In summary, gear pumps are uniquely suited for handling high-viscosity liquids due to their positive displacement principle, which guarantees a steady, pulseless flow independent of pressure changes. Their advantages in self-priming, robustness, and ability to handle thick fluids efficiently make them an indispensable solution across industries from chemical processing to food and beverage. A successful application hinges on a meticulous selection process that accounts for fluid properties, material compatibility, and operational requirements, ensuring reliable performance and long service life in challenging pumping tasks.
