Filling Station Pump

a device installed at filling stations and designed to measure and deliver liquid fuel into the tanks of motor vehicles and other self-propelled machines or into storage containers for consumers. Electrically driven centrifugal and rotary pumps are used to supply large quantities of fuel; manual reciprocating or vane pumps are used to deliver small quantities of fuel. The fuel delivered is measured by measuring vessels or volume meters and is recorded by monitoring devices. Pumps may have manual or remote control or a combination of the two. In pumps with automatic control, the fuel is delivered only after a key, perforated card, token, or coin is inserted into the proper slot in the control panel.

The most common types of pumps have outputs of 5 to 40 l/min with a minimum fuel delivery of 2 l and a measurement accuracy of ±0.2–0.5 percent. The tip of the delivery hose and the pump equipment are electrically grounded.
