Vane pumps are positive displacement pumps that generate suction and discharge pressure using a rotating impeller with vanes or blades that slide into and out of a cylindrical cavity. To ensure a constant flow of hydraulic fluid, they are frequently used in hydraulic systems. They are more common in low-pressure applications and have a more straightforward design. Industrial uses for Vane Pumps include hydraulic power units, presses, injection molding machines, and machine tools. The advantages of these pumps include their high efficacy, small size, and low noise levels. They can handle a wide range of fluid viscosities and are also fairly simple to maintain and repair.
