Specific speed is an index used to predict desired pump or turbine performance. i.e. it predicts the general shape of a pump's impeller. It is this impeller's "shape" that predicts its flow and head characteristics so that the designer can then select a pump or turbine most appropriate for a particular application.
Pump curves are quite useful in the pump selection, testing, operation and maintenance. Pump performance curve is a graph of differential head against the operating flow rate. They specify performance and efficiency characteristics. Performance tests are done on the pumps to verify the claims made by the pump maker.
The first turbine they built in 1856 was installed at Holmescales Farm at Old Hutton and powered farm machinery there for more than a century. This, the "Williamson Bros Vortex Turbine No. 1", survives and is in the collection of Lakeland Arts ; it was part of the Museum of Lakeland Life & Industry in Kendal, as of January 2021 [update] closed ...
Goulds Water Technology is a brand of Xylem Inc. providing pumps for residential, commercial and agricultural applications and Goulds Pumps remains a part of ITT Corporation providing pump products for the industrial market. Xylem comprises three business units – Water Solutions, Analytics, and Applied Water Systems.
Unlike a compressor or fan, surge or stall does not occur in a turbine. This is because the gas flows through the turbine in its natural direction, from high to low pressure. As a result, there is no surge line marked on a turbine map. Working lines are difficult to see on a conventional turbine map because the speed lines bunch up.
Warman centrifugal pump in a coal preparation plant application A pair of centrifugal pumps for circulating hot water within a hydronic heating system. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine ...
Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface water (e.g., irrigation, drainage of lands, ...), while high-lift pumps allow deep water pumping (e.g., potable water pumping ...
