What Is a Gasoline Pump?
A gasoline pump is a device used to supply gasoline.
They are primarily employed at gas stations to refuel vehicles, where a motor moves a piston to pressurize gasoline from the tank. Equipped with a fuel nozzle, the pump allows manual fueling by pulling a lever.
The nozzle is fitted with a sensor that automatically stops fueling when the tank is full. When the nozzle’s tip is submerged in liquid, the internal pipe of the nozzle enters a vacuum state, triggering the sensor to stop the fuel supply.
There are also smaller electric pumps designed for refueling from drums, some of which are portable. However, pumps without explosion-proof structures should not be used for gasoline due to safety concerns.
