Maximize your system's energy efficiency and safeguard your heavy machinery with the THM TS KA & KAA Series Piston Accumulators. Engineered to store massive quantities of hydraulic energy in a highly compact, hydropneumatic form, these accumulators utilize a precision-machined, sliding rigid piston to seamlessly separate the nitrogen gas charge from your operational fluid. Capable of handling extreme working pressures up to 375 bar and offering a massive volume range from a nimble 0.5 liters up to a colossal 500 liters, the KA & KAA Series provides unparalleled fluid power storage. By drastically reducing the required pump size and installed electrical power, these piston accumulators deliver the high-flow leakage compensation, severe shock absorption, and instantaneous response times required to dominate the heavy civil, road construction, and industrial manufacturing sectors.

Core Technical Specifications

• Component Architecture: Hydropneumatic Piston Accumulator
• Model Series: THM TS KA & KAA
• Operating Pressure Ratings: 250 Bar & 375 Bar configurations
• Volume Capacity Range: 0.5 Litres up to 500 Litres
• Operating Principle: Sliding rigid piston separating nitrogen gas and hydraulic liquid

Key Features & Engineering Advantages

• Superior Piston Architecture: Unlike traditional bladder designs, the rigid piston allows for an exceptionally high compression ratio and virtually eliminates gas permeation into the fluid. This ensures a significantly longer service life and the ability to safely process extremely high oil flow rates.
• Ultimate System Optimization: By storing high-pressure fluid during low-demand cycles and releasing it instantly during peak demand, these accumulators allow engineers to drastically downsize their main hydraulic pumps and electrical motors, boosting overall energy efficiency.
• Advanced Monitoring & Mounting: The rigid piston design allows for precise electronic monitoring of both pressure and physical piston position. Furthermore, unlike bladder accumulators, the KA & KAA Series can be safely mounted horizontally without risking seal damage, maximizing your spatial design freedom.
• Fail-Safe Reliability: Engineered for maximum job site safety. In the rare event of a seal failure, gas loss is gradual rather than catastrophic, and the rigid design allows for the total, 100% discharge of stored fluid when required.
• Customizable Scalability: Available with a wide array of specialized sealing solutions to accommodate extreme temperatures, corrosive fluids, and high-speed cycling. The external dimensions (diameter and length) can be optimized to perfectly match your specific manifold and chassis constraints.

Ideal Industry Applications:-

The massive 500-liter capacity, horizontal mounting capability, and high flow rates make the KA & KAA Series the ultimate energy storage solution for:
