Advantages of the Sundyne LMV (Line Mounted Vertical) Pump Line
Sundyne API 610, OH6 Integrally Gear Driven Pumps are engineered for critical high-head, low-flow, heavy-duty services required in the hydrocarbon, chemical, petrochemical, power generation, gas production, and specialty processing industries.


Features and Benefits
  • 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.

  • Simplifies maintenance
  • Minimizes downtime
