The Goulds 5GBS0514G4 is a 1/2 HP, 115-230V single-phase multi-stage centrifugal booster pump from Xylem’s Goulds Water Technology GB series. This 7-stage, stainless steel pump is rated for 5 GPM at its best efficiency point, delivering approximately 150 ft. (about 65 PSI) of total dynamic head at that flow. The GB series’ stacked-impeller multistage design produces steady, quiet, vibration-free high-pressure output from a compact, horizontally close-coupled body.
