Due to significant changes to the materials used in paint and coatings production, the processes for manufacturing them have become a more refined science. To ensure the highest quality standards, paint and coating manufacturers must utilize high quality, reliable, robust equipment. One of the major problems for conventional pumps in delivering paint is the lack of fluidity of the medium. Continuous supply can therefore be achieved only with difficulty; in addition, the pumps become clogged quickly. Water-based, solvent-based and UV-curable inks, along with other coatings, varnishes and adhesives, are often abrasive, shear sensitive, and exhibit a wide range of viscosities (10,000+ mPas are quite common).
