Abstract
Centrifugal pumps are used for transporting liquids by raising a specified volume flow to a specified pressure level. Pump performance at a given rotor speed is described by the rate of flow delivered, the pressure rise achieved, the power absorbed at the coupling, the efficiency and the NPSH. Depending on the application a broad variety of pump types are offered on the market. All of these have at least one impeller and a collector where most of the kinetic energy at the impeller outlet is converted into static pressure. Different forms of impellers, diffusers, volutes and inlet casings are available to build radial, semi-axial or axial, single- or multistage, pumps mounted in horizontal or vertical position - as most suitable for the specific application.
