    en.wikipedia.org/wiki/High-density_solids_pump

    The most characteristic element of the transfer tube pump is S-shaped "transfer tube" installed inside the feed hopper, which connects the advancing piston to the outlet. In other words, the pump cylinder which is currently pushing the material is connected to the delivery line by the transfer tube, while the retracting (pulling) cylinder is ...

  4. Centrifugal pump - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_pump

    Warman centrifugal pump in a coal preparation plant application A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...

  5. 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 ...

  6. Drum pump - Wikipedia

    en.wikipedia.org/wiki/Drum_pump

    Drum pumps on barrels. Drum pump, barrel pump, and transfer pump refer to pumps that are used to empty barrels, tanks, IBCs and drums. [1] Many liquids used on manufacturing and processing plants are delivered in 100 or 200 litre barrels and are too heavy to tip to empty the liquids inside.

  7. Vacuum pump - Wikipedia

    en.wikipedia.org/wiki/Vacuum_pump

    Momentum transfer pumps, also called molecular pumps, use high-speed jets of dense fluid or high-speed rotating blades to knock gas molecules out of the chamber. Entrapment pumps capture gases in a solid or adsorbed state; this includes cryopumps, getters, and ion pumps. [14] [15] Positive displacement pumps are the most effective for low vacuums.
