Water engineering research continues to be paramount in areas such as coastal research, environmental modelling, sediment transportation and irrigation studies. For over 50 years, Armfield have been designing and supplying open channel facilities (also referred to as flumes) to hydraulic laboratories throughout the world. Our brochure presents the standard range of channels/flumes available from Armfield More
The Armfield Multi-Pump Test rig can accommodate both rotodynamic and positive displacement pumps, and is supplied with the most common example of each type as standard (ie a centrifugal pump and a gear pump). A range of other pump types are available as accessories, (including axial, turbine, flexible impeller, diaphragm and plunger, plus a second More
