Product Specifications

  • 25’ (8 m) of heavy duty power cord.
  • 25’ (8 m) of heavy duty sensor cord.
  • Specially designed splices and potted cord entry system provides strain relief and prevents wicking of liquids into the housing.
  • Lifting lug integral part of housing (orientation 90° from illustrated view).
  • Finned oil-filled, explosion-proof rated motor housing assures uniform heat distribution, lubricates bearings and conducts heat for cooler running.
  • 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.
  • Tandem seals. Carbon/rotating, ceramic/stationary, Buna-N elastomers.
  • Upper and lower high carbon chromium steel ball bearings.
  • Stainless steel shaft and hardware resists corrosion.
  • Patented moisture detection system with upper and lower probes, protecting the motor form liquid entry.
  • Thermal sensor will deactivate pump if internal motor temperature reaches 250 °F (121 °C).
  • Vent hole helps prevent air locking.
  • Balanced ductile iron two-vane, semi-open impeller with top pump-out vanes for seal protection keyed and bolted to shaft.
  • Concentric volute reduces radial loading for longer bearing and seal life.
  • 3” NPT vertical or 3" or 4" flanged horizontal discharge.
  • Entire unit protected with a corrosion-resistant, powder coated epoxy finish.
  • 2" male NPT conduit connection (3" vertical discharge units)
