What type of hydraulic pump is characterized by the use of rotating vanes?

A vane pump is characterized by its use of rotating vanes to create a pressure differential that moves fluid through the system. In a vane pump, the vanes are mounted on a rotor and can slide in and out of their slots as the rotor turns, allowing them to maintain contact with the inner wall of the pump casing. This action generates a vacuum that draws fluid into the pump and a pressure that displaces the fluid out of the pump, making it an efficient choice for many hydraulic applications.

The advantage of this design is that it can provide a smooth and steady flow of fluid, which is particularly beneficial in applications requiring precise control. Vane pumps are known for their versatility and ability to operate at various speeds and pressures, which adds to their effectiveness in hydraulic systems. This distinguishes them clearly from other types of pumps, such as gear pumps and piston pumps, which have different operational mechanisms and characteristics.
