Spacer Coupling Design for Centrifugal Pumps

What is a spacer coupling design for centrifugal pumps?

The spacer coupling design provides a practical maintenance solution for centrifugal pumps by creating sufficient clearance between the pump and motor. This allows the complete rotating assembly, including the shaft, bearings, mechanical seal, and impeller, to be removed as a single unit while the motor remains in place and the pump stays connected to the piping system. The design simplifies service procedures, improves accessibility to critical components, and helps keep maintenance operations efficient.
