In a close-coupled pump design, where is the impeller mounted?

In a close-coupled pump design, the impeller is mounted directly on the motor shaft. This design minimizes the space and components required for operation, as it eliminates the need for a separate pump shaft or coupling. By attaching the impeller directly to the motor shaft, the pump achieves higher efficiency and reduces the risk of misalignment and vibration associated with additional coupling components. This configuration also simplifies the assembly and maintenance of the pump, making it an attractive design choice for various applications.
