Pumps are categorized according to the way they build up the pressure.

Pumps with reciprocating displacement

Piston pump - inline-injection pump (Diesel engine)
Piston pump - acceleration pump (carburetor)
Axial piston pump - air conditioner compressor

Membrane pump - carburetor (petrol engine)
Membrane pump - accelerator pump (carburetor)
Pump injectors - Diesel injection

Pumps with rotary displacement

Roots charger - supercharging
Rotary vane pump - petrol injection
Vane pump - distributor injection pump
Double-action vane pump of the hydraulic power-steering
Gear pump and rotary pump - lubrication
Gear wheel pump (Common Rail)
Barrier-vane pump (pump jet)

Flow-distribution pumps

Peripheral pump - fuel distribution
Cooling pump - liquid cooling
Turbo charger

Pumps for liquids have been around for a long time, as water-wheels for 3000 years and as worm-screws, not quite that long. One distinguishes between displacement- and flow-distribution pumps. Displacement pumps move liquids by changing the volume and the respective controlled opening and closing of of inlets and outputs. The volume can be changed either by reciprocal or the rotating displacement pump.

Flow-distribution pumps, as opposed to displacement pumps, are more sensitive to substances containing gaseous inclusions. Basically, they are also not self-priming, unless they are fed. They also cannot, however briefly, transport gases. Therefore, they mostly provide a more even delivery-flow. Indeed, the displacement pumps are responsible when higher pressures occur, very high pressures are possibly better handled by the reciprocal displacement pump. 04/12
