Product Specifications
- 25’ (8 m) heavy duty power cable.
- Protected cable entrance.
- Each conductor is individually sealed to eliminate cord wicking of liquids.
- Lifting lug integral part of housing (orientation 90° from illustrated view).
- 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 from liquid entry.
- Thermal sensor protection.
- 25’ (8 m) sensor cable.
- Ductile iron vortex impeller design, bronze optional, fully balanced with integral pump out vane to clear debris.
- “Star” type stainless steel cutter and plate hardened to Rockwell C55-60.
- Concentric case reduces radial loading for longer bearing and seal life.
- 2-1/2” flanged horizontal discharge adaptable to 3” flange. Optional 2” NPT vertical discharge available for HH and HF models.
- Vent hole helps prevent air locking.
- Screw on pipe legs for field flexibility.
- Class 30 cast iron housing protected with corrosion-resistant, baked-on epoxy powder coating.
- Finned motor housing for quicker heat dissipation.
