PneuDraulics, Inc. (PDI) is a leading manufacturer and supplier of hydraulic accumulators for the aerospace industry. Hydraulic accumulators are devices that use pressurized nitrogen to maintain adequate pressure in the hydraulic system. They are often useful for maintaining reserve system pressure levels during short-term system shutdowns.

PDI offers a range of aerospace hydraulic accumulator designs in volumes from 10 to 400 cubic inches. PDI designs meet the latest Part 25 requirements for 4 times operating for burst pressure. They can be provided with charging valve and pressure gauge. Some designs utilize a PDI proprietary equalization device which further minimizes pneumatic pressure losses over the life of the aircraft.

PDI’s aerospace hydraulic accumulators are used worldwide on various airframes, such as Bombardier CRJ NextGen, COMAC ARJ21, Gulfstream G450/G550, Gulfstream G650, and Sukhoi Superjet 100. PDI’s hydraulic accumulators are known for their high quality, performance, and reliability.
