Vane pumps are a type of positive displacement pump that use a series of vanes or blades to move fluid. These vanes are mounted on a rotor and slide in and out of slots as the rotor turns, creating a vacuum that draws fluid into the pump and then pushes it out. Vane pumps are commonly used in hydraulic systems and various industrial applications due to their efficiency and ability to handle different types of fluids. One of the key advantages of vane pumps is their ability to maintain a consistent flow rate, even under varying pressure conditions. They can handle both low and high viscosity fluids, making them versatile for applications in automotive systems, such as power steering, and in oil and gas industries. Their design allows for smooth operation and reduced noise, contributing to their popularity in many settings.
