Centrifugal pumps

To appreciate what a huge significance devices such as pumps in the life of mankind, we must try to understand the figure, which indicates the amount of energy consumed on the planet. The value expressed by this figure - 20%. That is, the fifth of the total produced by hydro, thermal and nuclear power stations of electricity in the world, goes to work the pumps.
The principle on which the pump is not working very much, but there are a large number of groups. For example, centrifugal pumps divided into 18.
The main parameters of the pump efficiency is the amount of the conveyed fluid in 60 seconds, the pressure of which it is able to develop and capacity. From these figures the pump efficiency is calculated. There is a division of pumps for use. This industrial pumps and domestic. The pumps used in the home, the work performed in the field of water used in heating systems, sewerage systems. In industry pumps are busy so tightly that list their specialization is extremely difficult. This, and the supply of various liquid media, and the creation of high-pressure fluid to wash, work in the food industry, agriculture, medicine, for example for the creation of artificial blood circulation or ventilation and perform many other tasks.
