The INTEWA pumping and water control unit PROFI comprises an integrated receiver tank, a double-pump booster system with self-priming multistage horizontal centrifugal pump, an alternating start-up and the electronic control system - all mounted in a housing made of powder-coated sheet steel. The control system constantly monitors the levels in the collection tank and the receiver tank. It includes: 4-line LCD display, operating hours counter for each pump, pressure display of the double pump system, level display of the collecting tank, potential-free fault indicators, RS 232 interface for all common building management systems.

The feeder pump in the collection tank automatically delivers water to the supply tank of the pumping and water station as required. In the event of a water shortage or manual switchover, drinking water is automatically fed into the storage tank as required in accordance with DIN EN 1717. In addition, the solenoid valve is activated regularly to prevent stagnation in the drinking water line. The system is largely self-operating. Only a few manual operations and adjustments are necessary.
