Machine description Machine description The DUOMIX PU 460 is a 2-component coating machine for industrial use. Seam- less and smooth coatings and linings can be applied using this machine. Due to the fixed mixing ratio of the pump, the exact dosing of both components is ensured at all times. Every mixing ratio from 1:1 to 10:1 can be realised with a simple exchange of the material pumps.

Machine description 3.9 Intermediate piece The intermediate piece connects the DUOMIX PU 460 to the hose assembly. The two manometers display the current material pressure of each of the components. These values are also displayed on the touchscreen. Balls valves, which are used for opening and closing the ventilation or the pressure relief, can be present as an option.
Through the material circulation, the air that is located in the material circuit after filling is pressed out via the return hoses, whereby a bubble-free material flow is ensured. Since in the process the material passes the material fluid heater again and again, a uniform temperature distribution is furthermore ensured.
