Centrifugal pumps are a fundamental component of modern fluid transfer systems, widely deployed across industrial, municipal, and commercial sectors. These dynamic pumps are designed to convert mechanical rotational energy—typically supplied via an electric motor or engine—into hydrodynamic energy in the form of fluid velocity and pressure. This energy conversion is accomplished through the use of a rotating impeller, which imparts kinetic energy to the fluid by centrifugal force, subsequently transformed into pressure energy within the volute or diffuser casing.
The operating principle of centrifugal pumps is governed by Bernoulli’s equation and the law of conservation of angular momentum, making them ideal for continuous-duty applications where steady, non-pulsating flow is critical.
Key performance attributes include:
High reliability and mechanical simplicity, reducing wear-prone components and maintenance requirements.
Wide operational envelope, supporting a broad range of flow rates, pressure heads, and fluid viscosities.
Compatibility with clear liquids, corrosive solutions, low-viscosity hydrocarbons, and light slurries, depending on impeller and seal configuration.
