Gearbox

• Reliable proven gearbox
  
  
  
• Excellence in design, manufacturing and quality
  
  
  
• Output shaft supported by plain or tilt-pad journal bearings
  
  
• Pinion shaft assembly designed for minimum bearing span to overhang ratio (L/D)
  
  
• Self-contained lube system
  
  
  
  
  
  
  
  
  
  
  
  
  
• Gearbox Exchange Program

• Thousands of units installed since 1962 with outstanding service
  
  
• AGMA Class 11 Gears
• Wide range of ratios enabling impeller speed to be matched to process requirements
  
  
• Stable rotordynamics
  
  
  
• Reduced radial loading
• Low vibration
  
  
• Reliable, trouble-free operation is obtained from the integral lubrication system which provides controlled pressurized oil flow to the bearings and gears.  The lubrication system includes a wet sump, integral oil filter and internal positive displacement pump which is driven by the input shaft.  Additional items such as auxiliary pre-lube oil pump (required on some configurations, heat exchanger (water or air), pressure/temperature switches, vibration detection system, etc. are also available.
