Vane pumps are mechanical devices used to move fluids in various applications. Instead of gears, vane pumps utilize small vanes or blades that slide in and out of slots within a rotating rotor. As the rotor spins, these vanes create chambers that expand and contract, drawing in and expelling the fluid. Vane pumps are known for their smooth operation and ability to handle thin liquids effectively. They are often chosen for their reliability and quiet performance in a range of industrial settings.
