Pure PTFE (ETFE) is inert to most chemicals, and has good abrasion resistance. PTFE lined casing and containment shell with solid PTFE impeller provide superior corrosion resistance and long life unequalled by alloy pumps.
The 3298 is a sealless magnetic drive pump which is environmentally safe. No mechanical seal assures total zero leakage on moderate to severe corrosives, hazardous liquids. The 3298 offers users an economical design to meet emission standards or as a solution to pumps with mechanical seal problems.
Unlike most magnetic drive pumps, the 3298 is as easy to operate as any standard ANSI pump. Non-metallic construction with no heat build-up makes the 3298 ideally suited for tank transfer, tank type unloading or any batch type service.
The 3298 is available in close-coupled (top image) or frame-mounted (bottom image) designs for true installation or pump replacement flexibility. Since the 3298 meets ANSI dimensional standards, retrofitting mechanically sealed ANSI pumps is easy: simply replace the old pump with the equivalent close-coupled or frame-mounted ANSI size 3298.
The impeller is fitted with a carbon-filled TEFLON wear ring as standard (Pure TEFLON optional). Wear ring protects and prevents damage to impeller and critical areas of containment shell in unlikely event of bearing failure. Controls axial thrust for maximum bearing life.
Enclosed design minimizes axial thrust, extends thrust bearing life. One-piece construction eliminates front shroud failure possible with two-piece impellers. Neodymium iron magnets are completely sealed within impeller assembly.
The 3298 design concept is simple - few parts and only one bolt size.
