ASHUN Piston Accumulators are essential components in fluid power systems, capable of efficiently storing hydraulic energy, absorbing pulsations, and dampening shocks. Manufactured with high-quality materials and internationally certified, these accumulators ensure stable and reliable performance in various industrial applications.
Highlights
- Finely machined internal surface to reduce piston movement friction.
- End caps effectively prevent gas leakage and air moisture ingress.
- High-precision piston acts as a separator for gas and hydraulic oil.
- Sealing system prevents metal-to-metal contact between piston and cylinder wall, suitable for low temperature applications.
- Ideal for both heavy and light applications.
- Excellent extrusion resistance.
- Preferred option for media separation, such as fluid and gas.
- High cost performance.
- High durability

Technical Features
- Stores fluid energy in hydraulic systems for emergency use.
- Absorbs pulsations, reducing noise.
- Dampens shock pressure, acting as a shock absorber.
- Allows for miniaturization of pumps, reduces hydraulic fluid temperature, and saves energy.
- Compensates for leakage and temperature changes to maintain constant system pressure.
- Acts as a gas spring to absorb shocks between wheels and vehicle body.
- Substitutes for a hydraulic pump by intermittently transferring fluid with a piston-operated bladder.
- Reduces shock waves caused by rapid valve opening and closing.
- D260 series features excellent dynamic sealing performance, maintaining low friction operation.
