Vanton CHEM-GARD® CGM magnetically driven end suction process pumps are sealless, single stage, volute type centrifugals that conform to Hydraulic Institute Standards. All fluid contact parts are molded of solid polypropylene (PP) or polyvinylidene fluoride (PVDF), which are chemically inert and abrasion resistant. As a result CGM pumps eliminate corrosion associated with metal pumps, wicking and contamination associated with fiberglass pumps, and porosity/delamination associated with plastic lined metal pumps.
