Product details

Product Overview:

The WQP series stainless steel submersible pump has significant energy-saving effects, anti winding, non clogging, automatic installation, and automatic control. Stainless steel submersible pumps have unique effects in transporting solid particles and long fiber waste.

The WQP series stainless steel submersible pump is suitable for industries such as chemical, petroleum, pharmaceutical, mining, paper industry, cement plant, steel plant, power plant, coal chemical industry, as well as urban sewage treatment plant drainage system, municipal engineering, construction sites and other industries to transport granular sewage and waste. It can also be used to pump clean water and corrosive media.

The numbering method for WQP series stainless steel submersible pumps:

Characteristics of WQP series stainless steel submersible pump:

① The stainless steel submersible pump adopts a unique single blade or double blade impeller structure, which greatly improves the ability of pollutants to pass through. It can effectively pass through fiber materials with a diameter of 5 times the pump diameter and solid particles with a diameter of about 50% of the pump diameter.
② The mechanical seal adopts a new type of hard and corrosion-resistant tungsten carbide material, and the seal is improved to a double end face seal, allowing it to operate in the oil chamber for a long time, which can ensure the safe and continuous operation of the pump for more than 8000 hours.
③ The stainless steel submersible pump has a compact overall structure, small volume, low noise, significant energy-saving effect, easy maintenance, no need to build a pump room, and can work underwater, greatly reducing project costs.
④ The sealed oil chamber of the stainless steel submersible pump is equipped with high-precision anti-interference water leakage detection sensors, and thermal sensitive elements are embedded in the stator winding to provide absolute protection for the pump motor.
⑤ According to user needs, a fully automatic safety protection control cabinet can be equipped to provide absolute protection against pump leakage, electric leakage, overload, and overheating, improving the safety and reliability of the product.
⑥ The float switch can automatically control the start and stop of the stainless steel submersible pump according to the required liquid changes, without the need for special supervision, making the use of stainless steel submersible pumps extremely convenient.
⑦ A dual rail automatic coupling installation system can be equipped according to user needs, which brings great convenience to the installation and maintenance of stainless steel submersible pumps, and people do not have to enter the sewage pit for this.
⑧ Stainless steel submersible pumps can be used within the full head range while ensuring that the motor does not overload.
⑨ There are two different installation methods, fixed automatic coupling installation system and mobile free installation system.
