Small variable frequency water supply unit. When water is used, when the pipe pressure drops to the ON value of the pressure switch, the water pump automatically starts to pressurize and deliver water; when water is stopped, when the pipe pressure reaches the OFF value of the pressure switch, the water pump automatically shuts down.

 

Uses of small frequency conversion water supply unit: apartment, house, villa water supply, factory water supply, water supply system, drinking water system, RO water treatment, market, motel, SPA.

 

Applicable liquid: clean water without impurities, clean, thin and non-corrosive neutral liquid.

 

Conditions of Use:   

    Ambient temperature: Max.+40℃

    Liquid temperature: +2℃～+90℃

    Inlet pressure: set value

 

Product description: The motor starts smoothly when water is used. The inverter senses the water pressure based on the feedback of the pressure sensor, and then controls the motor's operating frequency, steplessly changing to reach the speed, and the water pressure is stably maintained at the pressure setting value.

 

Constant pressure and voltage stabilization: The pressure will not be higher than the pressure setting value when in use, and the water supply will still maintain a constant pressure when the water consumption exceeds the constant pressure range.

No water and power off: When the water source is without water, the pump will automatically cut off water, and try to start by itself until the normal water supply.

Water stop and stop: When the water is stopped, the microcomputer automatically detects the return and controls the motor to decelerate and stop.

Leak detection compensation: The microcomputer automatically detects and runs the water pump to compensate the pressure to the set value.

Pressure difference switch; when the pressure transmitter function is abnormal, it can be switched to the pressure difference function to avoid no water available.
