Working Principle of an LPG Pump

An LPG pump is a centrifugal pump that uses centrifugal force to extract liquefied petroleum gas (LPG) from a container and deliver it to the point of refueling. LPG is gaseous at normal pressure, but it liquefies after compression and cooling. Therefore, LPG pumps need to be capable of high pressure and low temperature operation to ensure efficient delivery and refueling of LPG.
