WITTE offers pumps for applications in borderline areas. We develop durable, standardised or customised solutions of the highest precision. For more than 35 years WITTE has specialised in the development of gear pumps for industrial applications. It is our endeavour to always guarantee the customer the highest level of process reliability and to match the pumps exactly to the application and the process. In this way we guarantee the best efficiency and durability of our pumps. Reduced maintenance costs and intervals due to matched material pairings guarantee a fast payback the investment costs. We have been working successfully for many years with well-known companies and innovation drivers from the industry and are constantly developing new solutions. Should we not have the right solution at hand, we develop together with our customers the suitable product. We accompany our customers during the entire project from the prototype to the final product. Experts from sales, project management and design form the project and development team and keep us informed of the project status at all times. More than 35 years of experience and the knowledge of our competence team flow into each of our pumps.

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.
