Pumps – How industrial components work
A pump is a device that moves fluids (liquids or gases) or sometimes sludge by mechanical action, typically by converting electrical energy into hydraulic energy. Pumps can be divided into three main groups based on the method they use to move fluid: direct delivery, positive displacement and gravity pumps
Pumps operate through a specific mechanism (typically reciprocating or rotary mechanism) and consume energy to perform mechanical work in transporting fluid. Pumps operate on a variety of power sources, including manual operation, electricity, motors or wind power, and are available in many sizes, from microscopic for medical applications to large industrial pumps.
Mechanical pumps are used in a variety of applications, such as pumping water from wells, aquarium filtration, pond filtration and aeration, in the automotive industry for water cooling and fuel injection, in the energy industry for the production of oil and natural gas, or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in the development and production of drugs and as artificial substitutes for body parts, particularly the artificial heart and penile implants.
When a casing contains only one rotating impeller, it is called a single-stage pump. When a casing contains two or more rotating impellers, it is called a two-stage or multi-stage pump.
