Piston accumulator with crimped end cap design - ACP Series - (Europe) ACP04AA032R2K

Piston Accumulator designed for Mobile applications up to 30 litres, 100mm bore and 275 bar. The ACP piston accumulator offers long, reliable service life and due to its compact & cost effective design it is ideally suited for the mobile market.

The ACP piston accumulators incorporate a patented crimped design that provides high-strength coupling of caps to steel tube plus superior fatigue life. High grade carbon steel tube and end cap material allows heat to dissipate effectively and is micro-finished for extended seal life. The ACP series is a good alternative to a diaphragm accumulator as it is can provide enhanced nitrogen gas retention and has a compact and lightweight design.

Although these accumulators are offered in standard capacities, the steel shell design affords an easy way to "custom" manufacture an accumulator to meet the exact capacity for any customer application.

ACP piston accumulators are available in two versions; Rechargeable or Tamperproof. Rechargeable models allow the user to monitor and regulate the gas pre-charge to suit different operating conditions. Tamperproof, sealed-for-life versions of the ACP are pre-charged on assembly to customer specification and are completely maintenance free.

Parker Olaer have developed very sophisticated simulation software to optimize sizing recommendations for hydraulic accumulators. You can download the accumulator sizing software from the Product Support tab.

Markets:
• Mobile
• Construction Equipment
• Material Handling Equipment
• Renewable Energy
• Agricultural Machinery

Features/Benefits:
• The ACP piston accumulator is manufactured to EU Pressure Equipment Directive 2014/68/EU – and can be used in any European Union or EEA country without additional certification.
• The high-strength crimped construction provides long, reliable service life and its small piston seal area minimizes permeability. The piston design also prevents sudden accumulator failure.
• The ACP piston accumulator is available in a wide range of lengths and bore sizes and allows installation to be adapted to available space. Custom sizes are available for unique applications. Rechargeable and ‘tamperproof’ versions are available with (for customer charging) or without the gas valve.
• A wide range of port types and sizes are available. SAE straight thread are fitted as standard. BSPP is a standard option.
• The lightweight piston design allows fast response to reduce shock in rapid cycling applications.
• Parker’s piston accumulators are compatible with a wide variety of fluids. Standard accumulators (with nitrile seals) may be used with petroleum-based industrial oils or water-based flame resistant fluids. Optional seals compatible with most industrial fluids are available with temperature ranges from -40°C to 160°C.
• High burst test safety factor.

Applications:
• Fork lifts and cherry pickers
• Transportation vehicles
• Construction and Mining
• Turbine Engines
• Machine Tools
• Hydrostatic Drives
• Assembly Automation
• Renewable Energy (Wind and Solar)

Function:
Hydraulic accumulators are an essential component for the optimum operation of a hydraulic circuit. The accumulator enables:
• Energy Storage: Saves energy without loss and redistributes when required therefore reducing installed power.
• Pressure Compensation: Absorbs pressure spikes from pumps or other components to control pressure and flow rates in the hydraulic circuit.
• Volume Control: Absorbs fluid volume variations induced by temperature changes in a closed hydraulic circuit and maintains a rated pressure.
• Emergency Energy Storage: In case of failure of the main energy source, these accumulators can provide sufficient energy to complete an operation or to realize a full hydraulic cycle.
• Hydraulic Spring/Shock Absorber: A piston accumulator can act as a gas spring suppressing shocks and vibrations in hydraulic systems of lifting vehicles (e.g. Forklift trucks) and maintains real suspension of the load on a gas spring.
