Blackmer extends its GNX Series

Blackmer, part of PSG, a Dover company, has announces that its GNX Series Sliding Vane pumps are now available in 3-inch and 4-inch models.

The GNX Series pumps are alignment-free reduced-speed positive displacement pump and have been designed for the transfer of non-corrosive, non-abrasive industrial and petroleum products for both portable and stationary applications.

Originally launched in 2017 in 2-inch and 2.5-inch models, Blackmer GNX Series heavy-duty sliding vane pumps include the features of Blackmer legacy GX Series pumps but also incorporate a commercial-grade, single-stage gearbox, motor and baseplate.

The 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 maintenance. The 2-inch and 2.5-inch models have aluminum gearboxes and the new 3-inch and 4-inch models have 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).
