    2. Modular Pump Design
      • Commonality of parts across the pump product line minimizes the amount of parts required for servicing
      • Heavy duty ASTM A48, Class 30 Cast-Iron components
    3. Strong Motor
      • High torque for powerful (208/240V) and reliable pump operation
      • Pressed stator securely holds motor and efficiently transfers heat
      • Class F insulation with overload protection in oil filled chamber for cool operation and long motor life
    4. Internal Start Kit
      • Start/Run capacitor with relay securely positioned in dry compartment
      • Rubber compression grommet for wire leads to motor prevents oil from entering chamber
      • 4 bolts quickly removes cord cap for easy servicing
    5. 3-Bearing Support
      • Motor/Pump shaft securely held with upper and lower ball bearing plus addition sleeve bearing in lower seal chamber
