*1: Maximum dosing pressure and specific air-tightness vary in proportion to the change in viscosity. Check on the manufacturer’s recommended values.
*2: Volumetric dosage dispensed as an absolute deviation per dispenser rotation. It varies according to the viscosity of medium to dose.
*3: Volume flow rate varies according to the viscosity and initial pressure.
