HYDAC Hydraulic Accumulators with Back-Up Nitrogen Bottles
HYDAC nitrogen bottles are a cost-effective solution for increasing gas volume in hydraulic systems, allowing smaller accumulators to be used without sacrificing performance. Available in various designs, they support both bladder and piston accumulators, optimizing space, reducing costs, and ensuring reliable energy storage.
Spare parts and accessories available on request.
The HYDAC Accumulator Charging and Testing Units (FPU-1 series) are essential tools for charging hydraulic accumulators with nitrogen and monitoring or adjusting pre-charge pressure. Suitable for bladder, piston, and diaphragm accumulators, each unit includes a valve body, spindle, check and release valves, pressure gauge, charging hose, and A3 adapter. High-pressure variants—FPS 600, FPK 600, and FPH 800—support pre-charge pressures up to 800 bar, providing reliable performance across a wide range of accumulator types and applications.
Special high pressure models are also available:
Accumulator charging valves DLHSD / DLHSR for manifold or inline mounting
The HYDAC Accumulator Charging Valves DLHSD (manifold) and DLHSR (inline) offer reliable recharging of accumulators up to 350 bar, with minimal leakage and built-in check valves for easy installation. Compact and efficient, they feature adjustable switch-off pressures and low pressure drop, ensuring full accumulator capacity and seamless integration into hydraulic systems.
Charging and testing blocks F+P are used to charge and test back-up type hydraulic accumulators
The HYDAC Charging and Testing Block F+P (DN16/DN32, up to 400 bar) is designed for charging and testing back-up type hydraulic accumulators. With ports for FPU-1 units and pressure gauges, it offers optimized dimensions, optional integration of a GSV6 gas safety valve, and shut-off capability for nitrogen bottles ensuring safe, efficient system operation.
Nitrogen Charging Units N2-Server
The HYDAC N2-Server Nitrogen Charging Units (mobile, portable, and stationary versions) enable fast, cost-effective charging of all HYDAC accumulator types up to 350 bar. Designed for efficient use of nitrogen bottles down to 20 bar residual pressure, they ensure quick filling or topping up of pre-charge pressure in bladder, diaphragm, and piston accumulators.
HYDAC Accumulator Safety Elements provide reliable gas-side protection against excessive pressure or temperature in hydraulic accumulators. These include burst disks, temperature fuses, and gas safety valves—all CE marked and supplied with a declaration of conformity. A gas safety block simplifies installation and operation by offering connection ports for the safety devices.
