Thermoplastic Close-Coupled Mag-Drive Pump Reduces Footprint, Eliminates Corrosion, Contamination

August 2, 2010
The close-coupled, magnetically driven thermoplastic centrifugal pump ranges in sizes from 1.5x1x6 to 3x2x8 in. for flows to 400 GPM at heads to 220 ft TDH. The pump is a sealless, single-stage, volute-type centrifugal design with all fluid contact components molded of homogenous polypropylene or PVDF. These stand-alone, chemically inert, abrasion-resistant thermoplastic components eliminate pinpoint porosity, substrate separation and wear associated with plastic lined pumps. The close-coupled CGMC design reduces overall length by approximately 20 percent, allowing placement in restricted spaces typically encountered in replacement and OEM applications. Available with ANSI centerline suction and discharge, the pump allows removal for maintenance without disturbing existing piping, and can accommodate standard C-face motors. The thermoplastic wet end is encased by structural metal armor that is protected by a chemical resistant epoxy coating, enabling the pump to withstand hostile environments and tolerate the same nozzle loadings as metal pumps.
