When pumping liquids with a density and/or viscosity
higher than that of water, use motors with
correspondingly higher outputs, if required.
Whether a pump is suitable for a particular liquid
depends on a number of factors of which the most
important are chloride content, pH value,
temperature, content of chemicals and oils. Please
