Liquid nitrogen pump is a kind of special equipment, it could make the low pressure liquid nitrogen transform into high pressure. Compared with others nitrogen generation equipments, the liquid nitrogen pump could produce higher pressure and displacement nitrogen, widely used in nitrogen fracturing, miscible displacement, natural gas pipeline purging, cooperate with the coiled tube, etc. The types of the liquid nitrogen pumps : LNP-90K/105、LNP-180K/105、LNP-360K/105、LNP-660K/105、LNP-740K/105、LNP-1000K/105. In skid-mounted, truck-mounted or trailer-mounted types.
