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