External gear pump DARTec®
The DARTec® gear pump was specifically designed for high precision dosing of thermally reactive fluids.
Its protected sealed needle bearing system eliminates material contact with bearings preventing shear and frictional heat in these areas normally associated with external gear pumps. Because of this innovation there is a notable reduction in the amount of solvent required to flush the pump and downtime between jobs. This also leads to an overall improved efficiency, typically >95%.
The DARTec® is also available in a low weight construction (700 grams) and is optimal for use on 3 and 4 axis robot dispensing equipmen
