What is a common preventive measure taken for pumps in mechanical maintenance?

Regular inspection and replacement of seals is a key preventive measure for maintaining pumps because seals play a crucial role in preventing leaks of the fluid being pumped. When seals are worn or damaged, they can allow fluid to escape, leading to reduced efficiency, potential damage to the pump components, and environmental hazards. Regularly checking seals ensures that any deterioration is caught early, thus preventing costly repairs or replacement of the entire pump.

While inspecting and cleaning filters, applying grease to moving parts, and monitoring speed and performance are also important maintenance practices, they do not specifically target the integrity of the pump's sealing system, which is critical for operational efficiency and reliability. Therefore, focusing on seals as a preventive measure directly impacts the safe and efficient operation of the pump system.
