  In various fields of national economy at present, due to the unreasonable type selection, many of the running status of pump in the unreasonable operation efficiency is low, waste a lot of energy. And due to the unreasonable selection of pump, it was impossible to use, or use the maintenance cost increases, the economic benefit is low. Therefore, reasonable choose pump is of great significance to save energy. So-called reasonable selected pump, is to consider investment and operation cost of pump unit and pumping stations comprehensive technical and economic indexes, such as make it conform to the principle of economy, safety and applicable. In particular, has the following several aspects: must meet the requirements of the use of flow and head, which requires the operation condition of the pump point (device characteristic curves with the pump performance curve intersection) often remain within the range of efficient operation, save power and not easy attaint parts. The choice of the pump should not only small volume, light weight, cheap, and has good characteristics and higher efficiency. Has good resistance to cavitation performance, this can not only reduce the pump room of the excavation depth, and the water pump cavitation occurs, smooth operation, long service life. Built according to the selected pump pumping station, the project less investment, low operating cost.
