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

Features and benefits Dry-running protection 3”WPS® and 3”WPS®-CP pumps are protected against dry running. The 3”WPS®-CP controller is equipped with a flow sensor that at all times measures the pumped flow. As soon as this flow drops under a minimum value (Qmin is about 0,1m³/h), the pump will be stopped. Simultaneously, also the absorbed power of the motor is measured. A minimum value of this power ensures cut-out of the pump. Both these measurements ensure in case of lack of water in the borehole, a shutdown of the pump and thus preventing a burnout of the motor. The 3”WPS® motor includes...

Overtemperature protection The electronic unit of the 3”WPS® and 3”WPS®-CP controller has a built-in temperature sensor. The 3”WPS®-CP controller will cut out the pump when the temperature of the fluid rises over its limit of 55°C. The error code ‘Inverter Error’ will be mentioned on the display of the 3”WPS®-CP controller. When the temperature has dropped to 45°C, the motor is automatically restarted. The 3”WPS® motor will reduce the speed as soon as the internal temperature in the motor reaches 80°C. This way the absorbed amps and consequently the dissipated heat of the motor will be...

Submersible drop cable to the motor (single phase) The table below shows the maximum length of the submersible drop cable between the supply and the motor for the different cable sizes and motor powers. The cross-sections of the cable are calculated according to a 3% voltage drop (IEC 60364:2001). The pump will cut out if the supply voltage falls below 160 V. Maximum cable lenght [m].
