The QWP stainless steel explosion-proof submersible pump adopts a unique single-channel impeller and a hard alloy mechanical sealing device with two sets of special materials for dynamic sealing. The motor is separated by an oil chamber, no clogging, significant energy saving, and can convey sewage containing solid particles and fiber materials without clogging or winding. Stainless steel explosion-proof submersible pumps are suitable for conveying industrial wastewater and municipal domestic sewage. They can also be used as hydrophobic pumps, pulp pumps, over-filtration flushing condensation circulation pumps, irrigation pumps, etc., and can also be used for pumping clean water in sewage treatment occasions. And it is suitable for frequent movement or temporary emergency use. ZMJT052QWP series stainless steel explosion-proof submersible pump Product Features ① The unique single-vane or double-vane impeller structure is adopted, which greatly improves the ability of dirt to pass, and can effectively pass 5 times the fiber material of the pump caliber and solid particles with a diameter of about 50% of the pump caliber. ② The mechanical seal adopts a new type of hard and corrosion-resistant tungsten carbide material. At the same time, the seal is improved to a double end seal, so that it can operate in the oil chamber for a long time, and the pump can operate safely and continuously for more than 8,000 hours. ③ The overall structure is compact, small in size, low in noise, remarkable in energy saving effect, convenient maintenance, no need to build a pump room, it can work by diving into the water, greatly reducing the cost of the project. ④ The pump sealing oil chamber is equipped with a high-precision anti-interference leakage detection sensor, and a thermal element is embedded in the stator winding to protect the pump motor. ⑤ It can be equipped with a fully automatic safety protection control cabinet according to user needs to protect the pump from water leakage, electric leakage, overload and overtemperature, etc., to improve the safety and reliability of the product. ⑥ The float switch can automatically control the start and stop of the pump according to the required liquid change. It does not need to be supervised by a special person, and is very convenient to use. ⑦ It can be equipped with a double rail automatic coupling installation system according to user needs, which brings great convenience to installation and maintenance, and people do not have to enter the cesspit for this purpose. ⑧ It can be used in the full head range, and the motor is guaranteed not to be overloaded.
