4Inch Stainless Steel Submersible Borehole Water Pump 

Structure and Features

4ST stainless steel well submersible electric pump is a high-performance electric pump.

  • The material of the parts meets the environmental requirements of the

European Union. The parts in contact with water are made of 304 stainless steel or copper and other non-corroding materials. The motor cooling oil is food-grade mechanical oil that is harmless to the human body;

● The motor adopts high-grade all-copper enameled wire, and the insulation grade reaches Class F; the sealed cable is used to prevent oil and water leakage at the cable inlet; the bottom of the motor is equipped with a pressure regulating membrane, and the maximum diving depth is 120 meters;

● Overall floating impeller design, made of PPO, has excellent sand and wear resistance;

● A stainless steel check valve is installed in the water outlet chamber to prevent the impact of water hammer on the pump components; non-leakage valves can be used in non-frozen areas.

The non-return valve can prevent the water stored in the water pipe from flowing back, and can realize water discharge immediately after starting up;

● The outer diameter of the electric pump is less than 100mm, and the motor and the pump body are in a separate structure, which is convenient for maintenance and replacement;

● The electric pump is equipped with a special cable junction tube to ensure that the joints will never leak;

● The electric pump has been equipped with an intelligent pump controller, which can effectively avoid burning due to abnormal voltage, impeller stuck, and no water in the well.

It has the function of automatically controlling the running and stopping of the electric pump according to the water level of the water tower.
