Robust glass-free mag-drive pumps

December 8, 2008

The sealless mag-drive pumps are constructed from glass-free polypropylene (pp) or polyvinylidene fluoride (pvdf). Glass-reinforced thermoplastic molded pump components can be attacked and permeated by corrosive chemicals (e.g., caustics, chlorides, fluorides, bromides, etc.) due to etching and wicking of glass fibers. Robust, high density extruded thermoplastics provide three- to four-times the thickness of molded counterparts for maximum chemical resistance, even with thermal cycling. Industry exclusive integral casing flanges ensure positive sealing and zero emissions. Pump designs are available in End Suction Centrifugal, Regenerative Turbine, Self-Priming, Rotary Vane, and Vertical Sump.
