What is a major cause of wear in pump and motor shaft couplings?

Misalignment between pumps and motor flanges is a significant cause of wear in pump and motor shaft couplings. When the shafts of a pump and motor are not aligned properly, it creates uneven forces as the motor operates. This misalignment can lead to vibrations, increased friction, and ultimately excessive wear on the coupling components. The misalignment can be caused by various factors, including improper installation, foundation settling, or thermal expansion, and it can result in failures that compromise the effectiveness and longevity of the pumping system. It is crucial to maintain proper alignment to ensure efficient operation and reduce wear on the coupling, thus prolonging the life of both the pump and motor systems.
