The invention discloses a vane type pump, which comprises a shell (1), the housing (1) inside the cavity separated with water (2) and the water pressure chamber (3), the absorbing cavity (2) is arranged on the transmission shaft mounting hole (4), the absorbing cavity (2) through the transmission shaft mounting hole (4) is connected with the drive shaft; the water chamber (2) is arranged in at least one spoiler bars (5). So, in the working process of vane pump, the water is located in the cavity of the water through the collision and contact with the spoiler bars, can change the direction of movement of water, waterproof seal so that the water is more concentrated in the water between the cavity and the drive shaft, which can better heat sealing, thereby prolonging waterproof seal service life, reduce maintenance cost of water pump.
