Product description
The dispenser has been developed and tested for precision dosing of materials ranging from
low to high viscosity with extremely high repeat accuracy.
preeflow dispensers are positive 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 knuckle thread, rotates inside the stator, which has one more thread turn and twice
the pitch length of the rotor. As a result, conveying areas are produced between the stator
and the rotor rotating inside the stator. The rotor also moves radially within the stator.
The conveying spaces move forward continuously due to the movement. The flexible shaft
used to drive the rotor compensates for the eccentric movement of the rotor and is completely
maintenance-free.
The sealing effect of the conveying elements of the dispenser is dependent on the viscosity
and pressure.
Since the direction of flow is reversible, the material can be sucked back to allow a clean
thread break.
The dispenser can be dismantled very quickly.
Together with the eco-CONTROL EC200 dosing control unit, the dispenser forms a dosing
system which is typically installed in a dosing station. The dosing control unit controls the
required parameters (e.g. dosing quantity, dosing speed, etc.).

Operation
4.1
Initial commissioning
All activities described below may only be carried out by qualified staff.
When delivered, the stator is not installed so as to avoid bearing damage to the elastomer of
the stator.
Preparation
Undo the cap nut (2).
Pull off the end piece (3).
Plug the star-shaped coupling (5) into the bearing housing (13).
Couple the assembly aid (6) to the bearing housing (13).
