DOI

Rugged high precision metering head with variable mix ratio for manual and automated dispensing application

The DOI system is a volumetric metering head with gear pumps, designed to work with single 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 sturdy and reliable, thanks to the lubrication system of the gear pump axle seals and the diaphragm valves for anti-dripping protection. Pressure sensors for material feeding and stepper motors with enclosed loop controllers make the DOI a leader in precision and repeatability.
