Description of MK 825 PLUS



  • Sensor-controlled 2-component mixing head with high-pressure water rinsing and dynamic mixing of liquid to highly viscous polymeric reaction materials for foam gasketing, bonding and potting processes

  • High-pressure water rinsing for ecological cleaning of the mixing chamber

  • Alternative: rinsing with A-component 

  • Servopneumatically and hydromechanically controlled precision valves for precise dosing

  • Can also be equipped with stub lines for bonding or potting applications

  • Weight-reduced construction of a modular design, blue-gray anodized







  • Size-optimized, functional V design to increase the degrees of freedom

  • Robust and maintenance-free design made of high-strength aluminum alloy and chrome steel

  • Direct stack injection of the components

  • Electronically adjustable stirrer speed

  • Special stirrer design enables gentle material mixing

  • Blowing air needle valve for drying the mixing system

  • Low-drip, low-maintenance nozzle shut-off system STOP-DROP DVS 3

  • Simple stroke adjustment by means of an adjusting wheel

  • Material pressure measurement at the dosing valve

  • Mixing chamber temperature sensor
