Domestic Well Pump (3.5 Inch 3T)
The home well pump (3.5 inch 3T) consists of a multi-stage deep well pump, a three-phase (or single-phase) submersible motor, a rigid coupling and a shaft seal. The multistage pump is located on the top of the motor. The pump uses water to lubricate the guide bearing. The pump shaft is connected to the motor shaft via a coupling. A sand control valve is installed in the discharge chamber to prevent sand from entering when the pump is stopped. The motor shaft is double mechanically sealed (single or three phase). The starter is equipped with a thermal protector to ensure safe operation of the motor.
