Operating Principle of a Rotary Piston Pump

Nakakin rotary piston pumps operate due to the positive displacement device principle. The two rotors on parallel axes run by a synchronized gear and rotate in the opposite direction to each other. They touch neither each other nor the casing. The sealing of the chambers that convey the product is only operated by the clearance between casing and rotor that should be as small as possible. The conveyance occurs gently and with low-pulsation. Even particles can be conveyed by a rotary piston pump.
