Sanjing started its history from developing reciprocating pumps in 2004. They are improved again and again through out the past decade, having become a very mature and successful product, favored by transnational gas companies: Linde, Messer, Praxair and other ASU plants in their gas filling projects. This kind of pump is mainly for cylinder filling of industrial gas at a range of high pressure from 150 bar to 250 bar, such as LOX, LIN, and LAr.
Benefits and feature:
1.Vacuum jacketed cold end minimizes heat leak and lowers liquid vaporization.
2.Stainless steel made cold end ensures the steady performance at cryogenic temperature.
3.Specially de-oiled process allows the units a safety when pumping oxygen.
4.Interlocking provides protections avoiding over pressure and low temperature.
LOX, LIN, and LAr.
