<p><P>PROBLEM TO BE SOLVED: To provide a low temperature fluid boosting pump system that improves a state where a low temperature fluid boosting pump is operated at a low rotation speed and enhances pump suction efficiency. <P>SOLUTION: In the low temperature fluid boosting pump system for boosting a low-pressure LNG (low temperature fluid) introduced from an LNG tank, a plurality of piston pumps 21A-C for boosting the LNG are parallelly arranged. At least one of the piston pumps 21A-C includes a bypass flow path 30 to perform a recycle operation for a pumping flow rate when the flow rate is low. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
