In fact, every a pump is a machine that is used for moving liquid through a piping system and raising its pressure. Pumps can be also defined as machines using several energy transformations in order to increase the pressure of the fluid. The electricity is commonly used for powering an electric motor; however, there are some alternative forms of energy used to power the driver like fuel oil powering a diesel engine, high-pressure steam driving a steam turbine, high-pressure hydraulic fluid to power a hydraulic motor, and compressed air to drive an air motor. The present publication jas been dedicated to the pumps and covers following major aspects of pumping technology - introduction; hydraulics, selection, and curves; special hydraulic considerations; types and applications of centrifugal pumps; sealing systems; sealless pumps; life-cycle costs and energy conservation; special pump-related topics; installation, maintenance and operation; major pump suppliers in the US; conversion formulae.
