- Operation: Manual and/or solenoid-operated discharge
- Optional with proximity switch or mechanical limit switch
Key Benefits
The compact combination of components simplifies accumulator connection to the hydraulic system and provides multiple safety and operational advantages.
- Minimum of space and maintenance and installation required. As all the individual units are combined in one block, considerably fewer pipe fittings are necessary for installation.
- Considerable reduction in installation time
- Multiple connections options available – imperial, metric, manifold mounted and weld nipple to suit various accumulator designs.

Safe & Controlled Pre-Charging
The regulator reduces incoming pressure during the pre-charging phase of the accumulator, ensuring a controlled and safe charging process. This prevents potential damage to system components caused by excessive pressure.
Connection Options
Multiple connection types are available — imperial, metric, manifold-mounted, and weld-nipple — to suit different accumulator designs and installation requirements.
This block enables continuous monitoring of pre-charge levels in hydraulic accumulators, ensuring they maintain the recommended pre-charge pressure over extended periods. There is port available to facilitate pre-charge top-up
Safety Devices for Accumulators
Gas Safety Valve
A spring-loaded relief valve designed for gas-side pressures up to 350 bar. When the set pressure is exceeded, the valve opens automatically and recloses after pressure drops by a maximum of 10% below the set point.
Bursting Disc Plugs
Bursting discs protect pressure equipment from excessive gas-side pressure. If system pressure exceeds the rated burst value, the internal membrane ruptures, releasing nitrogen safely and preventing catastrophic failure.
Temperature Fuse
It offers thermal protection, activating when temperatures exceed safe limits, preventing potential hazards due to overheating.
These indicators offer real-time monitoring of piston positions within the accumulator, aiding in assessing operational status and facilitating maintenance by providing accurate positional information and operational control. These type includes proximity / limit switch, linear transducers, ultrasonic sensor or mechanical indicating rods available for identifying piston location.
Accumulators must be mounted and supported using external supports such as clamps or brackets. Proper mounting ensures safety, stability, and reduced vibration in hydraulic systems.
Steel Brackets
Brackets are made of steel and are screwed onto a wall or frame to absorb weight. These open-design brackets are mounted on the oil port side of bladder or piston accumulators, providing reliable support.
C-Type Clamps
C-type clamps, available in one-piece or two-piece construction with a central screw, are the most popular choice. They are usually fitted with rubber inserts to minimize mechanical vibration. Standard material is galvanized steel, with stainless steel available on request.
U-Bolt Clamps
U-bolt clamps with plastic pipe saddles are commonly used for piston accumulators. For nitrogen bottles and pressure vessels, they are supplied without the plastic saddle. The saddle reduces vibration and ensures proper grip and mounting.
Its recommended to use a single clamp, when the accumulator length is less than twice its diameter. For greater lengths, we recommend using two or more clamps or one clamp and one bracket with support ring.
Nitrogen Charging Kits
Nitrogen charging kits are vital accessories for hydraulic systems, used to safely and accurately charge accumulators with nitrogen gas. They ensure the correct pre-charge pressure, which is critical for maintaining accumulator efficiency and optimizing hydraulic circuit performance. Each kit includes all necessary components for charging and monitoring nitrogen levels, making them an essential tool for system maintenance and safety.
Hydac Nitrogen Charging Kit
Specifically engineered for Hydac accumulators, this kit provides precise control over the nitrogen charging process. It is tailored to the requirements of Hydac systems, ensuring correct pre-charge pressure and consistent performance. A reliable choice for professionals who need dependable charging equipment for Hydac hydraulic systems.
N2 Charging Kit
The N2 Charging Kit is designed for hydraulic systems that use nitrogen to maintain pressure in accumulators. It allows safe and efficient charging, ensuring proper pressure levels for optimal accumulator operation. With all components included, it supports accurate charging and helps maintain the safety and reliability of hydraulic circuits.
We also provide the below-mentioned types of Accumulators and related accessories designed to ensure safe operation, proper mounting, and effective handling of the Accumulators, including nitrogen charging kit, Hydac nitrogen charging kit, and N2 charging kit.
