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.

High performance, permanent, rare-earth magnets transmit power, with the inner magnet rotor assembly isolated from the pumped fluid by a thick-walled PP or PVDF encapsulation. A non-metallic containment can assembly

 reduces losses in magnetic force and pump efficiency by eliminating troublesome eddy currents.

With no seals to fail, and no metal contacting the fluid, these pumps are ideal for leak proof transfer of corrosive, toxic, hazardous and volatile liquids, and for handling of high purity water, reagent grade chemicals and other fluids that must remain contamination free.

CGM pumps can withstand the same nozzle loadings as metal pumps because the rugged thermoplastic wet end is supported by a protective structural metal armor.

Available with ANSI centerline suction and discharge, CGM pumps fit where conventionally sealed ANSI pumps were installed, without disturbing existing piping.

The wet end is comprised of solid, thick-sectioned, stand-alone components (unlike plastic linings), that are easily replaced, maximizing uptime while minimizing cost.
 
The heavy-duty pump casing, stationary bearing housing and impeller are furnished in solid molded polypropylene and polyvinylidene fluoride. The inner magnet rotor assembly is encapsulated in PVDF or polypropylene, and the stainless steel large diameter shaft is isolated from the fluid by a thermoplastic sleeve assembly.
