Certified Energy Storage for High-Pressure Systems #
ASHUN piston accumulators are built for high-pressure hydraulic systems, providing energy storage and pulsation absorption. They combine sealing technology with EU PED certification and are used in heavy machinery and automated production lines to reduce maintenance costs and stabilize system pressure.
Official category page: Piston Accumulators
Design Features #
- Top-tier safety certification — All products are certified under EU PED 2014/68/EU (Module H1) for operation in high-pressure environments.
- Advanced sealing and low maintenance — A precision sealing system minimizes gas permeation and wear, balancing performance with low maintenance.
- High-pressure tolerance and pulsation absorption — Designed for pressure peaks, absorbing fluid pulsation to stabilize pipeline pressure and protect downstream components.
- Flexible customization and compact design — Multiple volumes and configurations in a compact body with unrestricted mounting angles.
- Long service life versus bladder accumulators — The piston design avoids bladder aging and rupture, offers a broader compression ratio and provides smoother, linear gas pressure output.
