WaCS variable speed pump controllers are the ideal solution for automatic on-demand water supply in multiple outlet applications

WaCS variable speed pump controllers are the ideal solution for automatic on-demand water supply in multiple outlet applications. Working on the inverter principle pump motor speed is varied with demand thus regulating pump output to a preset outlet pressure. This provides the following operational benefits:-


   Constant outlet pressure up to the pumps maximum capacity providing consistent, even supply.

   Up to 50% reduced energy consumption as pump output is matched to site demand.

   Silent operation without the start and stop pressure shocks of fixed speed systems.

   Elimination of pressure vessels.

   Eliminates starting current peaks.


The revolutionary WaCS controller is a technology leading control unit specially developed for all small scale water supply applications. It is installed in-line on the pump outlet, an in-built pressure sensor regulating the inverter which provides variable frequency power to the pump motor. Various models are available for a wide variety of pump applications, all offering the following advantages and features:-


    Simple to install and can be used for most types of pumps.

    Adjustable for outlet pressure and motor current.

    Flow switch provided for run dry protection.

    In-built protection for high and low voltage, motor overload and phase failure (three phase input supply).

    Provides for economical installations as piping is simplified and requirement for switches, control panels and pressure tanks is eliminated. 


Variable speed is the modern way to optimise automatic on-demand water supply and WaCS controllers are high performance products incorporating this technology. Together with their additional control features and simplified installation, they provide the best solution for multiple outlet demand installations.
