Stauff® 1.4L Diaphragm Accumulator 210 Bar – STDA-140
The Stauff® STDA-140-NBR-P3-B-M-N-1 is a high-capacity 1.4L diaphragm accumulator engineered for robust energy storage and pressure stabilisation. Rated for a maximum working pressure of 210 bar, this genuine Stauff® unit effectively dampens hydraulic shocks and pulsations to safeguard industrial and mobile hydraulic circuits.
Designed for long-term reliability, this Type STDA configuration features a durable NBR (Buna-N®) diaphragm and a tamper-proof, non-repairable construction. We provide Australia-wide shipping for this unit. To ensure safe transit and maintain compliance with dangerous goods regulations, this accumulator is supplied with no gas pre-charge.
Product Benefits & Performance
- High-Volume Stabilisation: Ideal for larger hydraulic systems requiring significant pulsation dampening and energy storage.
- Shock Absorption: Protects system integrity by mitigating hydraulic "water hammer" and reducing mechanical vibration.
- Maintenance-Free Design: The sealed, non-repairable (STDA) construction provides a durable, safety-focused solution for demanding environments.
- Nationwide Dispatch: Shipped uncharged to facilitate fast delivery across Australia without dangerous goods restrictions.
