Claimed to be the market’s only alignment free reduced speed positive displacement pumps, the Blackmer GNX and GNXH series pumps are designed to handle non-corrosive, non-abrasive industrial liquids and petroleum products. The pumps are available with a commercial-grade gear reducer with operating speeds that allows for precise flow selections. GNX and GNXH Series pumps are self-priming, and the self-adjusting vanes help maintain this capability. In addition, claims the manufacturer, they are the only alignment-free pumps that can dry run without damage during self-priming and line stripping

Larger sizes coming

This series is currently available in 2- and 2.5 in flanged port sizes. Larger 3- and 4 in flanged port sizes will be released later this year. Combined, these sizes provide flow capacities ranging from 20 to 500 gpm (76-1,893 L/min) at working pressures up to 175 psi (12.1 bar). Both 90 degree and 180 degree porting are standard. GNX and GNXH Series pumps are designed for both portable and stationary applications. Typical applications include fuel oils, lube oils, jet fuels, gasoline, edible oils and a variety of solvents and thinners.
