Two-component-paste-pump-Vi-Pro-Dosimac-2K

The Vi-Pro DOSIMAC 2K is a dosing and metering unit for professional two
component silicone (SI), polyurethane (PU) and polysulphide (PS) adhesives
and sealants.

The base material and hardener flow through separate lines and only meet at the gun outlet just before the replaceable plastic mixer. The use of disposable plastic mixers helps to minimise the generation of costly waste.
The unit separates the functions of drawing material from drums and dosing components into the mixing system, which significantly improves the consistency of the mix. The result is an innovative system that provides tangible benefits for
the user:

ENERGY SAVING
– the automatic stop-start system stops the hydraulic power pack during breaks in the mixture dosing which saves
electricity and minimises oil heating.

REDUCED WASTE COSTS
– elimination of the use of rinsing solvents
– mixing system that does not require flushing the mixer with base component “A”
– minimal residual material in the barrel – less than 1%.

EASE OF USE
– drum positioning plates facilitate correct loading
– automatic stop of pumps in case of lack of material
– hydraulically driven symmetrical piston pumps with high dosing accuracy
– precise maintenance of the preset pressure ensures an even outflow of material.

Additional optional equipment
– mobile construction on wheels
– two-piece folding swing arm
– balancer to support the application gun
– collection of component “B” from 200-litre drums
– diagnostics via wireless internet communication system
– drum roller for base component “A”.

– feeding pump comp. “A” pump with pressure plate for 200 l barrel
– positioning plate for 200 l drum, reducing residual material in the drum
– feeding pump comp. “B” with pressure plate for 20 l pail
– positioning plate for 20 litre drums to reduce the amount of residual material in the drum
– adjustable metering pump unit for components “A” and “B”
– hydraulic drive for the metering pump unit with a maximum power of 2.2 kW
– control cabinet equipped with a graphic control panel with touch screen
– electronic pressure transducers
– control and indication of lack of “A” and “B” material in drums
– mechanical dosing ratio control
• in the volumetric range 7.5:1 – 14:1 using the default dosing set 10 : 1
– the weight range will be a resultant of the individual properties of the material used, i.e. the specific weight of the individual components
– the efficiency of the plant is dependent on the viscosity of the material used, where the limiting factor is the mechanical
strength of the mixer.
• for DOWSIL 993, 3362 and 3363 silicones at 180 bar: 1.2 L / min (approx. 1.6 kg/min) with 32-element mixer
– the extrusion output of the mix is adjusted by changing the pressure parameters via a touch panel.
