    Booster Systems

     We offer booster systems – DP pumps, which is an assembly on a diaphragm tank using DP make, specially developed MEGA controller (logic controller) control panel with up to 6 pumps with a Precharged diaphragm and a variable speed drive control panel. One pump will be on a variable speed drive and the rest on fixed speed.

    Application of booster systems:
    • Initially the variable speed pump start first and start pumping into the system. The pressure transmitter provide the signal to the variable speed drive through the PID controller.
    • A constant desired pressure shall be maintained by varying the speed of the motor proportioned to demand.
    • When consumption is more then variable speed pump starts to overload, and one fixed speed pump automatically cut in and the variable speed pump shall adjust speed to maintain a constant pressure.
    • If two pumps are working and pressure still continuous to fall.
    • The third pump automatically cut in and so on.
    • This booster system is suitable for applications with extreme capacity fluctuations.
