ANSI Thermoplastic Magnetically Driven Sealless Centrifugal Pumps - Vanton CHEM-GARD CGM®
CHEM-GARD® CGM ANSI Thermoplastic Magnetically Driven Sealless Centrifugal Pumps
Vanton CHEM-GARD® CGM-ANSI magnetically driven end suction process pumps are sealless, single stage, volute type centrifugals which meet ANSI B73.1 process pump specifications and conform to Hydraulic Institute Standards. They are designed to reflect the latest clean air regulations, to be environmentally safe, and to provide for the leakproof transfer of corrosive, toxic, hazardous and volatile liquids. These are not lined pumps. All fluid contact parts are made of solid, molded, stand-alone, chemically inert thermoplastic components. This avoids inherent liner-related dangers of pinpoint porosity, substrate separation due to faulty application or differential expansion, and surface abrasion.
Power is transmitted by high performance permanent rare earth magnets, with the inner magnet rotor assembly encapsulated in PVDF or polypropylene. The Vanton design utilizes a dual nonmetallic containment can assembly consisting of a fluoropolymer for the inner can in direct fluid contact, backed by a rugged composite rigid outer can. This avoids troublesome eddy currents that reduce pump efficiency by loss of magnetic force. Maintenance costs and spare parts inventory are minimized by the fact that CGM pump sizes use interchangeable components.
These sealless pumps are ideal for handling a broad range of corrosive and hazardous liquids used in chemical, pharmaceutical and other process industries, and for safe-guarding the environment through leak-free transfer of aggressive fluids generated by industrial or municipal wastewater treatment. Since the rugged thermoplastic casings are additionally protected by structural metal armor, these pumps withstand the same nozzle loadings as metal pumps and their conformance to ANSI specifications permits direct replacement of conventional mechanically sealed centrifugal pumps.
