The mechanical seal

With two or three mechanical seals. It is generally the first mechanical seal that contacted with water directly is carborundum sealed, the second and the third is generally graphite or carborundum.

The leakage protection

QZ, QH series pumps have leakage protection sensor. When the leakage happened in the oil room, motor or terminal box, the sensor sends out the alarm or shuts down the motor and record the trouble signal.

Overheated protector

There are overheated protecting devices in the submersible motor winding, when temperature exceeds the regulation, it would send out the signal or shut the motor down.

Direction

Seen above the electric motor, the impeller is rotating clockwise.

Application range

QZ series submersible axial-flow pump, QH series submersible mix-flow pump are widely used in industry and agriculture water transportation, city water supply, slight sewage water discharge and water transfer project.

Working conditions

Clear water under 50 degrees Centigrage and other liquid that the chemical and physical properties similar to water.
