For double chamber vane pumps, the process of filling the chambers (suction) and emptying is in principle the same as for single chamber vane pumps. In this case, however, the stroke ring (i.e. stator) has a double eccentric internal surface. The rotor can be placed in the axis of the stator because of these surfaces, which differentiates them from single chamber vane pumps.
This set up causes each vane to carry out two strokes per rotation of the shaft. All radial loads on the rotor are now neutralized (two pressure ports on each opposite side). The end result is that two pumps have been built together as one. Due to the twin cam forms of the stator, two displacement processes occur per revolution.
