Steelhead Composites lightweight 6,000 psi (414 bar) top repairable composite accumulators range in size from 10 gallons (38 liter) to 30 gallons (113 liter). Lightweight composite accumulators are a superior alternative to steel accumulators for weight-restricted uses, mobile applications and industries where access is remote, elevated or limited.
These lightweight high pressure accumulators are Aluminum lined composite pressure vessels with a rubber bladder inside. The bladder is pre-charged with Nitrogen gas before the accumulator assembly is put in to hydraulic service. A poppet valve in the fluid port prevents extrusion of the pre-charged bladder through the fluid port.
Top repairable accumulators consist of large port openings on both ends. One opening houses the hydraulic fluid port and the other the gas port. The large opening on the gas port end in a top repairable accumulator allows easy maintenance and replacement of the rubber bladder without removing the accumulator from the hydraulic line. A pneumatic valve on the gas port facilitates periodic re-charging of the Nitrogen gas in the bladder.
Advanced manufacturing processes allow for fast delivery of eight weeks or less for standard sizes and twelve weeks or less for custom accumulators.
