Design Considerations

• Bearing Assembly and Shaft

  • The shaft is designed with a short overhang to:
    • Reduce shaft deflection
    • Minimize vibration
  • Provided with hardened shaft sleeve to protect the shaft
  • The bearing assembly is retained on a one-piece frame
  • Grease-purged piston rings to help seal contaminates out of bearing housing

• Impeller

  • Enclosed are impellers to maximize efficiency
  • Pump-out vanes on both shrouds
    • Minimises re-circulation
    • Reduces stung box pressure
  • High chrome liquid ends
  • Interchangeable hard metal impellers
  • Impeller clearance is set by moving the bearing assembly
  • High-efficiency impeller optional

• Single Casing with Assembly Clamps

  • Easy assembly and disassembly of liquid end
  • Clamp design facilitates rotation of volute
  • Large volute reduces friction and wear
  • Minimal parts + simple design

• Centrifugal Seal Option

  • Reduces or eliminates the need for gland service water
  • Reduces sleeve wear and possible bearing contamination
