覆されてなることを特徴とするベーンポンプ。 A rotor fixed to one end of a cantilever rotating shaft having a horizontal axis is rotatably disposed within a liner fitted to the inner surface of a casing, and the rotor is provided with vane grooves orthogonal to each other at the axis. A vane is attached to each of these grooves so as to be slidable along the rotor radial direction, and the flow path inside the liner has the same cross-sectional area from the fluid intake port on the outer periphery of the rotor to the fluid discharge port. The vane pump is characterized in that the liner is made of stainless steel, and the vane has a main body made of stainless steel, at least a portion of which is in contact with the liner is coated with a stellite layer.
