Blackmer® Extends its Line of GNX Series Pumps

16 Jul 2019  |
Grand Rapids, MI – July 16, 2019 – Blackmer®, part of PSG®, a Dover company and a global leader in specialty pumps and reciprocating compressor technologies, is pleased to announce that its GNX Series Sliding Vane Pumps are now available in 3- and 4-inch models.

The market’s only alignment-free reduced-speed positive displacement pumps, the Blackmer GNX Series have been designed to optimize the transfer of non-corrosive, non-abrasive industrial and petroleum products for both portable and stationary applications.

Originally launched in 2017 in 2- and 2.5-inch models, Blackmer GNX Series heavy-duty sliding vane 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, motor and baseplate. 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 2- and 2.5-inch models have aluminum gearboxes while the new 3- and 4-inch models feature cast iron gearboxes.

GNX Series pumps provide flow capacities ranging from 7 to 500 gpm (25 to 1,893 L/min) at working pressures up to 175 psi (12.1 bar). They are also available with optional steel and composite baseplates. The pre-grouted composite baseplate adds additional value to the pump, gearbox and motor setup by providing unmatched surface flatness, significant vibration damping and reduced installation costs. GNX Series pumps have a 90° porting orientation and GNXH Series pumps have a 180° porting orientation. These pumps are available in a full range of motors from 1 to 50 hp.
