What type of maintenance is typically performed on pumps to ensure longevity?

Regular lubrication is essential for the maintenance of pumps to ensure their longevity because it reduces friction and wear on the moving parts. Lubrication helps to prevent overheating, which can lead to premature failure of pump components. Additionally, it aids in the smooth operation of the motor and bearings, thereby enhancing overall efficiency and performance.

While calibrating levels, replacing filters, and testing pressure may also be involved in maintaining pumps and their associated systems, these actions do not directly address the fundamental needs of mechanical components in the pump itself. Regular lubrication specifically targets the moving parts that are most susceptible to wear and tear, making it a crucial aspect of a proactive maintenance schedule.
