WQ series centrifugal pumps are commonly used to provide stable flow delivery in industries such as chemical processing, pharmaceuticals, petroleum, mining, cement plants, and power generation. The ability of this equipment to handle high flow rates stems from targeted designs in the impeller, flow passages, and motor, enabling smooth, clog-free conveyance of particulate-laden wastewater and corrosive media found in cement applications. WQ vertical submersible sewage pumps feature a unique large-channel impeller design that offers a more open flow path compared to traditional closed impellers. This allows for the smooth passage of fluids containing large quantities of solid particles or fibers, significantly reducing flow resistance and the risk of clogging. The pump casing's volute undergoes specialized hydraulic calculations and design optimization, enabling efficient conversion of the high-velocity fluid's kinetic energy into pressure energy, while minimizing losses during fluid collection and discharge to maintain stable output even under high-flow conditions.
This pump employs cutting-edge technologies such as computational fluid dynamics to precisely simulate and iteratively optimize the entire flow path from the pump inlet to the outlet. The blade profiles, angles, and flow channel cross-sections are meticulously designed to minimize fluid impact, vortex formation, and friction losses within the pump, enabling more direct and efficient energy transfer. In other words, under identical power input, a greater proportion of energy is directed toward increasing fluid flow rather than being dissipated through internal losses.
To achieve high flow rates, the WQ series slurry pumps are equipped with powerful motors that ensure the impeller receives sufficient torque for high-speed rotation. This enables continuous pumping of large volumes of fluid, overcoming pipeline resistance and increasing head. The motor's internal winding insulation and cooling system design are reinforced for long-term continuous operation, guaranteeing the power source's endurance. Simultaneously, durable and reliable mechanical seals are crucial for ensuring stable delivery capacity. These pumps utilize high-quality mechanical seals to effectively prevent leakage of the conveyed medium, not only safeguarding flow rate integrity but also ensuring the pump operates stably over extended periods. This maintains long-term, stable high-flow output. WQ series sewage pumps feature clog-resistant wide-channel impellers, highly efficient hydraulic designs, and high-power direct-coupled motors. With these designs, the pumps deliver long-term stable performance even when handling high-flow tasks such as municipal sewage discharge, industrial wastewater treatment, and flood control and drainage.
