High-Pressure Industrial Bladder Accumulator

Q: What is the maximum pressure rating and operating temperature range of a Schwerll high-parameter bladder accumulator?

Schwerll high-parameter bladder accumulators are pressure-rated up to 207 MPa (30,000 psi) with an operating temperature range of -40°C to +120°C, depending on bladder elastomer selection. The bladder is pre-charged with nitrogen to 90% of minimum system pressure to ensure optimal response and provide a maintenance-free lifespan exceeding 1 million cycles.

Q: How does Schwerll ensure compliance with ISO, CE, and ASME standards for custom bladder accumulators, and what is the typical delivery time for OEM orders?

Every Schwerll accumulator is designed, manufactured, and pressure-tested in-house per ISO 9001:2015 quality management, while standard models carry CE (PED 2014/68/EU) and ASME Section VIII Div. 1 certifications. Custom sizing calculations use your required flow, pressure ripple, and pre-charge specifications to guarantee performance. Typical OEM delivery is 4–8 weeks after engineering drawings approval, with expedited options available for standard sizes.
