Three-Circuit Lubrication and Scavenge Pump P-056


Bearing Lubrication and Scavenge for FT8 Power Turbine | Leading Gas Turbine Engine Manufacturer

Benefits & Features

The extended operating life of this aero-derivative machine meant that the lubrication system would need to compensate for seal wear over tens of thousands of run hours.  Capable of managing a 30:1 air-to-oil ratio and fluid temperatures above 300 °F, this multi-circuit pump now supports hundreds of electrical generation and mechanical drive installations around the world.

  • Durable ductile cast-iron casings
  • Reliable gerotor technology
  • Case-hardened steel pump elements
  • Single hardened steel shaft
  • Integral relief valve
  • Capable of high air-to-oil scavenge ratios
