Product Specifications

  • Rigid steel lifting handle.
  • Thermal sensor protects motor from overheating.
  • Finned cast iron housing for maximum heat dissipation. Registered machine fits and positive sealing O ring seals at all joints; easy replacement.
  • High efficiency, air-filled, press-fitted Class H rated motor for continuous duty applications. Optional FM rated for Class 1, Division 1, Group C & D hazardous duty environments.
  • Permanently lubricated, heavy-duty thrust bearing; locked to prevent axial movement.
  • 304 stainless steel fasteners provided throughout assembly.
  • Type 21 tandem (dual) silicon carbide shaft seal system. Provides high resistance to abrasion and corrosion over a wide range of temperature extremes.
  • 50’ long type SEOW-A power and control cables resist rough handling and abrasion.
  • Large cap/cable chamber with terminal board for lead connections. Neoprene grommet and complete epoxy encapsulation provide for a true non-wicking cable entry. An isolating cable chamber is not needed.
  • Permanently lubricated, heavy-duty radial bearing with expansion area for bearings provides clearance for rotor/pump shaft expansion.
  • One-piece, solid stainless steel shaft with short shaft overhang.
  • Two-wire/two-probe moisture detection system ensures a positive current path to and from probes; eliminates false alarms.
  • Sealed oil chamber, isolating the motor housing from the pump housing.
  • Enclosed 3” (76 mm) solids-handling impeller with stainless steel wear ring having large flow paths, designed for high efficiencies, trimmed and balanced to meet specific design conditions.
  • Pump housing with 4” or 6” flanged horizontal discharge and wear ring.
