Performance Characteristics of Centrifugal Pumps

Performance Characteristics of Centrifugal Pumps. Although the theory of centrifugal pumps gives many qualitative results, the most important indicator of a pump’s performance lies in extensive hydraulic testing.. In industry, characteristics of all pumps are usually read from its Q-H curve or performance curve (flow rate – height).As can be seen, the performance charts use a discharge

Centrifugal pump Wikipedia

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 or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid enters the pump
