Features

1. Thick sectioned pump casing and cover are injection molded from homogeneous thermoplastics. 
    
2. Key driven, dynamically balanced injection molded impeller design with stainless steel insert ensures positive drive, provides additional rigidity to impeller at higher temperatures and pressures, and prevents damage in case of reverse rotation. Semi-open or closed impellers are available. 
    
3. The award winning wide-open power frame with a retractable inboard bearing assures minimal shaft deflection and impeller overhang and facilitates easy mechanical seal inspection and readjustment. The unique pedestal design allows for the use of most commercially available mechanical seals without the need for modification. Mechanical seals are reverse mounted, exposing only the non-metallic seal faces to the fluid handled.

4. Heavy duty, self-aligning bearings widely spaced on the shaft, assure perfect alignment for maximum stability and long seal life. 
    
5. The relatively short, large diameter stainless steel shaft is sleeved with thermoplastic to isolate it from the fluid. 
    
6. 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. 
    
7. Back pullout construction per ANSI B73.1 specification, with leveling bolt to facilitate ease of maintenance without disturbing the piping.
