Why is maintenance often an issue for gear pumps?

Gear pumps can encounter maintenance issues primarily due to their exposure to corrosive chemicals, which can negatively impact the gears' integrity over time. When these chemicals come into contact with the gears, they can lead to corrosion, wear, and tear, ultimately resulting in decreased performance and lifespan of the pump. This necessitates regular maintenance checks to ensure that the gear materials are stable and the pump operates effectively.

While lubrication, repair difficulty, and clogging can also pose challenges in other types of pumps, in the context of gear pumps, the primary concern relates to the effects of corrosive substances on the gears themselves. This highlights the importance of understanding the specific conditions under which gear pumps operate and the types of fluids they manage. Ensuring they are suited for the chemicals being pumped is vital to maintaining their functionality over time.
