Which configurations are listed as types of centrifugal pumps?

• A. End Suction Configuration
• B. Horizontal Inline Configuration
• C. Overhung Impeller; Impeller Between Bearings; Turbine or Vertical Impeller
• D. Self-Priming Configuration

Answer: (C)

Understanding centrifugal pump configurations revolves around how the impeller is mounted and the pump’s orientation. The set that includes overhung impeller, impeller between bearings, and turbine or vertical impeller covers the main mounting/orientation families used in centrifugal pumps: an overhung impeller is mounted on one end of the shaft with support on the other, a between-bearings arrangement uses supports on both ends for greater rigidity, and a turbine or vertical impeller refers to vertical pumps with a vertical shaft. These describe the core ways the impeller is supported and arranged inside the pump. End suction and horizontal inline describe where the connections are rather than how the impeller is supported, and self-priming refers to a capability rather than a fundamental configuration. So the three-mounting/orientation options form the correct group.
