Abstract
The suction side performance of an injection pump for pumping a viscous chemical liquid or semi-liquid additive into a liquid flowing in a pipeline is improved by simultaneously pumping a compatible low viscosity liquid into the line leading to the suction side of the injection pump. The low viscosity liquid acts as a lubricating fluid for the viscous additive and assists movement of the viscous additive to and through the injection pump. The combined action of the low viscosity liquid and injection pump may also assist solution or dispersion of the additive in the liquid flowing in the pipeline.
