Description of Products

1) This VF constant pressure low-power water pump inverter can achieve reduced flow by providing variable speed pump operation. This results in reduced system pressure and operation near the pump's best efficiency Point. In addition, maintenance costs might be reduced. This article will discuss the energy savings potential of variable frequency drives followed by a brief description of the operation and relative benefits of VFDs.
2) With LCD screen display, the interface of this low-power water pump inverter is easy to operate, no need of professionals to test or maintain.
3) This Constant pressure low-power water pump inverter supply system makes the life enjoyable, meanwhile improves the quality of life.
4) Electrical and hydraulic pump protection, automatic recovery after power failure, flexible installation either directly on a water Pump motors
