Description:
Part of the Iron Line of sliding vane pumps, these Blackmer® pumps are the market’s only alignment-free, reduced-speed positive displacement pumps. They are suited for both portable and stationary applications. GNX Series pumps include the proven features of Blackmer legacy GX Series pumps but take them to the next level with the incorporation of a commercial-grade, single-stage gearbox. This innovative new gearbox fits between the motor and pump and is held in place by a permanent dowelled connection that creates a structural link between the high-speed and low-speed sides of the system. This results in a pump that will not need to be realigned either at initial installation or following a maintenance procedure, resulting in improved peace of mind for the operator. The pre-grouted GNX composite baseplate adds additional value to the pump, gearbox and motor setup by providing unmatched surface flatness, significant vibration damping, and reduced installation costs.
The GNX and GNXH Series pumps are designed to handle a wide range of non-corrosive, clean industrial liquids and petroleum products and are available in 2-, 2.5-, 3-, and 4-in sizes. The GNX Series pumps have a 90° porting orientation and the GNXH Series pumps have a 180° porting orientation.
