HYDAC SBO250-0.075E1/112U-250AK diaphragm accumulator, 0.075 L

The HYDAC SBO250-0.075E1/112U-250AK is a rechargeable welded diaphragm accumulator, factory article 3041890. It stores hydraulic energy by separating the gas chamber from the fluid with a flexible diaphragm and can support pressure holding, pulsation damping and short-duration energy supply.

This article has a nominal accumulator volume of 0.075 L and a factory-card maximum allowable working pressure of 250 bar. Its diaphragm is NBR (Buna N); the shell and fluid port are Carbon steel. Nominal volume is not the usable oil delivery volume, which depends on gas precharge and operating pressures.

The factory card lists a BSPP female fluid connection, but its two port-size fields disagree; the connection size requires confirmation. The rechargeable gas valve uses an M28 × 1.5 interface. The listed flow and dimensional values are article-card data. Any fluid-qualified temperature attributes describe the diaphragm compound only; the complete assembly temperature envelope also depends on its materials and fluid. Gas precharge is not specified here and cannot be inferred from the model suffix. Mounting and commissioning must follow the SBO technical sheet; the factory range photograph is representative and may show a different size.
