Specific Pump Power (SPP) is a metric in fluid dynamics that quantifies the energy-efficiency of pump systems. It is a measure of the electric power that is needed to operate a pump (or collection of pumps), relative to the volume flow rate. It is not constant for a given pump, but changes with both flow rate and pump pressure.
The Pulsometer steam pump is a pistonless pump which was patented in 1872 [2] by American Charles Henry Hall. In 1875 a British engineer bought the patent rights of the Pulsometer [3] and it was introduced to the market soon thereafter. The invention was inspired by the Savery steam pump invented by Thomas Savery.
Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the discharge column (discharge head). A beam-type pumpjack converts the rotary motion of the motor (usually an electric motor ) to the vertical reciprocating motion necessary to drive the ...
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.

A pulser pump makes use of water that flows through pipes and an air chamber from an upper reservoir to a lower reservoir. The intake is a trompe, which uses water flow to pump air to a separation chamber; air trapped in the chamber then drives an airlift pump. The top of the pipe that connects the upper reservoir to the air chamber is ...
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 ...
A 0.75 HP bore-well submersible pump which had been used to pump groundwater One style of submersible pump for industrial use. Outlet pipe and electrical cable not connected. A submersible pump (or electric submersible pump (ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in ...
