Product Overview: submersible sewage pump, QW (WQ) type non-clog pump easy to use, versatile, without use of the conditions and scope limitations, especially suitable for frequently mobile or temporary emergencies occasions. It does not need a fixed installation, put on rubber tube connected to the tube, the pump to put underwater settle can but must be equipped with a safety control box, to ensure safety. ① enterprise units wastewater discharge. ② city sewage treatment plant discharge system. ③ subway, basement, air defense systems, drainage station. ④ hospitals, hotels, high-rise buildings, sewage discharge. ⑤ Residential sewage pumping station. (6) municipal engineering, construction sites in the dilute slurry of emissions. ⑦ water plant, water supply installations. ⑧ farm sewage discharge and rural farmland irrigation. ⑨ exploration and mining and water treatment equipment. ⑩ instead of man Tam, suction river mud. Conditions of use water temperature ≤ 60 ℃, liquid PH value of 4 to 10. ① unique single blade or double blade impeller structure, greatly increased dirt capacity, pump five times the diameter fiber material with diameter pump about 50% of the diameter of the solid particles. (2) mechanical seal anticorrosive hard tungsten carbide material, sealing improvements for double seal its long run in the oil chamber to enable safe continuous operation of more than 8,000 hours. (3) the overall structure of compact, small size, low noise, energy-saving effect is remarkable, easy maintenance, do not need to build pumping stations, to dive can work, greatly reduce the project cost. ④ the pump seal oil chamber is provided with a high-precision anti-jamming leaking detection sensor, and the stator winding thermal components embedded within the absolute protection of the pump motor. ⑤ equipped with automatic safety protection control cabinet, pump leakage, leakage, overload and over-temperature absolute protection, improve the safety and reliability of the product according to user needs. ⑥ float switch can change according to the desired solution to automatically control the starting and stopping of the pump without supervised and extremely easy to use. ⑦ automatic coupling installation system equipped with dual rails according to user needs, it is to install, repair a great convenience, people do not have to get into the sump. ⑧ full head within, and to ensure that the motor will not overload. ⑨ there are two different installation, the installation of fixed automatic coupling system, mobile free installation system.
