The Bladder NXQ.A-25/31.5-L-EH is a low-pressure hydraulic accumulator component designed for use in turbine lube oil systems and emergency hydraulic circuits. It has a nominal volume of 25 litres and operates at a maximum pressure of 3.15 MPa, with an EH-grade hydraulic fluid rating. The unit includes a vulcanized rubber bladder, carbon steel shell, and integrated charging port compatible with ISO 4409. It is specifically engineered for space-constrained installations in power plant auxiliary systems.
The bladder is constructed from ethylene propylene diene monomer (EPDM) rubber, selected for its resistance to water-based hydraulic fluids and high-temperature stability up to 120°C. This differs from standard nitrile bladders used in oil-based systems. The housing is formed from seamless carbon steel with a 4 mm wall thickness, and the end caps are secured with threaded bolts. Typical industry tolerances for bladder expansion are ±2% of nominal volume under rated pressure.
This accumulator is primarily procured by maintenance teams at hydroelectric and nuclear facilities where water-based fluids are used to reduce fire risk. Orders are typically placed in quantities of 10 to 30 units per project. Packaging is in sealed plastic-lined wooden crates with desiccant. Trade terms are usually FOB Chengdu, with payment by irrevocable letter of credit or T/T against inspection report. Delivery lead time is not stated but commonly ranges from 6 to 10 weeks.

Before ordering, confirm the bladder material is EPDM and not nitrile, as this affects fluid compatibility. Verify the pre-charge pressure specification matches your system's operating curve. Request a dimensional drawing to ensure the mounting flange and port orientation align with your existing installation. This unit is not interchangeable with oil-based accumulators without system redesign.
Logistics are typically shipped FOB Chengdu. Lead time is unconfirmed but often 6 to 10 weeks due to custom packaging and lack of inventory. Payment terms are commonly L/C or T/T with inspection. Incoterms must be clearly defined. Buyers should require a packing list with unit serial numbers and test records to support traceability and warranty claims.
Upon delivery, inspect the bladder for surface cracks, discoloration, or swelling. Test the charging valve for air leaks using soapy water. Confirm the housing has no dents or corrosion. Retain original packaging until installation is complete. If the unit fails a pressure test, request replacement with documented test results. Do not install without verification of fluid compatibility.
