Closed-Type Tank Buffer

Reservoir buffer for stabilizing pressure fluctuations in sealed return-oil tanks used in closed-loop hydraulic systems.

Closed-Type Tank Buffer

Schwerll Industrial Fluid Power Equipment - Closed Type Tank Buffer

Product category: Specialized products / Closed oil tank buffer device

Internal SKU: SCH-1020

SCHWERLL’s Closed-Type Tank Buffer is used in closed-loop hydraulic systems where a sealed return-oil reservoir can experience pressure fluctuations associated with entrained air. The buffer is used to help stabilize the closed hydraulic system.

SCHWERLL’s official product page publishes a design pressure of 10 bar and an approximate maximum working pressure of 2 bar for this product entry. These values are page-level published data and must not be interpreted as confirmed SCH-1020 supplied-model ratings without approved configuration documentation.

The official page also lists 10, 20, 25, 32, 42 and 50 L options, but the available source does not define the exact volume quantity represented. The supplied size, allowable operating pressure, materials, media compatibility and documentation requirements must therefore be confirmed for the actual offered configuration.

Official Published Technical Context

Published page-level data — confirm supplied configuration.

  • Official page design pressure: 10 bar.
  • Official page approximate maximum working pressure: approximately 2 bar.

These are distinct page-level published quantities, not confirmed SCH-1020 supplied-model ratings. Exact applicability and allowable operating pressure require approved configuration documentation.

Frequently Asked Questions

What is the SCHWERLL Closed-Type Tank Buffer used for?

SCHWERLL's official product page describes the Closed-Type Tank Buffer for closed-loop hydraulic systems in which a sealed return-oil reservoir can experience pressure fluctuations associated with entrained air. The buffer is used to help stabilize operation of the closed system.

What pressure values are published for the Closed-Type Tank Buffer?

The official SCHWERLL product page publishes a design pressure of 10 bar and an approximate maximum working pressure of 2 bar. These are page-level published values and are not treated as confirmed SCH-1020 supplied-model ratings without approved configuration documentation.

What size or volume options are published?

The official product page lists 10, 20, 25, 32, 42 and 50 L options. The available source does not define the exact volume quantity represented, so the supplied size and engineering meaning of the published volume must be confirmed before selection.

Are CE, PED, ASME, proof-test or accumulator-sizing claims established for SCH-1020?

The available Post50-specific evidence does not establish CE/PED/ASME product certification, a guaranteed 1.5×PN proof-test program, 3.1 material certificate coverage, or accumulator ΔV/P0/P1/P2 sizing for SCH-1020. Required ratings, testing and documentation must be confirmed for the actual supplied configuration.
