Precision volume dosing unit eco-SPRAY

The innovative precision-volume-dispenser eco-PEN700 made by ViscoTec offers a wide range of applications for low to medium-viscosity dispensing. preeflow® eco-PEN is a rotating and perfectly pressure-tight displacement system. Self-sealing rotor/stator design. Conveyance action by medium displacement in the stator through controlled rotor rotation. Safe conveyance without any modification of the medium. With its suck back option, preeflow® ensures clean and controlled material or medium cut-off while preventing post-dripping effects.

The compact 3VPHD8 Pharma Dispenser enables precise and reliable dosing of a wide variety of materials. Thanks to the special rotor-stator-geometry, no valve is required to prevent the medium from flowing out independently. Alternating opening chambers ensures gentle product transport and pulsation-free output. The VPHD series was specially developed for applications in the pharmaceutical, biotechnology, medical and food industries. Your advantages: - Interior with optimised dead space - Design according to EHEDG guidelines - FDA-compliant design/development - hygienic and pharmaceutical design - Works certificate 3.1 (DIN EN 10204) - all surfaces for pharmaceutical applications Ra ≤ 0.8 μm - retraction option (no dripping or thread pulling) - absolutely linear relationship between rotor speed and spread rate - long service life due to media-specific component selection

In order to avoid chemical reactions such as curing or crystallization during the dosing process, any contact with metal in the area in contact with the material in the dispenser was avoided. The materials used have been carefully selected: On the one hand with regard to chemical resistance to adhesives and other fluids and on the other hand with regard to highest resistance to physical wear by abrasive media. Highly reactive materials such as sulfuric acid, anaerobic UV curing acrylates and electrolytes require special treatment. They can be dosed with highest accuracy and best repeatability. The new metal-free dispenser can be easily installed on existing ViscoTec drive technologies and offers the same advantages as other proven dispensers from the portfolio of the dosing technology specialist. The metal-free dispenser is available in many sizes.

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
