A gasoline pump or fuel dispenser is a machine at a filling station that is used to pump gasoline (petrol), diesel, or other types of liquid fuel into vehicles. Gasoline pumps are also known as bowsers or petrol bowsers (in Australia and South Africa), [2] [3] petrol pumps (in Commonwealth countries), or gas pumps (in North America).
It is similar to that of a piston pump, but the high-pressure seal is stationary while the smooth cylindrical plunger slides through the seal. Plunger-type pumps are often mounted on the side of the injection pump and driven by the camshaft. [4] These pumps usually run at a fuel pressure of 3,600–26,100 psi (250–1,800 bar). [3]
Pre-payment is the norm in the US and customers may typically pay either at the pump or inside the gas station. Modern stations have pay-at-the-pump functions: in most cases credit, debit, ATM cards, fuel cards and fleet cards are accepted. Occasionally a station will have a pay-at-the-pump-only period per day, when attendants are not present ...

In some impulse pumps the gas trapped in the liquid (usually water), is released and accumulated somewhere in the pump, creating a pressure that can push part of the liquid upwards. Conventional impulse pumps include: Hydraulic ram pumps – kinetic energy of a low-head water supply is stored temporarily in an air-bubble hydraulic accumulator ...
The pumps were built by Siemens at their facility in Stafford, England. [5] A single 66" diameter pump was installed at Del Rio, Texas in 1914. [10] This was constructed by the Humphrey Gas Pump Co. of Syracuse, NY, who had licensed the Humphrey patents. [5] A single Humphrey pump was installed at a Sewage works in Southend-on-Sea, England ...
A filling station attendant or gas station attendant (also known as a gas jockey in the US and Canada [1] [2]) is a worker at a full-service filling station who performs services other than accepting payment. Tasks usually include pumping fuel, cleaning windshields, and checking vehicle oil levels.
The size of the station and the number of compressors (pumps) varies, based on the diameter of the pipe and the volume of gas to be moved. Nevertheless, the basic components of a station are similar. Natural gas may move through a pipeline system typically at speeds of up to 25 mph (11.2 m/s), depending on pressures and pipeline diameters.
