fits in 3” or larger drilled wells • Constant pressure with two set pressures possible • Capacity from 0.2 to 7m³/h and a maximum head of 190m • Motor rating up to 1,5kW, 140Hz • Single phase supply to the controller • Incorporated jam free check valve • Dry-running protection • High efficiency of pump and motor • Excellent resistance to wear • Soft start • Overvoltage and undervoltage protection • Overload protection • Overtemperature protection. • Variable speed • Second set-pressure possible The 3”WPS®-CP pump is fitted with a three phase 230V Well Pumps motor. The 3”WPS®-CP controller needs a single-phase supply and transforms 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 in any duty point in the range between the pump min. and max. performance curves. In case of a pump fault, an alarm will be indicated on the LCD screen of the 3”WPS®-CP controller. The 3”WPS®-CP pump is sold as a kit and consists of the following elements: • A 3” submersible pump WPS® entirely made of stainless steel. • A WPS® high speed submersible motor able to run at variable frequencies up to 140Hz. • A WPS®-CP constant pressure controller including a variable speed drive, a flow detection and a pressure sensor. • A pressure vessel of 8 liter, a valve and a pressure gauge.
