  3. Comparison of pumps - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_pumps

    Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...

  4. Rotodynamic pump - Wikipedia

    en.wikipedia.org/wiki/Rotodynamic_pump

    A rotodynamic pump is a kinetic machine in which energy is continuously imparted to the pumped fluid by means of a rotating impeller, propeller, or rotor, in contrast to a positive-displacement pump in which a fluid is moved by trapping a fixed amount of fluid and forcing the trapped volume into the pump's discharge.

    Screw pumps – the shape of the internals of this pump is usually two screws turning against each other to pump the liquid; Rotary vane pumps; Hollow disc pumps (also known as eccentric disc pumps or hollow rotary disc pumps), similar to scroll compressors, these have an eccentric cylindrical rotor encased in a circular housing. As the rotor ...

  6. Hydraulic pump - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_pump

    A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a load at the pump outlet.

  7. Turbopump - Wikipedia

    en.wikipedia.org/wiki/Turbopump

    A turbopump is a propellant pump with two main components: a rotodynamic pump and a driving gas turbine, usually both mounted on the same shaft, or sometimes geared together. They were initially developed in Germany in the early 1940s. The purpose of a turbopump is to produce a high-pressure fluid for feeding a combustion chamber or other use ...
