Volume flow
3)
0.2 to 12 ml/min
1)
max. dosing pressure and self-sealing decrease with decreasing viscosity and increase with
increasing viscosity. Consult manufacturer.
2)
volumetric dosing as absolute deviation relative to one dispenser rotation. Depending on the
viscosity of the dosing medium
3)
max. volume flow is dependant on the viscosity, primary pressure and mix ratio
4)
dependant on the mixing pipe
