Nous travaillons avec succès depuis de nombreuses années avec des entreprises renommées et des moteurs d`innovation de l`industrie et nous développons constamment de nouvelles solutions. Si nous n`avons pas la bonne solution sous la main, nous développons avec nos clients le produit approprié. Nous accompagnons nos clients tout au long du projet, du prototype au produit final. Des experts en vente, en gestion de projet et en conception forment l`équipe de projet et de développement et nous tiennent informés à tout moment de l`état d`avancement du projet. Plus de 35 ans d`expérience et les connaissances de notre équipe de compétence se retrouvent dans chacune de nos pompes.

La pompe vide-fût de la maison JESSBERGER convient au pompage de fluides peu visqueux tels que les acides, les bases et les produits de nettoyage (avec mécanisme de pompage en polypropylène), les produits chimiques très agressifs (avec mécanisme de pompage en PVDF), les produits pétroliers jusqu'à 1.000 mPas (avec mécanisme de pompage en aluminium) ou les fluides inflammables ainsi que les produits alimentaires (avec mécanisme de pompage en acier inoxydable 1.4571).

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.

Customers of ViscoTec come from many different
industries like automotive, aerospace, electronic engineering, general
industry, plastics, new energies, food, biochemistry, pharmaceutics, cosmetics
or the medical sector. They 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. It belongs to
the premium market sector. 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.

ViscoTec products are mostly used with adhesives, paints,
soldering pastes, sealants, in medical technology, cosmetics (mascara, vaseline,
perfume and others) or in the food sector (e. g. sauce filling with aroma
concentrates). The technology focus lies on dosing (1K/2K), applying, filling
and material treatment like degassing or barrel emptying of several different
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, available as standard products or as part of a
modular design. In addition the company creates solutions for the most
challenging, customer-specific applications and is the single point of contact
to deliver all components for a complete system: from emptying to preparing and
to dosing. This guarantees a successful interaction of all components. To control
the special requirements of each application, ViscoTec performs, for example,
excellent tests in its own laboratory, in close cooperation with the customers.

Battery pumps are portable, battery-operated pumps that can be used in a variety of applications. They are ideal for transferring liquids such as water, chemicals or fuels, especially in places without a power supply. Thanks to their compact design and easy handling, battery pumps are mobile, flexible and practical for use in agriculture, horticulture, on construction sites or in emergency situations. Important features include their efficiency, easy maintenance, robust materials and long battery life. Battery pumps offer a reliable solution for fast and uncomplicated fluid transport.
