    The design also conveying and metering of highly abrasive media. ViscoTec dispensers are rotating displacement pumps. The conveying elements comprise a rotating part, the "rotor", and a stationary part, the "stator". The rotor, which is in the form of a type of round thread, rotates inside the stator, which has one more thread turn and twice the pitch length of the rotor.
