Seven-Circuit Multi-Circuit Gas-Turbine Engine Pump

Bearing Lubrication & Scavenge and Variable Inlet Guide Vane Actuation for 7.9 MW Gas Turbine | Leading Gas Turbine Engine Manufacturer

P-057, 57-D-003

Features & Benefits

This aero-derivative gas-turbine engine is targeted at marine propulsion applications where space is at a premium.  This multi-function pump was designed to mount directly to the engine gearbox and pull lube oil from a reservoir that could be located well below the engine in deep-V hull installations.  Engine shutdown protocols required that scavenge circuits be designed to operate with 100% gas for extended periods of time.

  • Durable ductile cast-iron casings
  • Optional gearbox and electrical drive arrangements
  • Integral relief valves
  • Hardened steel gerotor technology
  • Single hardened steel shaft
