The pump — the hydraulic machine transforming mechanical energy of the driving engine to energy of a stream of liquid, serving for movement and creation of a pressure of liquids of all types, mechanical mix of liquid with solid and colloidal substances or the liquefied gases. It is necessary to notice that cars for transfer and creation of a pressure of gases are allocated in separate groups and received the name of fans and compressors. The difference of pressure of liquid in the pump and the pipeline causes its movement.

Incomplete classification of pumps by the principle of action and design looks as follows:
impellerny (lamellar) pumps
lamellar (shiberny) pumps
Water ring pump
axial and plunger pumps
Radial and plunger pumps
centrifugal shnekovye (disk, osediagonalny) pumps
The present standard extends to the centrifugal borehole electric pump units with giving from 0,63 to 1000 m3/h and a pressure from 12 to 680 m (further units) intended for rising of water with the general mineralization (the dry rest) of no more than 1500 mg/l with a hydrogen indicator (rn) from 6,5 to 9,5 with a temperature up to 25 °C, with a mass fraction of solid mechanical impurity - no more than 0,01%, with the content of chlorides - no more than 350 mg/l, sulfates - no more than 500 mg/l, hydrogen sulfide - no more than 1,5 mg/l produced for general usage and for export of climatic modifications of Wu Yi of T in accordance with GOST 15150.
Requirements of the present standard are obligatory regarding giving, a pressure and efficiency, other requirements - recommended.
