Axial Positive Displacement Pump

Giant Pumps' GX Series are made in America and can be mounted vertically or horizontally. This pump has the ability to be powered by a gas engine or an electric motor. Integrated with the pump is a thermal unloader and thermal relief valve. Valves are made using Delrin. 

We recommend a 1.15 service factor be specified when selecting an electric motor as the power source. To compute specific pump horsepower requirements, use the following formulas:

Electric HP = (GPM X PSI)/1450

Gas HP = (GPM X PSI)/1100

*Engine power varies based on horizontal or vertical orientation, as well as by makes and models from each manufacturer.
