  Performance characteristics of ZW type self-priming sewage pump
  The ZW self-priming sewage pump was successfully developed by our engineering and technical personnel by absorbing foreign technology and combining it with the actual situation of China's electromechanical industry. This pump has a novel structure of impeller and pump body, which not only eliminates the need for a bottom valve like a typical self-priming pump, but also allows for larger particles and longer fibers, making it have a broad application market and development prospects.ZW type self-priming sewage pump, also known as solid-liquid pump or impurity pump. The hydraulic design of this series of pumps is that the impeller is enclosed in a separate impeller chamber, which is connected to a pressurized water chamber. When the impeller rotates, the liquid inside the pump generates a strong axial vortex, creating a vacuum at the inlet and a head at the outlet. Therefore, impurities can be discharged from the pressure chamber, so its flow channel is unobstructed, and its discharge effect is the same as other self-priming discharge pumps. The ZW self-priming sewage pump produced by our unit does not require the installation of a bottom valve like a general self-priming water pump, and can also suck and discharge sewage containing large solid particles, long fibers, sediments, waste impurities, feces treatment, and all engineering wastewater. Self suction sewage pumps can be widely used in industries such as municipal sewage engineering, light industry, papermaking, textile, food, chemical, electrical, petroleum, mining, and river pond aquaculture. Self suction sewage pump is currently an impurity pump used in China to pump solid particles, fibers, slurries, and mixed suspensions. Performance range of self-priming sewage pump: Flow rate Q: 8-800 m ³/h Self priming sewage pump diameter DN: 25-300mm Self priming sewage pump head H: 15-80m Self priming sewage pump speed N: 2900-1450r/min Self priming sewage pump motor power: 1.5-55kw
