ViscoTec Pumpen- u. Dosiertechnik GmbH

Perfectly dosed!

Emptying, Dosing and Filling Systems of low to high viscosity fluids

ViscoTec produces dosing systems and dosing components – for the integration into complex multi-row filling production lines or into semiautomatic filling stations. From process reliable, high precise filling under highest hygienic requirements (EHEDG, FDA) for the food industry to liquid preparation and barrel emptying of semi-solid pastes: ViscoTec products cover a wide range of applications. They are particularly suitable for highly viscous, shear sensitive or even solid containing material (for example filling of sauces with flavorings, filling of tomatoes cut in pieces, filling of honey, chocolate, marinades, yoghurt, caramel, jam, marmalade, tomato paste, fruit mass and many more). The technology focus is dosing, application, filling and product handling like degassing or emptying of various products. The company core competence is the processing of highly viscous, solid containing, abrasive or shear-sensitive liquids or pastes. All fluids showing a viscosity of up to 7.000.000 mPas can be conveyed and dosed almost pulsation-free and with extremely low shear force. ViscoTec offers technically advanced solutions for all components of a complete system: from emptying (whether from a bin, bucket, barrel, hobbock or cartridge) to preparing and to dosing.

The endless piston principle:
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.

Advantages of the endless piston principle:
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.

Your advantages:
Customers of ViscoTec all benefit from a technology which, along with other technical features, offers reliable, accurate and fast dosing that helps them to increase the quality of their own products. For each application, the customer receives comprehensive advice from ViscoTec specialists and experts in order to achieve the best results. Thanks to the 24/7 support available from ViscoTec, optimum service around the clock is ensured. ViscoTec offers its customers a precise, reliable, fast and sophisticated technology. The products are tailored to perfectly match the respective application. The extraordinary quality and work has been rewarded in 2014 with the „Bayerns Best 50“ award and in 2015 with the „Best of Industriepreis“ award.
