Recycling & Disposal Bladder Accumulators
Recycling & Disposal
Prior to recycling, the accumulator must be made
inoperable by drilling through its cylindrical shell.
Once inoperable, the accumulator can be recycled by
separating the steel parts from the rubber seals and
bladder. Recycle rubber and steel parts separately.
Bladder Accumulators can contain residual hydraulic
fluid. The hydraulic fluid can be hazardous to the
environment. Dispose of the bladder-type accumulator
in accordance with the provisions applicable in your
country. Dispose of any hydraulic fluid residues
according to the respective safety data sheets valid
for these hydraulic fluids.
