ZW Self-Priming Sewage Pump - A versatile sewage pump that is self-priming, non-clogging, and suitable for submersible applications. The ZW self-priming sewage pump is designed to handle a wide range of wastewater, including solids, fibers, and sludge. It offers a flow rate of 8 to 400 m³/h, a head of 15 to 80 meters, and a power range of 1.5 to 55 kW.
Key Features of the ZW Self-Priming Sewage Pump Developed by our engineering team, this pump integrates advanced foreign technology with domestic conditions. It features an innovative impeller and pump body design, allowing it to operate without a foot valve while handling large particles and long fibers effectively. Known as a solid-liquid pump or impurity pump, its unique hydraulic design ensures smooth operation and high efficiency. The impeller is housed in a separate chamber connected to the pressure chamber, creating a strong axial vortex during rotation. This mechanism generates a vacuum at the inlet and lift at the outlet, enabling the pump to discharge impurities efficiently without clogging. The ZW self-priming sewage pump is ideal for municipal sewage systems, paper mills, textile factories, food processing plants, chemical industries, mining operations, and aquaculture. Its performance range includes flow rates from 8 to 800 m³/h, DN sizes from 25 to 300 mm, head from 15 to 80 meters, speed from 2900 to 1450 rpm, and motor power from 1.5 to 55 kW.
