Heavy-Duty Sliding Vane Pumps

March 17, 2017

Called the market’s only alignment-free reduced speed positive displacement pumps GNX and GNXH Series Sliding Vane Pumps are designed to handle a wide range of non-corrosive, non-abrasive industrial liquids and petroleum products.


Manufactured with a larger operating range than competitive designs, pumps offer higher flows and higher pressure. These pumps are available with a robust, commercial-grade gear reducer with more 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, they are the only alignment-free pumps that can dry run without damage during self-priming and line stripping.
