Product Specifications

  • 25’ (8 m) of heavy duty power cable.
  • Heavy wall conduit threads and strain relief grommet for cable protection.
  • Protected cable entrance. The compression grommet allows for field replacement of the cable and each conductor is individually sealed to eliminate cord wicking of liquids.
  • Lifting lugs integral part of housing.
  • Oil-filled stainless steel motor housing assures uniform heat distribution, lubricates bearings, and conducts heat for cooler running.
  • 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 (155 °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.
  • Seal leak detector probes.
  • Thermal sensor protection.
  • 25’ (8 m) sensor cable.
  • Balanced ductile iron 2 vanes closed impeller with top & bottom pump out vanes for seal protection keyed and bolted to shaft.
  • Concentric case reduces radial loading for longer bearing and seal life.
  • 4" or 6" flanged horizontal Class 125 discharge.
  • Unit protected with a 2-part corrosion resistant epoxy coating.
  • Wear ring (4" discharge only)
