Parker Aerospace gearbox-driven scavenge pumps use gerotor technology to provide unique positive displacement solutions of all shapes and sizes to meet customer needs. These pumps are used for airplanes and helicopters to scavenge the lubricating oil from main gas turbine engine back to the reservoir.

Gerotor is a “generated rotor” pump and consists of an inner and outer rotor that both rotate on their axes. These are a robust, reliable, proven non-risk choice that outlasts the gear, vane, or piston pumps.

Parker Aerospace has decades of experience in design and manufacture these gearbox-driven scavenge pumps. That experience allows creation of the customized, smallest, most compact, lightweight, and reliable solution for the application.

APPLICATIONS:
Parker Aerospace gearbox-driven scavenge pumps are used on the main gas turbine engine lubricating systems in commercial and military applications of aircraft engines by such industry stalwarts as General Electric, Pratt and Whitney, Rolls Royce, Bell Helicopter, Boeing Rotorcraft, Agusta, Eurocopter, and Sikorsky.

FEATURES AND ATTRIBUTES:
• Gerotor pump typically require less axial length then other positive displacement pumps
• Gerotor pumps are typically lighter than gear, vane or piston pumps
• Parker currently over 25 unique gerotors curves to meet fluid mechanics constraints

OPTIONAL FEATURES:
Parker Aerospace’s vast experience with these gearbox-driven scavenge pumps allows a variety of custom applications of gerotor technology to meet application requirements.
