Reduced-Speed, Positive-Displacement Pumps
The GNX Series has been designed to optimize the transfer of noncorrosive, nonabrasive industrial and petroleum products for portable and stationary applications. The heavy-duty sliding-vane pumps include a single-stage gearbox, motor and baseplate. The 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 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” models have aluminum gearboxes while the 3 and 4” models have cast-iron gearboxes. The 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).
