WQ/JYWQ
Submersible electric sewage pump (Type B 7.5KW-90KW)

Product Overview:

The new WQ submersible sewage pump newly launched by Lulin Pump is developed in conjunction with the National Pump and System Center of Jiangsu University. It has absorbed the advantages of similar products at home and abroad, and has integrated the use experience of Lulin's products in the market for many years. It has been comprehensively optimized in hydraulic model, mechanical structure and seal, with higher lift, smaller floor area, high efficiency, energy saving and strong reliability; Simplified structure, easier disassembly, maintenance, and control, more economical and practical: diverse installation methods, simplified pump stations, and investment savings.

Main purpose:

The WQ new type submersible sewage pump is mainly used in municipal engineering, building construction, industrial sewage and sewage treatment occasions, to discharge sewage, wastewater, and rainwater containing solids and short fibers.

WQ pollution potential advantages:

1. The innovative design concept of high-efficiency and overload free hydraulic model, while taking into account the throughput capacity of sewage pumps, completely solves the worries of water pump operation. The technical characteristics of the overload free hydraulic model are that the maximum power point occurs in the high-efficiency zone, running smoothly, and without vibration.
2. The material of the pump head mechanical seal is made of silicon carbide to tungsten carbide, providing maximum wear resistance and longer service life of the mechanical seal; The motor end adopts double-sided sealing to improve the sealing effect.
