APPLICATIONS

  • Pumping stations
  • Storm water removal
  • Wastewater transfer
  • Industrial wastewater

PUMP:

  • Solids – 2-1/2” (63 mm) spherical capability
  • Discharge: 3” NPT vertical or 3" or 4" flanged horizontal
  • Seals – dual mechanical carbon/rotary ceramic/stationary, Buna-N elastomers
  • Construction – cast iron ASTMA 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
  • O ring seals – Buna-N
  • Ductile iron impeller – 2-blade, semi-open with top pump-out vanes
  • Optional:
    • Thermal sensor and moisture detection system
    • Trimmed impeller
    • Vortex impeller
    • Bronze impeller
    • 3" (76 mm) solids capacity (4" discharge units only)
    • Silicon carbide seal(s)
    • Additional cord length
    • 3450 RPM high head unit (3" discharge unit only)
    • High temperature construction (1-3 BHP, not CSA listed)
    • Dry pit configuration
    • Inverter duty motor (1-5 BHP, not CSA listed)
    • Rail systems

MOTOR:

  • Stator – Class F insulation and lead wires, NEMA B design
  • Oil-filled, cast iron motor housing
  • Finned cast iron housing for faster heat dissipation
  • Ball bearings – dual high carbon chromium steel
  • Power cable length – 25’ (8 m)
Note: Product information presented here reflects conditions at time of publication. Consult factory regarding discrepancies or inconsistencies.

  1. 25’ (8 m) of heavy duty power cable.
  2. Protected cable entrance. The compression grommet allows for field-replacement of the cable.
  3. Each conductor is individually sealed to eliminate cord wicking of liquids.
  4. Lifting lug integral part of housing.
  5. Oil-filled motor housing assures uniform heat distribution, lubricates bearings and conducts heat for cooler running.
  6. Heavy-duty 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. Optional: Patented moisture-detection system with upper and lower probes, protecting the motor from liquid entry.
  11. Optional: Thermal sensor protection. Motors have two, normally closed temperature sensors imbedded in windings.
  12. Optional: 25’ (8 m) sensor cable.
  13. Balanced ductile iron, two vane, semi-open impeller with top pump out vanes for seal protection. Keyed and bolted to shaft.
  14. Concentric case reduces radial loading for longer bearing and seal life.
  15. 3” NPT vertical discharge or 3" or 4" flanged horizontal discharge.
  16. Vent hole helps prevent air locking.
  17. Units protected with corrosion-resistant, baked-on epoxy powder coating.
