Sewage pump and water pump difference

Clear water pump is a centrifugal pump range, water pump structure and principle and the general centrifugal pump is the same. Ordinary water pumps are designed for maximum efficiency, that is, the water pump's hydraulic structure parameters are the best combination for maximum efficiency. Sewage pumps, such special requirements of the pump efficiency can not exceed the same period of the efficiency of the pump. The main reason that the water pump is pure water pump and the efficiency is lower than that of the water pump is that their overcurrent channel is widened. The decrease in efficiency is mainly related to the degree of broadening. Water pump runner widening is to prevent clogging. Sewage pumps are centrifugal pump range, structure and principle and the general centrifugal pump is the same. Clear water pump also has its own structural features, sewage pump lift is not high, due to debris in the sewage more, the gap between the impeller than the large water pump. Clear water pump prone fault, and the general centrifugal pump is also similar, because pumping sewage, so impeller wear faster. Sewage pump Sewage pump impeller than the water pump is simple, there is no retainer, so that will not live in the grass, there is a saw blade below the impeller, the water pump can be adjusted up and down, can thread, cloth pieces and extracted .
