The APL piston accumulators are new extremely durable series of accumulators by Hydro Leduc. The APL accumulators are used mainly for energy storage in hydraulic systems. They are distinguished by the ability to work in any position.

Nominal capacity: from 0.5 through 4 dm3; maximum allowable operating pressure: 250 bar

The APL accumulators have a cylindrical construction with an internal piston. A body of accumulator are designed with a high mechanical resistance forged steel body. Due to piston design, these accumulators are more durable than bladder and diaphragm accumulators. A set of seals ensures effective separation of gas and fluid and provides easy adaptation for different fluids and working temperatures.

In view of piston design of APL accumulators, they can be used in various applications almost without limit except to reach maximum pressure. It means these accumulators can be applied indynamic, slow and static work conditions. Moreover, they can be mounted in any positions.

Features:

• Capacity: 0.5 – 4 dm3;
• Maximum allowable operating pressure: 250 bar;
• Charging: with charging screw or charging valve;
• Operating temperature range: from -20 to +80°C (standard);
• Mineral-based hydraulic fluids (standard).

Advantages:

• High durability at high volumetric ratios;
• Possibility of total and rapid discharge of fluid;
• Assembly in any position;
• Minimal gas loss during use;
• Easy adaptation for high temperatures (+120°C);
• Easy adaptation for non-standard fluids.
