How to Select Cryogenic pump?
1.Confirm medium: LNG / LN2 / LOX / LAr, medium determines material & sealing solution
2.Working temperature & saturation pressure, calculate NPSHr (critical factor for cryogenic pump selection)
3.Required flow rate & head, add 10~15% margin for pipeline loss
4.Installation type: submerged inside tank or horizontal surface mounted
5.Power supply & ex-proof requirement, indoor or outdoor installation
6.Control type: fixed speed / VFD, DCS remote signal feedback or not
7.Project standard: GB, ASME, CE for export
Send your working condition data, our engineer provides free selection proposal
