Products Feature
- This 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 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 prolongs the service life of the pipe network and make the water usage comfortable and enjoyable.
- The voltage application range is wide and it can work stably even in areas with large voltage fluctuations.
- The installation is very easy with direct screw thread, it can be used on different kinds of water pumps and thus reduce extra costs.
- Digital color screen to display content.

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
