PneuDraulics, Inc. (PDI) designs and manufactures high‑performance aerospace hydraulic accumulators used in commercial and military aircraft. These accumulators store energy using pressurized nitrogen to maintain system pressure, support emergency operation, and stabilize hydraulic performance during peak demand or temporary system shutdowns.

Hydraulic Accumulator Solutions

PDI offers a range of accumulator designs from 10 to 400+ cubic inches. Our aerospace accumulators meet the latest Part 25 burst requirements and exceed endurance requirements by 4x. Our parts can also be supplied with charging valves and pressure gauges for simplified maintenance monitoring.

These parts can integrate proprietary PDI equalization devices that minimize pneumatic pressure loss over the aircraft’s service life, as well as optional LVDT position sensing for precise monitoring of hydraulic fluid volume and accumulator performance.

Applications & Performance

PDI aerospace hydraulic accumulators are known for their reliability and long‑term durability. They support critical aircraft functions such as braking, hydraulic pressure stabilization, and emergency hydraulic reserve capacity across a broad range of aerospace platforms.
