Freudenberg Sealing Technologies Bladder Accumulators are designed for industrial and commercial fluid power applications by making use of the relative compressibility of an inter gas versus a fluid, and are one of the most commonly used components in industrial and commercial fluid power systems worldwide. They are utilized for a wide variety of applications, including : energy storage, shock or pulsation dampening, leakage compensation, thermal expansion, energy conservation/supplement pump flows, noise reduction, and improved fluid system response times.
Our Bladder Accumulators are constructed of high strength seamless chrome moly carbon steel shell, with high grade elastomeric bladders, with are assembled in accordance with ASME pressure vessel standard. Available in a variety of industry standard capacities and pressures, the bladder type excels at absorbing system shocks and pulsations, especially those of high frequency/low modulation.
Widely used and accepted in global industry, the bladder type is available with variety of optional port connections and anticorrosive coating, both externally and internally. Due to the internal membrane, the bladder-type accumulator is highly resistant to fluid contaminants, and can be assembled to function in lower temperature environments if necessary.
Bottom repairable models (TBR Series Accumulators)
Bottom repairable bladder-type design TBR are the most commonly found units in the marketplace. Fluid capacities are generally limited to small variety of sizes (one quart to fifteen gallon/approximately 1 liter to 57 liters. Pressure rating of these vessels are generally 3000 PSI (207Bar), 5000 PSI (345 Bar) or less. Specially rated units, though, can contain up to 6600 PSI (455 Bar).
GENERAL DESIGN DATA Maximum Working Pressure 3,000 PSI (207 Bar) Maximum Proof Pressure 4,500 PSI (310 Bar) Operating Temperature (Buna/Nitrile) -20° to +200°F (-28° to 93°C)
