Self priming pump is a widely used general mechanical equipment. It is widely used in petroleum, chemical industry, electric power metallurgy, mining, shipbuilding, light industry, agriculture, civil defense and other sectors, and plays an important role in the national economy. Pump power consumption accounts for more than 21% of the national power consumption. Therefore, reducing the energy consumption of the pump is of great significance to energy conservation. In recent years, China's pump industry has designed and developed a variety of efficient energy-saving products, which have played a positive role in reducing pump energy consumption.

The selection of self-priming pump mainly involves the data of working medium, characteristics of working medium, head, flow and ambient temperature. The proper self-priming pump not only works stably and has a long service life, but also saves costs for users to the maximum extent. However, in various fields of the national economy, due to unreasonable selection, many pumps operate unreasonably, with low efficiency, and waste a lot of energy.

Other pumps cannot be used at all, because the selection is unreasonable, or the use and maintenance costs increase, resulting in low economic benefits. It can be seen that reasonable selection of pumps is equally important for energy conservation. The so-called reasonable selection of water pump is to consider the investment, operation cost and other comprehensive technical and economic indicators of the pump unit and pump station, so as to make them conform to the principles of economy, safety and applicability.

Specifically, there are the following aspects:

The operating requirements of flow and head must be met, that is, the working point of the pump (the intersection point of the device characteristic curve and the pump performance curve) is always kept in the efficient interval operation, so as to save electric energy rather than damage the parts easily. The selected self-priming pump shall be small in size, light in weight, low in cost, good in performance and high in efficiency. It has good cavitation resistance, not only can reduce the excavation depth of the pump house, but also can make the self-priming pump produce cavitation, stable operation and long service life. The pump station is constructed according to the selected pump, with less investment and low operation cost.
