How does a circumferential piston pump work?

A pair of winged rotors or pistons rotate in the pump casing around the circumference of the channel. This continuously generates a partial vacuum at the suction port as the rotors unmesh, causing fluid to enter the pump. The movement of the rotors transports the fluid around the channel. The re-meshing of the rotors generates pressure, displacing the fluid at the discharge port. The direction of flow is reversible.
