ViscoTec preeflow® eco-DUO600

The ViscoTec preeflow® eco-DUO600 is a pressure-tight 2C mixing system which consists of one rotor per component in the self-sealing stator. The controlled rotation of the rotors generates the delivery by displacing the medium in the respective stator. Conveying without changing the medium is guaranteed. Since conveying can also take place in reverse, preeflow® guarantees a clean, controlled material or media break-off without dripping.

The ViscoTec preeflow® eco-DUO600 has been developed and tested for precise dispensing of media with low to high viscosity at highest repeatability. Preeflow dispensers are rotating positive displacement pumps. The conveying elements consist of a rotating part, the robot, and a stationary part, the stator. The robot, which is designed as a kind of round thread, moves rotationally in the stator, which has one more thread and twice the pitch length of the robot. This leaves conveying spaces between the stator and the rotor, which rotates in it and also moves radially, moving continuously forward. The flex shaft driving the rotor compensates for the eccentric movement of the rotor and is completely maintenance-free. The sealing effect of the dispenser's conveying elements is viscosity and pressure dependent. Since the conveying direction is reversible, the medium can be retracted for a clean thread break.

The dispenser can be disassembled in a very short time. Together with the eco-CONTROL EC200 DUO dosing control, the dispenser forms a dosing system that is usually mounted in a dosing station. The dosing control regulates the desired parameters (e.g. dosing quantity, dosing speed, etc.).
