High Pressure Piston accumulator with crimped end cap design - HCP Series - (Europe) HCP15EA500E2KRD

The HCP piston accumulator offers the highest pressure rating of 35O bar for a crimped piston accumulator and is the best in class in terms of weight per litre. Applications include industrial, renewable energy and mobile.

The HCP 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 HCP 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.

HCP 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 HCP 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.

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.

Note: Maximum Flow Rate (lpm) based on 120 in/sec maximum piston speed, port & fitting size will become limiting factors for most applications.
