Girdlestone Industrial - URF/USM Pump
Used for many years on an ever increasing variety of applications, the Girdlestone URF and USM range of pumps, with its unique design, adaptability and outstanding performance, has contributed substantially to the general acceptance of close-coupled motor pumps by industry.
Amarinth’s equivalent to the Gridlestone URF and USM range of pumps 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 and front pull out designs depending upon your needs.
Using modern computer aided design software the pumps are designed as a light to medium duty, minimal wear, long life pump. The original Girdlestone design has been in use for many decades and is a well proven, reliable workhorse. The Amarinth U 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.
