WQ Series Submersible Sewage Pump

Product  Outline

WQ series submersible sewage pump developed by Shanghai Liancheng has absorbed the advantages of similar products at home and abroad, and has been comprehensively optimized in hydraulic model, mechanical structure, sealing, cooling, protection and control. It has good performance in discharging solidified materials and preventing fiber winding, high efficiency and energy saving, and strong possibility. Equipped with a specially developed special control cabinet, it not only realizes automatic control, but also ensures the safe and reliable operation of the motor; Various installation methods simplify the pumping station and save investment.

Main Purpose

Submersible sewage pump is mainly used in municipal engineering, building construction, industrial sewage, sewage treatment and other industrial occasions. Discharge sewage, waste water, rainwater and urban domestic water with solid particles and various fibers.  

Structural Installation Instructions

1. Automatic coupling installation;

2. Fixed wet installation;

3. Fixed wet installation;

4. No installation mode, that is, the water pump does not need to be equipped with coupling device, fixed wet base and fixed dry base;

   If it is used to match the coupling device in the previous contract, the user should indicate:

   1. No coupling frame.
   2. Matching coupling frame;

5. From the suction port of the pump body, the impeller rotates counter clockwise.

Performance Range

• Flow range : 5～8000 m³/h

• Head range : 5～65 m

• Medium temperature : ≤40 ℃

• Diameter : 80～600 mm

• Speed：2950r/min  1450 r/min  980 r/min  740 r/min

Working Conditions

1. Medium temperature: ≤40℃, medium density: ≤ 1050kg/m, PH value in the range of 4 ~ 10, and solid content cannot exceed 2%;

2. The main parts of the pump are made of cast iron or ductile iron, which can only pump the medium with slight corrosion, but not the medium with strong corrosion or strong abrasive solid particles;

3. Minimum operating liquid level: see ▼ (with motor cooling system) or △ (without motor cooling system) in the installation dimension drawing;

4. The diameter of the solid in the medium should not be greater than the minimum size of the flow channel, and it is recommended to be less than 80% of the minimum size of the flow channel. See the "main parameters" of pumps of various specifications in the sample book for the size of flow channel. The length of medium fiber should not be greater than the discharge diameter of the pump.
