Cryogenic pump is a special type of centrifugal pump used in industries to pump low-temperature liquids and coolants. It is made up of special elastomers and is hermetically sealed to withstand low temperatures and avoid heat leakage. These pumps consist of one or more impellers and a diffuser. Velocity inside a cryogenic pump is converted into pressure through diffusion process. The cryogenic pump designing technology has uniquely clubbed technological vacuum considerations and cryogenic aspects. They are used for refrigeration purposes with the help of cryogenic gases such as liquid nitrogen, argon, and others. They provide have safety against power breakdown, as they do not require electric supply with liquid cryogens. The emergence of cryogenic pumps has reduced carbon emission problems. Moreover, properties such as higher isentropic efficiency, radial force balance, minimal maintenance, reliability, no shaft seal & bearings problems, and high safety levels have made them ideal for industrial use.
