2-Component Dosing Systems

2K Dispenser ViscoDuo – V 4/4

The 2-component ViscoDuo-V 4/4 dispenser is a valveless, static mixing head with dispensers located directly in front of the mixer.

The mixing head functions valve-free. The components to be mixed are dosed by volume only and with no dead space into the static mixing tube via the dispensers.

 Main features of VsicoDuo-V4/4:

• Processing of viscosity materials with no filler or very high filler content
• Only low supply pressure required for medium feed
• Adjustment of the desired mixing ratio by adjusting the speed ration of both dispensers
• Integrated sensors in each component (no dead space) for online process monitoring
• Reverse-flow possible (no dripping or stringing of product)
• Connection between dispensed quantity and speed is absolutely linear
• Constant dosing volume, even with density or viscosity changes due to temperature fluctuations or batch change

eco-DUO450/600

Preeflow® eco-DUO 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 movement.

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.

APPLICATION

On-the-dot dosage with maximum volumetric precision – dot-and-bead application with application speeds adaptable to track speeds – joint sealing technology.
