The Knipex metal rotor pump is a positive displacement, volumetric pump. The metal rotor rotates within the circular channel of the pump chamber, altering the working volume through relative motion between the rotor and the pump body, thereby increasing the energy of the conveyed medium. On the side of the rotor in contact with the conveyed medium within the pump, energy is directly applied to the medium in the form of static pressure. With the squeezing action of the rotating rotor, the medium is expelled while space is left on the other side to form a low-pressure area, allowing for continuous suction. The gaps between the rotors and the pump body are between 5 to 30 threads (depending on the viscosity and characteristics of the conveyed material), with the surface tension of the liquid compensating for the leakage. The mechanical seal employs materials and structures resistant to dry wear, offering no-load operation capabilities.
