Girdlestone Industrial – SSM/SSD Pump
Girdlestone manufactured this range of centrifugal pumps to cover the low flow end of the pumping spectrum, with robust reliability needed for the more difficult pumping needs of industry – particularly with the chemical, pharmaceutical and marine markets in mind.
Amarinth’s equivalent to the Gridlestone SSM and SSD ranges is fully interchangeable both hydraulically and dimensionally requiring no pipework modifications and provides many more years of reliable service from this proven workhorse.
The units are available in both close-coupled and direct coupled formation, with a variety of mechanical sealing options.
Materials of construction include stainless steel, bronze, cast iron, and a selection of sophisticated alloys, for highly corrosive or erosive applications.
Construction is kept simple and incorporates the back pull out principal now established as the ‘norm’ for pumps designed with the maintenance engineer in mind.
Using modern computer aided design software the pumps are designed as a light to medium duty, minimal wear, long life pump. This original Girdlestone design has been in use for many decades and is a well proven, reliable workhorse. The Amarinth S Series replacement is aimed at customers who want the same reliability and minimum disruption when a new replacement is required for their existing Girdlestone pump.
To complete the package a full range of standard material options including cast iron, stainless steel and gunmetal are available to match your process fluid. Standard documentation packs including data sheets, material certification, installation and operating manuals are available to suit the application. Performance testing to BS EN 25199 / ISO 5199 and various NDE (non destructive examination) and NDT (non destructive testing) options are offered to ensure full compliance to our customer's specifications. Alternative bespoke packages can be tailored to fit your exact requirements.
