A Chem-Gard CGMC close-coupled, magnetically-driven thermoplastic centrifugal pump in sizes from 38 x 25 x 152 to 76 x 51 x 203 mm for flows to 91m3/hr at heads to 50m TDH, has been introduced by Vanton Pump.
The pump is a sealless, single-stage, volute-type centrifugal design with all fluid contact components moulded 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.
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 per cent, 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 non-metallic 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 armour 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.
