Dilution of pump fluids can lead to which issue?

Dilution of pump fluids can lead to a loss of lubrication and subsequent wear because the effectiveness of the lubricant is compromised when it becomes diluted with other substances, such as water or contaminants. When the lubrication properties of the fluid are diminished, the film strength decreases, which can result in increased friction between moving parts. This friction can cause excessive wear on components like bearings and gears, leading to premature failure and the need for repairs or replacements. Proper lubrication is essential for minimizing wear and maintaining the efficiency and lifespan of mechanical systems, and diluted fluids fail to provide the necessary protection against wear.

While dilution might impact other aspects, such as filtration requirements or flow rate, the primary and critical concern is the lubrication failure that results from it.
