  2. Hand pump - Wikipedia

    en.wikipedia.org/wiki/Hand_pump

    Suction is the vertical distance between the fluid to be pumped and the centre of the pump, while lift is the vertical distance between the pump and the delivery point. [4] The depth from which a hand pump will suck is limited by atmospheric pressure to an operating depth of less than 7 meters. [ 5 ]

  3. Pumpjack - Wikipedia

    en.wikipedia.org/wiki/Pumpjack

    A diagram of a pumpjack. A pumpjack is the overground drive for a reciprocating piston pump in an oil well. [1]It is used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface.

  4. Pump - Wikipedia

    en.wikipedia.org/wiki/Pump

    A small, electrically powered pump A large, electrically driven pump for waterworks near the Hengsteysee, Germany. A pump is a device that moves fluids (liquids or gases), or sometimes slurries, [1] by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy.

  6. Centrifugal pump - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_pump

    This pump type operates without a foot valve and without an evacuation device on the suction side. The pump has to be primed with the fluid to be handled prior to commissioning. Two-phase mixture is pumped until the suction line has been evacuated and the fluid level has been pushed into the front suction intake chamber by atmospheric pressure.

  7. Hydraulic pump - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_pump

    Fluid flow in an external gear 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 ...

  8. Pump inducer - Wikipedia

    en.wikipedia.org/wiki/Pump_inducer

    An inducer is the axial inlet portion of a centrifugal pump rotor, the function of which is to raise the inlet head by an amount sufficient to prevent significant cavitation in the following pump stage. [1] It is used in applications in which the inlet pressure of a pump is close to the vapor pressure of the pumped liquid.

  9. Progressing cavity pump - Wikipedia

    en.wikipedia.org/wiki/Progressing_cavity_pump

    A progressing cavity pump is a type of positive displacement pump and is also known as a progressive cavity pump, progg cavity pump, eccentric screw pump or cavity pump.It transfers fluid by means of the progress, through the pump, of a sequence of small, fixed shape, discrete cavities, as its rotor is turned.
