Seven Circuit Lubrication and Scavenge Pump

Large Aero-Derivative Gas Turbine Engine Lubrication and Scavenge | Leading Gas-Turbine Engine Manufacturer

P-147, 147-D-001, 147-D-301

Features & Benefits

Our customer wanted a rugged, industrial grade, scalable solution for the lubrication and scavenge needs of their newly introduced 58 MW aero-derivative gas turbine engine.  The pump would need to mount on the engine gearbox where the more expensive and less flexible aerospace pump was previously installed so compactness and weight were still a consideration.

  • Seven independent pumping functions: oil supply for gas generator bearing lubrication and six independent scavenge circuits for each of the engine bearing compartments
  • Shell-mold castings based pump casings
  • Integrated magnetic chip detector and strainer assemblies
  • Ports for resistance temperature detector (RTD) sensors
  • Gearbox mount with quick attach/detach V-Band flange connector per MS3333-2
  • Splined input shaft with replaceable shear section designed to protect against torque overloading of the gearbox
