Products Feature

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