Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
Commonly used trade names and technical identifiers for Hydraulic Accumulator.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 350 bar (standard), up to 700 bar (high-pressure variants) |
| flow rate: | Dependent on accumulator size and pre-charge pressure, typically 5-500 L/min |
| temperature: | -20°C to +80°C (standard), -40°C to +120°C (specialized) |
| slurry concentration: | Not recommended for slurry applications; maximum particle size < 25 μm if unavoidable |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It stores pressurized hydraulic fluid during low tension periods and releases it when tension drops, maintaining constant cable tension without continuous pump operation.
Nominal volume ranges from 0.5 to 50 liters, and maximum operating pressure is 1.0 to 1.6 MPa. Precharge pressure is typically 0.6 to 1.0 MPa.
The shell is typically made of 35CrMo alloy steel, and the bladder is NBR synthetic rubber. Carbon steel and stainless steel are also listed as materials.
Determine the required oil volume for tension maintenance, maximum operating pressure, and precharge pressure based on system demands. Verify all parameters with the manufacturer.
