Hydraulic Accumulators: Industry Applications

Our accumulators deliver reliable energy storage, shock absorption, and pulsation damping for critical applications across diverse industries.

Agricultural & Heavy-Duty Machinery

For tractors, combines, and construction equipment, reliable hydraulics are essential. Our accumulators absorb shocks from terrain and implements, while also smoothing pump pulsation. Supported by our CDZ charging vehicles and AQF/SAF valve blocks, they ensure peak performance and safety in demanding conditions.

Wind Power Systems

Our piston accumulators provide the essential energy reserve required for fail-safe operation in wind turbine pitch control and braking systems.

Marine & Offshore

Our corrosion-resistant accumulators ensure dependable performance for steering and stabilizer systems in the challenging marine environment.

Steel & Heavy Industry

In high-shock environments like steel mills, our robust accumulators and custom stations protect equipment by absorbing energy surges and maintaining system stability.
