At the recent NPE2012 show in Orlando, Fla., Industrial gas supplier Linde North America, Murray Hill, N.J., showed off a new liquid-nitrogen pressure booster for gas-assist injection. The Presus N10 high-pressure liquid pump can boost nitrogen pressure to 4500 psi (300 bar) and delivers flow rates up to 4600 scf/hr, at least five times higher than the best gas compressors and consuming up to 90% less energy, Linde states. The pump also runs oil-free, which eliminates the risk of contaminating molded parts and saves on maintenance.
