What is the configuration of a centrifugal pump in terms of stages?

The configuration of a centrifugal pump can indeed be classified into single stage or multi stage setups. In a single-stage centrifugal pump, there is one impeller and one stage of pumping action, which makes it suitable for applications that require lower pressure increases and flow rates. On the other hand, multi-stage centrifugal pumps have multiple impellers arranged in series, which allow them to generate higher pressures and are often used in applications such as water supply, boiler feed, and oil transportation.

The ability for a centrifugal pump to be either single-stage or multi-stage broadens its applicability across various industries and performance requirements. This versatility is essential for engineers and technicians when selecting the appropriate pump for specific operational needs. Options such as only being double stage or triple stage would limit the understanding of centrifugal pump configurations, as pumps can operate efficiently in both configurations with a variety of stages based on requirements.
