Vane pumps are a type of positive displacement pump that use rotating vanes to move fluid. They consist of a rotor with slots that hold the vanes, which extend outward as the rotor turns. This action creates chambers that trap and transport the fluid, making vane pumps efficient for various applications, including hydraulic systems and fuel delivery. These pumps can handle a wide range of viscosities and are known for their smooth and consistent flow. Vane pumps are commonly used in industries such as automotive, aerospace, and manufacturing, where reliable fluid transfer is essential for operational efficiency.
