G2S - Vertical Sump Pump

For added simplicity, the entire series is based on the same hydraulics as our horizontal pumps and is covered with only two bearing frames. The basic G2S design consists of a pumping (wet) end, bearing frame, drive shaft, motor mounting bracket, top plate, and discharge piping. All models feature external impeller adjustment, bearings above the liquid surface, no mechanical seals to maintain, full compatibility with standard NEMA ‘C’ face motors, and some of the most efficient hydraulics in the industry.

Available in 1.0 foot increments for sump depths from 4 feet to 22 feet, the G2S is offered with carbon lineshaft bearings that comply with API-610 spacing guidelines and can be greased-for life, product lubricated, or externally flushed.

Common options include larger than standard discharge piping, steel or stainless steel suction strainers, and 316 SS underliners. Along with these, duplex pumping units and accessories such as automatic greasers and control panels with float switch actuators and automatic start/stop sequencing are also available.
