The variety and versatility of the piston type design allows it to be utilized in over 90% of all potential applications.
From a volume of a few cubic inches to hundreds of gallons, and up to 20,000 PSI MAWP, the piston type hydro pneumatic accumulator can meet the diverse needs of many industries with a standard or custom design. Tobul piston type accumulators from 2″ to 24″ in diameter with fluid capacities from 4 cubic inches to 300 gallons and oeprating pressures up to 20,000 PSIG.
In the realm of fluid power systems, the piston accumulator and piston hydraulic accumulator represent pinnacle components for energy storage, pulsation dampening, and shock absorption. These devices leverage the mechanical principle of a piston to separate the compressed gas from the hydraulic fluid, ensuring a seamless transfer of energy. Designed for severe duty applications, piston accumulators provided by SCI are unparalleled reliability and efficiency in managing hydraulic system pressures. Their technical sophistication makes them indispensable in various industries, including aerospace, manufacturing, and heavy machinery, where system performance and safety are paramount. By enhancing system responsiveness and stability, piston accumulators play a critical role in optimizing operational outcomes. Partner with SCI to get yours!
