DPC CSCR is Digital Pump Controller, which is easy to use, programmable device 

for single phase pump, which require both starting capacitor and running 

capacitor. It can be used to control the pumps from 0.37 to 2.2 kW rating.

 

 

 

 

DPC CSCR is very useful in water and wastewater applications, be it water 

transfer, tank  f illing, tank emptying or even pressure boosting in Hydro-pneu- 

matic applications. It is ideal choice in residential, industrial or institutional 

segments where water and energy conservation is of utmost importance.
