Product category: Specialized products / Accumulator bladder and diaphragm / Diaphragm for low-permeability diaphragm accumulators
Internal SKU: SCH-1024. Manufacturer part number and exact host fitment require confirmation.
SCHWERLL publishes this product as a low-permeability diaphragm component for welded diaphragm accumulators. It is a component used within the accumulator assembly, not a complete accumulator pressure vessel. The manufacturer publishes a long-term OEM / matching-component context; exact host fitment and interchangeability require confirmation.
The official product page states that the described diaphragm is manufactured in France and references virgin-rubber material, simulation-based geometry, compression/expansion design, specialized adhesive and integral-molding manufacturing processes.
SCHWERLL also describes the diaphragm qualitatively in terms of low permeability, stable compression behavior and stable oil-drain deformation. The available evidence does not publish numeric permeability, gas-loss, cycle-life or service-life performance data. Multiple rubber materials are described qualitatively, without a supplied-component compound and media compatibility matrix.
The official product page lists a 0.1β4 L diaphragm specification range. The available English and Chinese sources do not define the exact engineering quantity represented by this range, so it must not be interpreted as a verified fluid capacity, gas capacity or host-accumulator nominal volume without technical clarification.
The product page references NF ISO37 / ISO37 material testing. This is a manufacturer-published material test-method statement, not a component certification or published test result. Exact edition, compound, specimen, batch, laboratory and test result are not identified. Exact host fitment, manufacturer part number, diaphragm geometry, rubber compound, media compatibility, temperature range and compliance documentation must be confirmed for the supplied component.
The published specification range is explained in the product text. Its engineering meaning remains unresolved and it is not a verified component capacity.
Official English product description Β· Official Chinese product description
It is a diaphragm component intended for welded diaphragm accumulators. The available official product evidence describes the diaphragm component, not a complete accumulator assembly or universal replacement for all diaphragm accumulators.
SCHWERLL's official product page lists a 0.1β4 L diaphragm specification range. The English source refers to diaphragm capacities while the Chinese source refers to diaphragm specifications, but neither defines the exact engineering quantity. The range must therefore not be interpreted as a verified diaphragm fluid volume, gas volume or accumulator vessel capacity without technical clarification.
No standalone Post58 diaphragm pressure rating is established by the available evidence. The current 250 bar and 350 bar values originate from complete diaphragm-accumulator family context and must not be represented as an independent pressure rating of the diaphragm component.
SCHWERLL's official product page states that the described diaphragm is manufactured in France and references virgin-rubber material, simulation-based geometry, specialized adhesive and integral-molding processes, together with qualitative low-permeability and stable-deformation characteristics. Exact rubber compound, fluid compatibility and temperature range require configuration confirmation.
The official product page references NF ISO37 / ISO37 in the diaphragm material-testing context. This is a material test-method statement, not a product certification. The available evidence does not provide the exact edition, compound, specimen, batch, laboratory or test result. CE/PED/ASME component certification and the exact SCH-1024 manufacturer part number have also not been established by the available evidence.
Please provide the following customer inputs for fitment and material review. These inputs do not establish universal fitment, cross-brand interchangeability, custom-size availability or component ratings.
