The 3P211 Pesco Vacuum Pump is a historical gem, hailing from the golden era of aviation during World War II. This vacuum pump was designed and manufactured for use in warbird aircraft, specifically those in the Boeing B-17 Flying Fortress, B-24 Liberator, B-29 Superfortress, and C-46 Commando and C-54 Skymaster fleets.
The 3P211 Pesco Vacuum Pump is a testament to the era's engineering prowess and the relentless pursuit of technological advancement in aviation.

It features a single-stage, gear-driven design with a hand-operated crank, making it easy to use and maintain even in the rugged conditions of a wartime aircraft.
The pump measures approximately 20 inches in length, 8 inches in width, and 10 inches in height, with a weight of around 30 pounds. It is equipped with a steel intake and exhaust valve, as well as a cast iron oil reservoir to lubricate the gears and reduce wear and tear.
The 3P211 Pesco Vacuum Pump is a fascinating piece of aviation history, and a must-have for any collector or enthusiast of vintage warbird aircraft. Whether you're restoring a B-17 Flying Fortress or simply looking for a unique and authentic addition to your collection, the 3P211 Pesco Vacuum Pump is sure to impress.
