Enhanced submersible sewage pump with sub cone cast iron sewage lifting pump

Submersible sewage pump can be installed in a movable or automatic coupling manner

Mobile installation: WQ submersible sewage pump can be installed with a flexible elbow hose on site, and the bottom of the pool is not fixed. It is generally used for small water pumps.

Automatic coupling installation:

The WQ submersible sewage pump is suitable for long-term fixed use scenarios and has the advantages of quick installation, easy detection and maintenance. The system uses a specially designed base, fixed at the bottom of the sewage pit, connected to the outlet pipe, and a matching support block installed on the top of the pool. The two are connected by a guide rod, and the water pump is connected to a specific bracket. It slides down along the guide rod to reach the base and automatically couples with it. Sealed and automatically detached when lifted.

Introduction to the Structure of Submersible Sewage Pump

The WQ type unobstructed submersible sewage pump consists of a motor and a pump, which are separated by an oil isolation chamber and mechanical seal components. It is an electromechanical integrated product, and the motor and pump share the same shaft (rotor). The entire length of the water pump is short and the structure is compact. Equipped with multiple protective devices to ensure safe and reliable operation of the pump. The main functions of its components are as follows:

Signal line 1: Equipped with a fully protected water pump control cabinet to protect the pump, including water leakage, phase failure, short circuit, overheating, motor overload, and other items.

Motor stator 8: adopts B-level or F-level insulation.

Leakage probe 11: This component is installed in the oil chamber. When the mechanical seal is damaged and water enters the oil chamber, the probe can send a signal to the control system to protect the pump.

Mechanical Seal 13: Adopting a dual channel series seal and using a new type of hard and corrosion-resistant tungsten carbide material, it has the characteristics of reliable sealing, wear resistance, and long service life.

Impeller 17: The impeller adopts a single or double channel structure, which has strong passing capacity and can pass large materials and fiber waste, reducing blockage and entanglement failures.

Pump body 15: Paired with the impeller, the pump has high efficiency.

Sealing ring 18: installed at the mouth ring of the pump body. When the impeller wears out the mouth ring due to operation, the sealing ring can be replaced to ensure that the pump operates at a better efficiency.
