Heavy Duty Hydraulic Accumulators

Accumulators play a central role in the heavy-duty segment and ensure consistent performance and safety, whether on long highway stretches, in tough construction site use, or in the field under changing loads.
Corteco hydraulic accumulators keep machines moving: efficiently, safely, and durably. They store energy during periods of low load and release it again at peak loads, for example when lifting heavy components or when controlling several hydraulic functions simultaneously. This reduces pressure fluctuations in the system, extends the service life of cylinders, valves, and lines, and minimizes downtime.

They enable the controlled lowering of loads or the safe shutdown of machines. At the same time, they absorb sudden pressure surges, such as those that occur when hydraulic movements are stopped abruptly. This protects the entire system, whether in long-distance transport, on construction sites, or in agricultural applications.
With Corteco, you get original Freudenberg quality: developed and tested according to strict original equipment standards and optimized for the most demanding heavy-duty applications.
