ViscoTec produces dosing systems and dosing components for semi or fully automatic production lines and assembly processes. From precise micro dispensing, in the microliter range, to speed-proportional bead dosing, from potting applications, two-component mixing applications or from high precise filling under highest hygienic requirements for the pharma industry to liquid preparation and barrel emptying of semi-solid pastes: ViscoTec products cover a wide range of applications.
All dosing and filling units of the company are based on the endless piston principle which belongs to the group of rotary positive displacement pumps. The functionality is comparable to an endless piston that feeds the product from the suction side to the pressure side and builds up a pressure difference in doing so. The core element of each application is a volumetric dispensing pump. The interaction of an eccentrically moving rotor into a corresponding stator results into a similar flow and dosing characteristics of an endless moving piston.
The rotor / stator geometry ensures that a constant volume is always flowing proportionally to the rotation angle per revolution. So the volume is exactly defined by the angle of rotation of the rotor. The flow direction is reversible by changing the direction of rotation, the pump curve is pressure stable and absolutely linear. This enables you to get a clear overview about the ratio between revolution, time and volume rate. This results in a guaranteed dosing accuracy of 1% at the pump outlet (depending on the fluid) which often is much lower in practice. One further benefit is the emerging dosing chamber. Its volume is absolutely constant during the motion, which gives the possibility to dispense solid-containing fluids and even extremely shear-sensitive chunky products. And in over 95% of all applications there is no need for any filling and dosage valves at all, since a short reverse motion at the end of the dosing process break the thread off and therefore prevents dripping.

Valveless, static mixing head with two dispensers. Especially developed for simplified cleaning (Easy Clean) and maintenance. In the mixing head no valves are required. The components to be mixed are dosed by volume only and with no dead space into the static mixer.

• static mixing of two components of same or different viscosities
• potting dot or bead applications possible
• suitable for 2-component adhesive systems based on: epoxy resin (EP), polyurethane (PU), silicone (Si), acrylates
• application of high-content gap fillers and thermally conductive pastes
• mixing of two colours
