Covered by U.S. patent number 6,364,620.

APPLICATIONS

  • Sewage lift stations.
  • Housing developments.
  • Low-pressure sewer systems.
  • High vertical lift or long force mains.

PUMP:

  • 440 stainless steel cutter and plate hardened to Rockwell C55-60.
  • Discharge size - 2-1/2" flanged horizontal adaptable to 3" flange, 2" NPT optional.
  • Seals - dual mechanical carbon/rotary ceramic/stationary, Buna-N elastomers.
  • Moisture detection system.
  • Construction - Cast iron ASTM A-48, Class 30, 30,000# tensile strength, protected with a corrosion-resistant, baked-on epoxy powder coating.
  • Balanced concentric pump housing and impeller.
  • Attaching hardware - 304 stainless steel.
  • Square ring seals - Buna-N.
  • Impeller - Ductile iron vortex design.
  • Optional:
    • Trimmed impeller
    • Silicon carbide seals
    • 50' (15.2 m) power cord and sensor cables
    • Bronze vortex impeller
    • Viton square ring seals
    • 2" NPT discharge (high head and high flow models only)
    • High flow
    • Automatic reversing (3 Ph flanged models only)
    • Non-sparking rail systems

MOTOR:

  • FM and cCSAus rated Class 1, Division 1, Group C & D construction.
  • Stator – Class F insulation and lead wires. NEMA B design.
  • Thermal sensor and leads.
  • Housing - cast iron, oil-filled.
  • Ball bearings – upper and lower high carbon chromium steel.
  • Power and sensor cable length: 25' (7.6 m).

Note: Product information presented here reflects conditions at time of publication. Consult factory regarding discrepancies or inconsistencies.

  1. 25’ (8 m) heavy duty power cable.
  2. Protected cable entrance.
  3. Each conductor is individually sealed to eliminate cord wicking of liquids.
  4. Lifting lug integral part of housing (orientation 90° from illustrated view).
  5. Oil-filled, explosion-proof rated motor housing assures uniform heat distribution, lubricates bearings and conducts heat for cooler running.
  6. Heavy-duty, explosion-proof rated motor features ball bearing construction. Class F motor insulation is double-dipped and baked. End connections and lead wires are Class F. At maximum load, winding temperature will not exceed 250° F (121° C) with motor housing not submerged.
  7. Tandem seals. Carbon/rotating, ceramic/stationary, Buna-N elastomers.
  8. Upper and lower high carbon chromium steel ball bearings.
  9. Stainless steel shaft and hardware resists corrosion.
  10. Patented moisture detection system with upper and lower probes, protecting the motor from liquid entry.
  11. Thermal sensor protection.
  12. 25’ (8 m) sensor cable.
  13. Ductile iron vortex impeller design, bronze optional, fully balanced with integral pump out vane to clear debris.
  14. “Star” type stainless steel cutter and plate hardened to Rockwell C55-60.
  15. Concentric case reduces radial loading for longer bearing and seal life.
  16. 2½” flanged horizontal discharge adaptable to 3” flange. Optional 2” NPT vertical discharge available for HH and HF models.
  17. Vent hole helps prevent air locking.
  18. Screw on pipe legs for field flexibility.
  19. Class 30 cast iron housing protected with corrosion-resistant, baked-on epoxy powder coating.
  20. Finned motor housing for quicker heat dissipation.
