Nitrogen Pumping Services


PFS's mobile nitrogen pumping services use modern tandem trailers and bobtail pumper trucks. Operating independently from the diesel prime mover is a high-BTU heater for converting liquid nitrogen to gaseous nitrogen. A 2,000 to 3,000 -gallon vacuum-jacketed tank mounted on the truck or trailer supplies the liquid nitrogen to the cryogenic pumps.


PFS's mobile pumping equipment is capable of delivering gaseous nitrogen up to 8,000 psi, controlled temperatures from 35°F to 400 °F and single unit flow rates up to 740,000 scfh.

Units are outfitted with pressure and high/low temperature shut downs. Certified pressure relief valves custom set prior to each project is mounted on each system we are conducting work on to ensure over-pressurization of your equipment is not possible. 


Larger liquid nitrogen requirements are transported to the pumpers by our own transport fleet and liquid can be stored on location in kings or queens depending on the project needs.

PFS has strategic alliances with all the major liquid nitrogen providers.
