HYDRAULIC ACCUMULATORS

The Hydraulic Systems Division designs and manufactures a complete line of accumulators for aerospace and derivative markets. Our accumulator product line is designed to meet stringent weight, envelope, and performance requirements.       

 

Our accumulators are designed for minimum weight and maximum volumetric capacity. The units incorporate various seal configurations to provide high endurance and to withstand high pressure fluctuations without extrusion or spiral failures. A number of our accumulators incorporate single end caps as well as synthetic composite wraps for additional weight savings. We also provide double end cap accumulators designed in accordance with MS28700 and MS28797.

 

Our extensive heritage and broad product offerings mean we have the capability to design and build custom accumulators for your application.
