The Goulds 7GB and 10GB Booster Pumps are portable, horizontally configured multistage pumps used for residential and agricultural washdown, misting, evaporative cooling, spray systems, general boosting service, and general pumping operations. The multistage design also allows for pumping to high heads while simultaneously operating quietly and vibration free. The Goulds GB series Booster Pumps are designed for durability and corrosion resistance. The elements of each stage are particularly tough: the impeller and diffuser are made of glass filled engineered composite material while the bowl is 300 stainless steel rabbit lock for positive alignment with no gaskets required. A high pressure o-ring sealing can easily be disassembled for easy maintenance or repair. The motor is designed for continuous operation. The primary difference between the two classes is the best efficiency GPM for each (7 GPM for the 7GB series, 10 GPM for the 10GB series).
