Product Features

·This pump has a self priming function, using high-quality bearings, stainless steel shafts, stainless steel pump body, rust free water, and never jamming.

·This pump adopts a permanent magnet variable frequency motor and intelligent chip drive control, which is energy-saving and efficient, saving 40%-70% electricity compared to conventional water pumps.

·This pump adopts high-precision pressure sensor and water flow switch dual control, which automatically starts and stops constant pressure water supply for more reliable.

·This pump adopts a wide voltage design. When the voltage is between 160V-260V, the water pump can operate normally and its performance remains unchanged.

·Adopting multi-mode control according to actual application scenarios, with powerful functions. Manual mode | Automatic mode 丨 Constant pressure mode | Water tower timed automatic water supply mode

·Multiple protection: water shortage protection 丨 locked rotor protection 丨 voltage anomaly protection 丨 over temperature protection 丨 anti freezing protection 丨 leakage prevention frequent start protection

·Display function: Fault display 丨 Running power display 丨 Running pressure and set pressure display 丨 Timing countdown display 丨 Running speed display


Application Occasions

When the pressure of household water is lower than the set pressure,this pump can automatically supply water at a constant pressure and shut down the faucet automatically.

Suitable for hotel and restaurant water supply,high-rise buildings and water towers water supply, solar energy, air energy water heater pressurized water supply,well or pond water absorption,industrial equipment pressurized water supply,garden irrigation and car washing,etc
