Double Pump Constant Pressure Water Supply System
2HP/1.5KW,3PH 380V,double pump,8m3/h(1pump,4m3/h),IN/OUT DN50

(1)Intelligent Constant Pressure Water Supply

(2)small in size, can carry-on installed in the pump.

(3)Set the pressure on the controller directly, constant pressure fully automatic operation.

(4)the signal can choose a variety of pressure: pressure sensors, transimissialbe pressure gauge,electrical contact pressure gauge.

(5) multi-pump control linkage with the turn of automatic pump function between the two pump only a communication line to connect, share the pressure signal.

(6) with a soft start and soft stop function. Avoid water hammer effect and impact on power grids. Double-pump can be set to control the rotation to rest, to extend the life of pumps and electrical accessories.

(7) unattended, when the call after power, water pumps start automatically, constant pressure control (this feature is optional).

(8) automatic fault detection, such as the water pressure is too high, too low, too low water level alarm, communications failures, and so on.

(9) a full range of motor protection features such as: electrical overload, short circuit, open circuit, overheat and over-voltage and low voltage protection, and so on.

(10) energy efficient, than the average of 30% of the secondary power supply 60%.

 

(11) double-pump can be linked, no auxiliary pump, auxiliary pump in a dormant state in peacetime, when the auxiliary pump water during the height of the peak automatically add water, high capacity utilization.
