The cultural evolution of pumps and the development of various types of pumps

A pump is a machine that conveys liquids or increases their pressure. It transfers mechanical energy from a prime mover or other external source to the liquid, thereby increasing the liquid’s energy. Pumps are primarily used to convey liquids such as water, oils, acidic and alkaline solutions, emulsions, suspensions, and liquid metals; they can also handle mixtures of liquids and gases, as well as liquids containing suspended solids.
