Hydraulic accumulator accessories
As pressure equipment, hydraulic dampers are subject to mandatory labelling and strict safety regulations. HYDAC hydraulic accumulator accessories ensure that your installation is not only technically efficient but also legally secure. From fluid-side protection from excess pressure to mounting in line with the applicable industrial standards and machinery regulations, we supply all the components that you need for initial start-up and long-term operation. High-quality accessories significantly reduce the risk of leakage and mechanical load at the line connections.

Maximum service life for hydraulic accumulators
Using HYDAC charging and testing equipment such as the FPU series, technicians can precisely monitor the nitrogen pre-charge pressure (also known as the nitrogen pre-fill). This is essential, because every accumulator – regardless of its design – will only perform optimally at the correct pre-charge pressure. Regular testing prevents damage to the separating element, such as the accumulator bladder or diaphragm, and protects piston accumulators from the piston forcefully striking the oil-side or gas-side piston accumulator end cap. While the FPU series provides the ideal tools for regularly inspecting individual accumulators, our high-performance nitrogen charging stations (N2 servers) minimise downtimes when dealing with large volumes. They are specifically designed for charging entire accumulator stations and accumulators with downstream nitrogen cylinders, where large volumes of gas need to be transferred swiftly and safely. Investment in high-quality accessories pays for itself rapidly through the prevention of component failures and extension of service intervals.
Modular expansion and straightforward selection
A perfect fit, without compromise: All the accessories can be seamlessly integrated thanks to our modular system logic. We not only supply the optimum mounting solution, but also guarantee the standard-compliant protection in line with the relevant national regulations. Benefit from our expert advice and receive the perfect protection for both the gas side and the system side, supplied directly from the factory.
