End Suction Fire Pump Driven by Diesel Engine

Introduction of End Suction Pump

The GISO / GIS series end suction pump is a flexible and highly efficient foot-mounted single-stage end-suction pump with back pull-out design. This pump has been designed with latest CAD (Computer Aided Design) and CFD (Computational Fluid Dynamics), and is manufactured with the best engineering practices worldwide. This highly efficient and flexible design makes the GISO / GIS series end suction pump ideal for wide range of pumping applications, from water supply and irrigation to mining and building services. 

Design Versions

The GISO / GIS end suction pump comes in two designs: “GISO” long coupled (frame mount) series is suitable for belt driven motors and “GIS” close coupled (stub shaft) 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.
