Application:

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.

Working medium:

LOX, LIN, and LAr.
