What is a custom hydraulic accumulator?

A custom hydraulic accumulator is designed and configured to meet specific hydraulic-system requirements that may not be satisfied by a standard accumulator. Customization can include pressure rating, capacity, shell and bladder materials, fluid connections, gas valves, dimensions, mounting options, and required certifications. FEC provides custom accumulator solutions for specialized hydraulic and fluid-power applications.

Can FEC customize hydraulic accumulators for specific pressure and capacity requirements?

Yes. FEC can provide custom hydraulic accumulators across different pressure and capacity requirements. The custom accumulator range includes design pressures from 225/250 PSI up to 3,000 PSI and capacities from 1 Qt to 120 Gal (1 L to 500 L). Special sizes, materials, pressure ratings, and connections are also available upon request.

What materials are available for custom hydraulic accumulators?

FEC offers custom accumulator configurations using Buna-N, Viton, EPR, Hydrin, and Butyl bladder materials, with shell options including carbon steel, 304 stainless steel, and 316 stainless steel. Material selection should be based on the hydraulic fluid, operating temperature, pressure, corrosion requirements, and application conditions.

What certifications are available for custom accumulators?

FEC custom accumulators can be supplied with certifications including ASME Section VIII Division 1, CE/PED, CRN, NR-13, SELO, DOSH, and AS1210. Other certifications may also be available depending on the application and project requirements.

How do I specify or order a custom hydraulic accumulator?

To specify a custom hydraulic accumulator, provide the required working and design pressure, accumulator capacity, hydraulic fluid, operating temperature, bladder material, shell material, fluid connection, gas valve, mounting requirements, dimensions, and required certification. FEC can then determine a suitable configuration based on the application's technical requirements.
