HYDAC standard bladder accumulators consist of the pressure vessel, the flexible bladder with gas valve and the hydraulic connection with check valve. The pressure vessels are seamless and manufactured from high tensile steel.
Bladder accumulatorSB330N
The flow-optimised design of the standard oil valve enables the maximum possible operating fluid flow rate to increase to 25 l/s on this accumulator type.
High flow bladder accumulatorSB330H
HYDAC high flow bladder accumulators, type SB330H, are high performance accumulators with a flow rate of up to30 l/s. The fluid port is enlarged to allow higher flow rates.
Working temperature and operating fluid
The permitted working temperature of a bladder accumulator is dependent on the application limits of the metal materials and the bladder. Outside this temperature range, special materials must be used. The operating fluid must also be taken into account. The following table displays a selection of elastomer materials with temperature range and a rough overview of resistant and non-resistant fluids, on a case-by-case basis, information must be requested regarding the resistance and the resistance must be tested specifically
