Single stage end suction pump. Goulds Water Technology is renowned for manufacturing the highest quality pumping equipment utilizing the best engineering practices available worldwide. The GISO / GIS series back pull out, foot mounted centrifugal is no exception. The single stage end suction pump has been designed with latest CAD (Computer Aided Design) and CFD (Computational Fluid Dynamics) and is accordance with the international standard ISO2858. This highly efficient and flexible design makes the GISO / GIS series pump ideal for wide range of pumping applications, from water supply and irrigation to mining and building services.

Design Versions

• The pump comes in two designs: GISO frame mount series is suitable for belt motors and GIS close coupled series is suitable for direct attachment to 2 or 4 pole IEC frame motors. The standard horizontal configuration units have a vertical centerline discharge; however these models can also be mounted in a variety of different positions including horizontal discharge, with or without vertical mounting of the pump bearing housing.
