A worn mechanical seal on the pump shaft can lead to various negative effects. Firstly, it can cause leakage of the fluid being pumped, resulting in decreased efficiency and potential damage to surrounding equipment. Secondly, it can lead to increased friction and heat generation, which can accelerate wear and tear on the pump shaft and other components. Lastly, a worn seal can allow contaminants to enter the pump, potentially causing further damage and reducing the overall lifespan of the pump.
