Viscosity is the toughness of a liquid, e.g. of caustic soda. High viscosity means thickness, in contrast to low viscosity which means fluidity.

Thin = low viscous; small numercial value

Thick = high viscous; large numerical value


Water = 1 mPas

Thick oil = approx. 2,000 mPas

Glycerin (pure) = 1,480 mPas

Olive oil = approx. 100 mPas

Honey = 10,000 mPas

If you want to dose liquids with a viscosity > 3,000 mPas, more parameters for the selection of the pump are essential. Feel free to contact us.
