Product information
High-Pressure Bellows Accumulator
Metal Bellows Gas-Liquid Barrier
Reduced Permeability vs Rubber Components
Very-Low-Permeation Application Context
SCHWERLL high-pressure metal bellows accumulator using a metal bellows as the gas-liquid barrier. Manufacturer product information describes reduced inherent permeability compared with rubber components and suitability for very-low-permeation applications. Model-specific ratings and technical documentation require configuration confirmation.
High-Pressure Metal Bellows Accumulator
SCHWERLL’s manufacturer product information identifies this product as a high-pressure bellows accumulator and states that it uses a metal bellows as the gas-liquid barrier.
Compared with rubber separation elements, the manufacturer states that the metal-bellows construction reduces the inherent permeability associated with rubber components and is suitable for applications requiring extremely low permeation.
The currently available product-specific evidence does not establish the supplied model’s numeric pressure rating, nominal volume, bellows or shell material, manufacturing method, operating temperature, fluid compatibility, precharge specification, leak-test performance, fatigue life or conformity documentation.
These parameters must be confirmed for the selected configuration.
SKU: SCH-1011
Frequently Asked Questions
What is a SCHWERLL high-pressure metal bellows accumulator?
SCHWERLL manufacturer product information identifies this product as a high-pressure bellows accumulator and states that it uses a metal bellows as the gas-liquid barrier.
How does the metal bellows affect gas permeation?
SCHWERLL manufacturer product information states that the metal-bellows construction reduces the inherent permeability associated with rubber components and is suitable for applications requiring extremely low permeation. This does not establish zero gas permeation or a specific helium leak rate.
Which technical specifications must be confirmed for the selected accumulator?
Confirm the manufacturer model, pressure rating, nominal volume, bellows and shell materials, manufacturing method, fluid and precharge requirements, operating temperature, interfaces, leak and fatigue test requirements, and applicable conformity documentation for the selected configuration.
Configuration review
Provide these parameters for configuration review: required working/design pressure, required nominal/usable volume, precharge requirement, fluid, temperature, connection/interface, installation envelope, required leak/permeation performance, cycle/duty requirements, and documentation/certification requirements.
Contact SCHWERLL to review the selected configuration.
