What is HVD? Can a Mitani product be used for a product with any level of viscosity?
HVD stands for high viscosity dispenser, a pump system including the bottle for high viscosity contents. We call it “airless pump”, a pump system using a vacuum produced by lifting the bottom of the bottle. As far as we know, this pump can be used on contents with extremely high viscosity, up to about 20,000 cP(g/(cm.s)). However, it does depend on the specific gravity and other factors of the contents as well. Please send us a sample of your contents and let us know the purpose of use. We will carry out compatibility tests and inform you of the results.
