Recessed Impeller Pump for grit, primary sludge, digested sludge, scum; Hayward Gordon

Hayward Gordon – TORUS® Recessed Impeller pump is a centrifugal pump with a radial impeller recessed into the rear section of the volute, out of the path of the solids being pumped. This impeller uses about 15 percent of the fluid being pumped to create a torus or vortex thus adding energy to the pumped fluid-solids. Features Ni-Hard (650 BHN) hard construction ideally suited for highly abrasive applications, grit, slurries with gas entrainment, and for stringy or fibrous materials. The recessed impeller creates a vortex within the casing which traps the solids and expels them from the pump with minimal impeller contact.

Ideal applications include:

  • Grit
  • Primary sludge
  • Digested sludge
  • Scum
  • Lime sludge
  • Fly ash
