Which of the following is a characteristic of centrifugal pumps?

Centrifugal pumps are known for their efficiency and effectiveness in providing consistent flow rates, making them a preferred option in various applications, including water supply systems. Among the characteristics listed, self-priming capabilities stand out as a key trait of centrifugal pumps, particularly when designed to include this feature. This means they can draw liquid into the pump without the need for external priming, facilitating ease of operation in many scenarios.

Additionally, centrifugal pumps are typically designed to handle various pressures effectively, with many models capable of operating efficiently at higher pressure outputs, which dispels the incorrect notion associated with low pressure output. They also excel in systems where space may be limited, showcasing effectiveness even in cases where clearance issues are present. While high maintenance requirements can be relevant to some types of pumps, centrifugal pumps are generally favored for their relative low maintenance needs when operated under optimal conditions.

Understanding these characteristics can help in selecting the right pump type for specific applications, ensuring reliability and efficiency in water supply systems.
