WQ Submersible Sewage Pump

I. Product Overview

The WQ series non-clogging submersible sewage pump is a new generation product developed by combining advanced foreign technology with the specific operational characteristics of domestic pumps. It features reduced energy consumption, anti-tangling and non-clogging capabilities, as well as automatic installation and control functions. It is exceptionally effective at handling media containing solid particles and long-fiber debris.

This series utilizes a unique impeller structure and a new type of mechanical seal, enabling efficient transport of fluids containing solids and long fibers. Unlike traditional designs, the impeller employs a single- or dual-channel configuration—resembling a curved pipe with a uniform cross-section—which ensures excellent flow characteristics. When paired with a well-designed volute casing, this results in high operating efficiency; furthermore, the impeller undergoes dynamic and static balancing tests to minimize vibration during operation.

II. Product Features

1. Features a unique single- or dual-vane impeller structure that significantly enhances debris-handling capacity, allowing for the effective passage of fibrous materials up to five times the pump inlet diameter and solid particles up to approximately 50% of the inlet diameter.

2. The mechanical seal utilizes a new, hard, corrosion-resistant tungsten-titanium material, ensuring safe, continuous pump operation for over 8,000 hours.

3. The unit features a compact, space-saving design with low noise levels and energy-efficient operation. It is easy to maintain and eliminates the need for a dedicated pump house, as it operates while submerged, thereby significantly reducing construction costs.

4. The sealed oil chamber is equipped with a high-precision, anti-interference leakage detection sensor, and thermal sensing elements are embedded in the stator windings to provide automatic motor protection.

5. A fully automatic control cabinet can be provided upon request to monitor for leakage, electrical faults, overload, and overheating, thereby enhancing product safety and reliability.

6. A float switch automatically controls pump startup and stop based on liquid level changes, eliminating the need for manual supervision and ensuring great convenience.

7. The WQ series can be equipped with a dual-rail automatic coupling installation system upon request, greatly simplifying installation and maintenance by eliminating the need for personnel to enter the sewage pit.

8. The pump can operate across its full head range without risking motor overload. 9. Two installation methods are available: a fixed automatic coupling installation system and a mobile free-standing installation system.

III. Main Applications

Suitable for transporting sewage and waste containing particles in industries such as chemicals, petroleum, pharmaceuticals, mining, papermaking, cement, steelmaking, power generation, and coal processing, as well as in municipal sewage treatment plant drainage systems, municipal engineering projects, and construction sites. It is also suitable for pumping clean water and corrosive media.
