Abstract

The invention is a piezoelectric self-cleaning apparatus, such as a chemical injection pump. The chemical injection pump is self-cleaning by employing either as an integral part or as an added part, a piezoelectric component that implosively cleans the pump head. This invention involves a liquid delivery system made of a liquid processing path and a piezoelectric actuator connected to or integral with said liquid processing path to enhance removal of unwanted solids from the liquid processing path or to maintain a blend, mix and/or integrity of a liquid chemical, wherein the liquid chemical does not precipitate particles, crystallize, separate or come out of solution.
