Classification of pumps USA Standard

Devices for pressure transfer of liquids are divided into species and varieties on various grounds, such as the principle of action and design. Such a feature form the basis for the classification provided in the USA Standard (ASTM 17389-72). AN can also be divided into 2 groups: the pumps, machines, actuated by motors and pumps, devices that operate at the expense of other energy sources and have no moving working parts. Pump machines are lobed (centrifugal, axial, vortex), reciprocating, rotary (gear, rotatory, plate, screw, etc.). K-pump apparatuses include jet (liquid-liquid and gas-liquid), gas-lift (including airlift), a propellant (including steam and gas), hydraulic rams, magnetohydrodynamic pumps, etc.
