Cryogenic liquified gases are stored and supplied at a temperature close to their boiling point so that any pressure drop or heat input usually causes partial evaporation and produces an indefinite quantity of gas.
Since reciprocating pumps are basically designed to deliver a single-phase liquid, the presence of gas entering the cylinder of a piston pump is the most common reason for pumping problems, such as reduced capacity, vibrations, unusual noise development and increased wear.
Therefore, when designing pumps and pumping systems any thermal leak sources and circumstances that produce pressure drop in the liquid flow must be avoided thoroughly in order to gain the best possible performance of a pump facility. Krytem’s cryogenic pump series are designed to meet specific application requirements such as:
