The ViscoTec preeflow® eco-PEN700 is a new volumetric metering system.

Here, the proven technology of the eccentric screw pump is incorporated in a miniaturized design. New manufacturing processes and materials have made it possible to transfer the complex geometries of the screw conveyor and the stator into this small design. Now, for the first time, media in very small quantities can be conveyed fully volumetrically both forwards and backwards. This also ensures a clean break-off of the medium.

How it works

Preeflow dispensers are rotating positive displacement pumps. The conveying elements consist of a rotating part, the "rotor", and a stationary part, the "stator". The rotor, which is a type of round thread, rotates in the stator, which has one more thread and twice the pitch length of the rotor. This leaves conveying spaces between the stator and the rotor, which rotates in it and also moves radially, and moves forward continuously. The flex shaft driving the rotor compensates for the eccentric movement of the rotor and is completely maintenance-free.
