Many friends in the choice of pipeline pump products will ask the choice of vertical pipeline pump, pipe centrifugal pump or horizontal pipeline pump. The so-called rational selection of pumps, is to comprehensively consider the pump unit and pumping station investment and operating costs and other comprehensive technical and economic indicators, to make it in line with economic, security and applicable principles. Specifically, there are the following aspects: 1. Flow and lift requirements must be met, ie requiring the pump operating point (the intersection of the device characteristic curve and the pump performance curve) to always be maintained in the high-efficiency range operation, so that both mechanical and mechanical damage is not easy to damage. 2. The selected pump should not only small size, light weight, low cost, but also have good characteristics and high efficiency. 3. Has good anti-cavitation performance, so that both to reduce the depth of excavation of the pump room, but also to pump cavitation, smooth operation, long life. 4. According to the selected pump built pumping station, less investment, low operating costs. More keyword search: Pipeline pump
