LNG Cryogenic High Speed Centrifugal Pump 316L SS Vertical Design 35 M3/Hr Low NPSHr With Inducer
LNG Cryogenic Centrifugal Pump
,Low NPSHr Vertical Design
,316L SS High Speed Pump
Product Description
Purpose-built for liquefied natural gas and light hydrocarbon services at cryogenic temperatures, this high speed centrifugal pump integrates a low-NPSHr inducer and 316L stainless steel construction for maximum reliability in the most demanding cold-end applications. The vertical in-line design minimizes heat leak and simplifies cold box integration.
