Nitrogen Pumping Services


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


PFS's mobile pumping equipment is capable of delivering gaseous nitrogen up to 5,700 psi in a wide, controlled temperature range at flow rates up to 660,000 standard cubic feet per hour.

Units are outfitted with pressure and high/low temperature shut downs. 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 and our nitrogen pumping services handle the largest of projects throughout the US.

"PFS provided purging and leak testing for four phases of our plant turnaround, it was the first time we used them but I promise it wont be the last as long as I have a say so. They're one of those contractors that makes your job easier and it was apparent it wasn't their first rodeo" ~ Anonymous
