Product Introduction


1.Pumps can be plugged in and used without manual pressure setting.

2.Stepless Pressure Regulation-Water pump can adjust its starting pressure intelligently.
3.Intelligent Pressure Regulation-water Hydraulic Fluctuation Controller Intelligently Superposes Pipeline Pressure.
4.Installation is not limited by floor height 0-100m lift can be applied, equipped with self-priming pump, jet pump, centrifugal pump, deep well pump and other applications.
5.Water Absorption Delay Function-water Absorption will test the water source for 8 minutes.
6.Automatic monitoring of water shortage, if water shortage for 5minutesthe intelligent controller will stop the pump operation.
7.When the water pump is short of protection, the water pump will start automatically
8.High temperature resistance 120 degrees.
9.Lightning protection.
10.Pressure tank can eliminate the effect of water hammer and prolongle service life of pump motor.
11.Manual mode prevents frequent start-up caused pipeline leakage
