The ITT Goulds brand is renowned for manufacturing the highest quality pumping equipment utilizing the best engineering practices available worldwide. The Goulds GIS series back pull out, foot mounted centrifugal is no exception. The single stage end suction pump has been designed with the latest CAD (Computer Aided Design) and CFD (Computational Flow Design) aids and is in accordance with the international standard ISO2858. This highly efficient and flexible design makes the Goulds GIS pump ideal for a wide range of pumping applications, from Water Supply and Irrigation to Mining and Building Services.

Design Versions

The Goulds GIS series is manufactured in two designs; Frame Mount suitable for long coupled or belt driven motors and Stub Shaft suitable for direct attachment to 2 or 4 pole IEC frame motors. The standard horizontal configuration units have a vertical centreline 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’s bearing housing.

Pumped Liquid

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).

Construction materials

The Goulds GIS range comes standard with Cast Iron (GG25) casing wet end, Zinc Free bronze impeller and wear rings and a 420 Stainless Steel shaft. In order to suit a wider range of applications the GIS series of pumps is also available in the following materials:

• Ductile Iron
• 316 Stainless Steel
• Duplex Stainless Steel (1.4460)
• CD4MCu

Shaft

Enlarged shaft to minimize deflection, with tapered shaft keyed design ensuring positive locking when in operation and ease of impeller removal whilst servicing. Optional shaft materials are available on request.

Shaft Sealing

A wide range of sealing solutions are available for the Goulds GIS Series, the standard supply consists of a carbon rotating face and ceramic stationary face with nitrile elastomers. For alternative sealing requirements for hot or abrasive applications contact your authorized ITT Goulds distributor.

Features incorporated into the design of the Goulds GIS bearing housing makes it robust, reliable and easy to service. Standard features include a removable bearing cap on the non-drive end and lip seals fitted to both drive and non-drive ends in order to minimize the ingress of foreign liquids and materials. Bearings are heavy duty NSK or approved equivalent bearings with pre-packed grease. Alternative bearing manufacturers and lubrication methods are available on request. The Stub Shaft version has a heavyduty cast iron motor adaptor and robust drive shaft clamp for positive motor alignment and stability.
