Why is maintenance often an issue for gear pumps?

The issue of maintenance for gear pumps often stems from the fact that corrosive chemicals can come into contact with the gears. Gear pumps are designed to handle various fluids, and when these fluids include harsh chemicals, the materials that compose the gears can degrade over time. This contact with corrosive substances can lead to faster wear and tear, necessitating more frequent maintenance to ensure the pump remains effective and does not fail prematurely.

The degradation of gears due to chemical exposure can also lead to operational issues, such as reduced efficiency or leaks, further complicating maintenance efforts. Proper selection of materials that can resist the specific chemicals being pumped, as well as regular inspections and maintenance, is crucial for the longevity and functionality of gear pumps in environments where corrosive materials are present.
