CHEM-GARD^® CGM

1. Dual non-metallic containment can assembly with a thermoplastic inner can to resist corrosive fluids, backed by a rigid non-metallic composite outer can. This construction avoids troublesome eddy currents and enhances efficiency.
    
2. Thermoplastic sleeve assembly completely isolates the large diameter stainless steel shaft from the fluid.
    
3. Pump casing, inner magnet bearing housing and impeller are molded from homogeneous, virgin thermoplastics (polypropylene or polyvinylidene fluoride). Metal armor provides structural protection and permits the pump to withstand the same nozzle loadings as metal pumps.
    
4. External cast iron protective armor, which also serves to carry the nozzle loadings, is coated with a chemical resistant two-part epoxy paint to guard against chemical and atmospheric corrosion.

5. High performance permanent rare-earth magnets offer power ratings to 30 hp at 3600 rpm for flow rates to 400 gpm (91 m³/h) at heads to 180 ft (55 m). The pumps are recommended for service at temperatures to 225°F (107°C).
    
6. High PV stationary bearings and rotating sleeve/thrust bearings of silicon carbide are standard. Ultrapure alumina ceramic and other materials are available as options.
    
7. Dynamically balanced, closed vane thermoplastic impellers with molded-in stainless steel inserts to assure rigidity, and are key locked to the shaft.
    
8. Wide-open fluid passages provide for continuous flow of liquid for cooling and lubricating the sleeve/thrust bearings.
    
9. Drive shaft bearing housing is furnished with heavy duty, sealed, grease-lubricated ball bearings.
