Vanton CHEM-GARD® thermoplastic heavy-duty pumps are designed and constructed to maximize the unique properties of solid, homogeneous, chemically inert thermoplastics. Engineered to efficiently and safely handle corrosive, abrasive, and other aggressive fluids, Vanton pumps are also ideally suited to handle deionized and ultrapure water, pharmaceuticals, reagent grade chemicals and any fluid that must remain free from metallic contamination. Mechanical seals are reverse mounted to assure no metal-to-fluid contact.
