Variable frequency xonstant pressure pump:

Combine 8 PCS of pump in a water system

MODBUS communication mode control master and auxiliary control

Any pump as the master pump

One pressure sensor in the system is enough

Easy wiring and free to adjust

High accuracy of constant pressure: 0.3% rated pressure

Full valid pressure range of automatic sleep function

Automatically start and stop the water pump

Completely protection: Overload of motor, short circuit of motor, undervoltage, overvoltage, lack of water, low water lever, high water pressure, low water pressure

10-50% energy saving

Application: Water supply system without the water tower. Water supply system without pressure tank, non-negative pressure for water supply
