TAIWAN  CML VCM-SF-12A-4CG-20  Variable Volume Vane pump

When the rotor of the vane pump rotates, the blade is attached to the inner surface of the stator by the centrifugal force and the pressure oil.The working volume of the two blades and the inner surface of the rotor and the stator is made from small to large oil and then to small oil, and when the blade is rotated for a week, the oil and oil will be completed once.
