Products Feature

This variable frequency drive inverter is used especially for water pump, it adopts the industry leading technique SPWM and pressure transmission technique, detects actual pipeline pressure change and controls the rotation speed of the pump.
The operation of this device is very easy, all functions can be finished by parameters setting , no need any professional staffs to debug.
This VFD inverter is high-efficient , it can save water and electricity up to 20%~60% compared to traditional water supply system.
Soft starting and stopping, constant water pressure prolong the service life of the pipe Network and make the water usage comfortable and enjoyable.
The range voltage is wild, it can work stably in areas with large voltage fluctuation.
The installation is very easy with direct screw thread, it can be used different kinds of water pumps and thus reduce extra costs.
LED display makes it convenient and fast to check and set actual pressure values.

Application

Tap water booster system
Household and residential water supply system
Swimming pool water supply system
Commercial water supply system
Factory dormitory water supply system
Industrial water circulation system
Cooling water systems
Cold water circulation system
