1. Reliable Hydraulic Pressure
The diaphragm provides a tight seal between the hydraulic fluid and nitrogen gas, preventing mixing and maintaining consistent pressure in the accumulator.
This reduces leakage and ensures stable breaker performance.
2. Durability in Tough Conditions
Made from high‑quality rubber/elastomer compounds, the diaphragm resists wear, oil exposure, high temperature, and repeated flexing — which is critical in heavy‑duty construction work.
3. Efficient Energy Storage & Release
It enables effective energy storage in the accumulator by compressing nitrogen gas when oil pressure rises and releasing it quickly during impact strokes, supporting strong and steady hammer blows.
