Parker Hannifin's new ABE range of bladder accumulators for Hydraulic
systems come in five optional compounds for use with all common hydraulic
fluids, and are claimed to be more tolerant of contamination compared
with other accumulator types. The shells are constructed from seamless
chrome-molybdenum alloy steel with forged ends, offering maximum
strength. The tolerance to contamination is enhanced by the absence of
dynamic sealing surfaces. With no static friction to overcome or piston
mass to accelerate, bladder accumulators offer fast response times,
retaining their high performance over a wide range of operating
conditions, including closed loop operation. A range of volumes is
available up to 48.5 litres and the maximum working pressure ranges from
210 to 420bar.
