Rugged high precision metering head with variable mix ratio for manual and automated dispensing application
The DOI is a volumetric metering head with gear pumps, designed to work with one- or multi-component non-abrasive materials of medium to high viscosity. It meters and mixes with high precision at different flow rates, keeping a constant mix ratio thanks to the real-time interpolation of the driving motors.
The mechanical construction made of wear&tear resistant steel is rugged and reliable, also thanks to the lubrication system of the gear pump axle seals and the diaphragm valves for anti-dripping protection; pressure sensure for material feeding and stepper motors with enclosed loop controllers make the DOI a leader in precision and repeatability.
