Diaphragm Accumulators

Welded diaphragm accumulators SBO

This accumulator features a dual-chamber design with a flexible diaphragm that separates the gas and fluid sections. As system pressure rises, fluid enters the accumulator and compresses the gas; when pressure drops, the gas expands, forcing the stored fluid back into the circuit. It includes a welded pressure vessel that can be sealed or gas-rechargeable, multiple fluid connection options, and an integrated valve poppet at the base of the diaphragm.

HYDAC Diaphragm Accumulators Threaded SBO

The HYDAC Threaded SBO Diaphragm Accumulators feature a rugged, forged construction with an exchangeable diaphragm that separates gas and fluid for efficient energy storage and release. Designed for durability, they include corrosion protection options like plastic coating, galvanic or chemical treatments, and stainless steel versions for use with aggressive fluids.
