FLOWJET Chlorine Water Spray Pump High Flow Pump Diaphragm Pump KFL-500 Series DC Pump Electric Pump12/24/36/60/72V 500W 50LPM 95PSI

Intelligent pressure switch: control the pressure of the water pump, the water pump stops working when the pressure exceeds the pressure, and the water pump works automatically when the pressure is lower than the start pressure.

Imported super wear-resistant pfa film is installed at the bottom of the diaphragm, which can more effectively extend the life of the diaphragm.

Four carbon brushes The water pump is more powerful, the motor has a longer service life, and the effective use time of carbon brushes is 2000 hours.

The built-in centrifugal cooling fan can quickly take away the heat of the motor, so that the pump can work continuously for a long time.

Four magnet tiles, stronger magnetism and greater torque. The power of the pump is stronger.

The motor adopts pure copper enameled wire with high temperature resistance and high insulation grade, which has stronger power and longer service life.
