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...

Cable selection 3”WPS® 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].
