Liquids dosing dispenser 3RD4-EC

for high-viscosity mediafor paintresin

characterize dosing systems with a constant volumetric operating principle for an uninterrupted and highly precise dosing process by using of the endless piston technology. The dispensers guarantee a precise, consistent and reliable dosing performance for a wide range of liquids and compliance with the specified dosing precision even with varying media densities and viscosities. Special rotor-stator geometries… allow flexible control of the amount of the liquid conveyed and the direction of the medium flow. Alternately opening chambers provide for a gentle transport of the medium inside the dispenser and a pulsation-free output. Each individual dispenser chamber conveys an exactly defined volume of medium and works simultaneously as sealing line in the way of the pump inlet and outlet side. ViscoTec RD-EC Dispenser cross section Valveless dosing technology The valveless system design is based on a circumferential sealing line in order to prevent leakage of the medium at the dispenser outlet side. In addition, the ViscoTec RD-dispensers provide a programmable suck-back option at the end of each dosing step. System integration/precision Dosing quantities in the range from a few μl up to larger ml volumes can be dosed with maximum precision as a dot, bead line application or within potting processes. The dispensers can be integrated into a wide range of axis and robot systems due to their compact and weight-reduced structure. Along with the combined ViscoPro drive and control systems the dispensers can be integrated as overall dosing systems into production lines.
