A Better, Faster Way to Source Pumps

Vanton introduces new centrifugal pump

Vanton Pump has introduced a new CHEM-GARD CGMC close-coupled, magnetically-driven thermoplastic centrifugal pump in sizes from 1.5x1x6 to 3x2x8 in. (38x25x152 to 76x51x203 mm) for flows to 400 GPM (91m3/hr) at heads to 220 ft TDH (50m). The pump is a sealless, single-stage, volute-type centrifugal design. All of its fluid contact components are made from 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. Vanton's new CHEM-GARD pump is an addition to the New Jersey-based company's 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, according to a news release from Vanton. Permanent rare earth magnets transmit power, with the inner magnet rotor assembly encapsulated in thick-walled thermoplastic. A non-metallic containment can assembly eliminates problematic eddy currents, reducing the losses in magnetic force and pump efficiency.

Available with ANSI centerline suction and discharge, the pump allows removal for maintenance without disturbing existing piping. It 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. This allows the pump to withstand hostile environments and tolerate the same nozzle loadings as metal pumps.
