Product Features of WQ Submersible Stainless Steel Sewage Pumps

The flow passage component adopts the unique design method, with wide high-efficency area, and full-lift (no overload) performance. The pump is able to be effectively and safely operated in a larger flow range.

Strong carrying capacity and large-channel clog-proof design of impellers can make the pump effectively deliver the liquid containing solid particles, impurities and macrofiber with the diameter of 6-125 mm.

The motor uses the sleeve-type external circulation cooling system, which means that the product may be reliably operated when it is above the liquid level or the dry-type installation is adopted.

The product is equipped with alarm & protection systems for water leakage, electric leakage, oil leakage, overload, voltage shortage and phase loss, as well as liquid level control systems, able to carry out the centralized control and effective protection for various operating states.

The automatic installation system is reasonable in design, with high intensity, flexible and convenient installation, and no need of constructing pump rooms so as to save the project cost.

Adopt the imported high-quality bearing and grease with high temperature resistance, so that the quick-wear part's service life is more than 10,000 hours.

Applications of WQ Submersible Stainless Steel Sewage Pumps

Mainly used for sewage sludge discharge of industries like municipal sewage treatment projects, industrial & mining enterprises, hospitals, hotels, restaurants, and building industry, also applicable to farm irrigation.
