DPC is Digital Pump Controller, which is easy to use, programmable device for
three phase pumps (DOL). It can be used to control the pumps from 1.5 to 16
Ampere.
APPLICATIONS:
DPC is very useful in water and wastewater applications, be it water transfer,
tank filling, tank emptying or even pressure boosting in Hydro-pneumatic
applications. It is ideal choice in residential, industrial or institutional segments
where water and energy conservation are of utmost importance.
