Dosing valves - Import export

The eco-PEN330 precision volume dispenser made by ViscoTec enables many applications in the low to high viscosity dispensing range. The preeflow® eco-PEN is a rotating, absolutely pressure-tight displacement system consisting of a self-sealing rotor and stator. The controlled rotary movement of the rotor generates the flow by displacing the medium in the stator. Pumping without changing the medium is guaranteed. As the material can also be conveyed backwards, preeflow® guarantees a clean, controlled material or medium tear-off without dripping. - True volumetric dosing - Retreat effect - Viscosity-independent dosing - Easy cleaning - dosing independent of inlet pressure - Adjustable dosing flow - Pressure-tight without valve - Dosing pressures from 16 to 20 bar

The ViscoMT-D bin emptying system offers a modern way of emptying small containers and bins cleanly. The use of our dispenser series for the removal of the medium offers the following advantages: - container sizes from approx. 100 ml to 5 l - viscosities of approx. 80,000 - 1,000,000 mPas - very low shear stress of the medium - very low pressure load of the medium (max. 18 bar) - Removal of filler-loaded material - no backflow within the withdrawal pump - electrical control of the pump with pressure control - direct dosing from the container possible - valve-free pump system - no material pressure reducer necessary due to electronic pressure adjustment - very good residual emptying (less than 1% residue) - electronic "empty" and "almost empty" message Application: Removal of materials directly from the delivery container, e.g. silicones, adhesives, resins, fats, colour pastes, metal-filled pastes (Cu and Ni solder pastes, Al and Ag pastes)

After every successful filling of a package, it is a basic condition for precise dosing that the thread is defined and breaks off cleanly. This effect usually occurs with water-like materials - with viscous products, so called semi-solids, but often not: Many products such as creams, gels and ointments pull long threads from the tip of the dispensing needle into the respective packaging. The ViscoTec Pharma Dispensers provide a solution: After a dosing shot of the Pharma Dispenser, the product path through the chambers in the rotor-stator system is blocked, thus preventing dripping of the dosing medium. A valve at the dosing needle or at the pump is not necessary. Thanks to the reversible direction of rotation, retraction can be set after the end of dosing: The material is drawn back into the dosing needle in a defined manner.

Sealing lubrication of sliding surfaces, e.g. ground-in parts such as taper plugs, dosing plungers, valves, beer taps etc. Maintenance lubrication of plastic and rubber parts, as well as stuffing boxes, lip seals and O-rings Rolling and friction bearing lubrication in slow-running areas, toothing or chains on filling and packaging machines, stirring and grinding mechanisms etc. Advantages and benefits Highly effective due to proven lubricant formula Fulfils most demanding hygienic requirements. Reduced maintenance and lubricant costs due to possible long-term lubrication Resistant to hot and cold water, water vapour, wateryalkaline and acidic disinfectants and cleaning agents Neither hard residues result, nor is there a tendency to soften or drip due to pasteurisation or sterilization Odour and taste-free, and does not affect the properties of beer foam Toxicologically harmless as defined in German LFGB

Grease lubrication of plain and roller bearings with low bearing play as well as bearings with low coasting moments Lubrication for fast-running roller bearings Sealing lubrication of mating surfaces, for example ground-in parts such as taper plugs, dosing plungers and valves Maintenance lubrication of plastic and rubber parts with embrittlement protection and good frictional characteristics, particularly on metal surfaces Advantages and benefits Temperature range from -60°C to 120°C Resistant to all alkali and acid cleaning agents and disinfectants Good wear protection through PTFE NSF H2 registration
