This site contains general information on pump fundamentals including the design, application, manufacture, assembly, testing, installation, operation, maintenance, servicing, trouble-shooting, hydraulic re-rate, and upgrade of industrial centrifugal pumps.
To navigate this site
Go to our Glossary for definition of technical terms with links to pages where specific topics on centrifugal pumps are discussed in more details.
Or, go to our main topics grouped into Concepts, Parts and Auxiliaries.
Concepts include basic concepts such as affinity laws, cavitation, critical speed, efficiency, head, horsepower, hydraulic thrust, leakage, minimum flow, NPSH, recirculation, resonance, pump specific speed, temperature, torque, velocity, vibration, viscosity, etc.
Parts include components such as barrel, baseplate, bearing, bearing housing, bushing, casing, coupling, cover, flange, gasket, gland, impeller, key, mechanical seal, motor, nozzle, orifice, packing ring, piping, shaft, sleeve, strainer, volute, wear ring, etc.
Auxiliaries include items that are not integral parts of pumps but are used in pumping system or installation, such as motor, hydraulic power recovery turbine, lubrication system, foundation, sump and sump design, etc.
For list of all pump-related topics go to our Sitemap.
