A major challenge in dosing technology is still the gentle dosing of solids laden liquids, without damaging the solids. Viscotec provides pharmaceuticals for this Dispenser Hygienic design ensures a reliable dosing process.

For longer standstill of solids laden liquids there is a risk that the solids settle. The material sediments. If this happens, the dosing device clogs and must be completely disassembled and cleaned. The entire dosing process is interrupted.

In the Pharma Dispensers, which comply with all relevant hygiene guidelines, an additional circulation nozzle is integrated. The proven eccentric screw technology of the manufacturer enables a circulation of the material to be dispensed down to the pump housing. So no rinsing steps must be performed before dosing. In addition, the uniform volume flow and the comparatively low pressures prevent sedimentation of the solids. Due to the low shear, the solids can be dosed undamaged.

Other technologies, such as hose and piston pumps, crush the solids or damage them by excessive pressures. In addition, in these pumps, the material can be circulated only in the container and in the manifold, which often leads to clogging of the metering pump. This must then be cleaned in several rinsing steps and it takes some time until the production runs smoothly again.

  • Viscotec carried out customer-specific tests for microdosing in the Preeflow technical center. The fully automatic production of fiber optic cables was checked using a 2K dispenser. The customer requested the repeated application of 5 µl of a two-component material in a volumetric mixing ratio of 8,5: 1. The epoxy adhesive EPO-TEK353ND was used.
  • With the new office in San Diego, Viscotec is now also present in Southern California. The solution provider for sophisticated dosing processes also celebrated its tenth anniversary in the United States at the end of 2019. Viscotec America offers high-precision dosing of 1- or 2-component materials based on the progressing cavity pump technology.
  • Viscotec has further developed its proven stainless steel rotor for the reliable dosing of abrasive fluids such as thermally conductive 1K and 2K gap fillers, 1K thermal pastes or highly filled 2K adhesives. The new version in the form of a ceramic rotor enables significantly longer service lives for this core component of the dosing system.
  • Productronica Hall A4, Booth 405 Viscotec presents optimized dispenser series for even smaller dosing quantities in the 1K and 2K range. The ceramic rotor especially for highly abrasive materials and an optimized version of a mixing block for materials that are difficult to mix will also be on display.
  • On October 01, 2019 Viscotec opened a new branch in Mérignac, Bordeaux. The subsidiary in France is the fifth branch worldwide. It is planned as a sales, service and support organization that will sell and support both Viscotec and Preeflow products.
  • Fachpack Hall 3A, Booth 127 A major challenge in dosing technology is still the gentle dosing of solids-laden liquids without damaging the solids. Viscotec provides pharmaceutical dispensers with a hygienic design to ensure a reliable dosing process.
  • Viscotec now also offers its VHD Hygienic Dispenser with a hard chrome-plated rotor. The combination of optimized material and established technology will open up an even broader spectrum for users in the future. The manufacturer is thus responding to the demands in the cosmetics industry for more flexible and less wear-filling processes.
  • Cover story ready-made sauces are practical. But also a challenge for the bottlers and their machines in food technology. In addition to filling, the mixture of many ingredients also plays a central role in the manufacturing process. The possibilities and variations are almost unlimited. In a Viscotec project, various ingredients with different viscosities or lumpy materials are dosed, mixed and filled.
  • The new 4VPHD6 pharmaceutical dispenser from Viscotec expands the VPHD series in GMP design. Developed for hygiene applications in the pharmaceutical industry, biotechnology or medical technology, the Hygienic Dispenser series convinces in numerous applications. Because the market has asked for even smaller dosing quantities, the manufacturer has expanded the series with a dispenser for filling small quantities of 0,1 ml or for continuously dosing 0,2 ml / min.
