Thermoplastic Magnetically Driven Pump Now Available

Aug. 2, 2010
The pump is a sealless, single-stage, volute-type centrifugal design.

Vanton Pump introduces CHEM-GARD CGMC close-coupled, magnetically-driven thermoplastic centrifugal pump in sizes from 1.5x1x6 to 3x2x8 inches (38x25x152 to 76x51x203 mm) for flows to 400 GPM (91m3/hr) at heads to 220 feet TDH (50m).

The pump is a sealless, single-stage, volute-type centrifugal design with all fluid contact components molded of homogenous polypropylene or PVDF. These standalone, chemically inert, abrasion-resistant thermoplastic components eliminate pinpoint porosity, substrate separation and wear associated with plastic lined pumps.

An addition to the company’s CHEM-GARD line of conventionally coupled CGM magnetically driven 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. Permanent rare-earth magnets transmit power, with the inner magnet rotor assembly encapsulated in thick-walled thermoplastic. A nonmetallic containment can assembly reduces losses in magnetic force and pump efficiency by eliminating troublesome eddy currents.

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.
