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.

Pumped Liquid

Our end suction pump is designed for non-combustible, low viscosity liquids, free of solids, abrasive materials and fibres. Various liquid chemical compositions are capable of being pumped through the use of a variety of construction materials and seal options (Refer to materials listed below).

Operating Conditions

Flowrate: Max. 2100 m3/hr

Pump Head: Max. 160 meters

Liquid Temp: -15 ℃ to +120 ℃ (Standard Version)

Max Working Pressure: PN16 and PN25 (optional)

Features

• Designed in accordance with ISO 2858 standard

• Variety of conﬁguration options: compact, block and frame-mounted designs

• Extensive material options for casing and impeller, from bronze to super-duplex

• Easy maintenance and spare parts management (modular construction, back pull-out design)

• Improved reliability and extended pump life (robust construction, reduced stress on bearings)

• Standard wear rings which reduce wear and lower maintenance costs

• Reduced life cycle cost and optimized total ownership cost
