WQ seres national standard sewage pump, the motor is located at the top of the elecrlc pump, it is a single-phase or three phase asynchronous motor, A double -end face mechanical seal is used between the water pump and the motor, and an O* type rubber sealing ring is used for static sealing at each fixed stopper sealing point This serles of electrlc pumps has the advantages of compact structure, large flow, high fflclenay, and easy use. The mechanical seals of key parts are made of hard aly and high- quality sliono carbide, which have good corrosion resitance, leak prevention, and durabity. This seres of electric pumps is widely used for the discharge of sewage and waste In mundpal sewage treatment, construction projects. hotels, miners. ponds, printing and dyeing, paper making, textiles, and other places It is an ideal equipment for pumping sludge, ash sury, domestic wastewater, sewage, feces and urine, and containing short fibers, paper scraps, mud, and sand fixed partdes, fural drainage and imigation, and rtver pond dredging.
1.The working medium is corrosive clear water. The volume ratio of sand in the medium does not exceed 0.10%, and the partide sie is not more than 0.20mm.
2.The medium temperature does not exceed 40C, and the pH value of the medium is between 6.5-8.5.
3.The eletric pump should be used within the use range near the rated head. The electric pump is fully immersed in water for use. The diving depth should not exceed 3m, and the deepest should not exceed 5m.
4.The electric pump is above 0.5m from the bottom of the water, but it cannot sink into the mud and sand.
5.The frequency of the electric pump is 50Hz, the single- phase voltage is 220V, and the three phase is 380V. The voltage fluctuation range is 09-1.1 times of the rated value.
