Other Products from HYDAC’s Accumulator Line
Diaphragm Accumulators
Diaphragm accumulators are frequently used where small volumes are
required, light weight is important, a higher pressure ratio is required
(up to
10:1) , and low cost is a prime factor. Two styles are available weld (non-
repairable) and threaded (repairable) . Both are suited for energy storage and
shock applications.
Nominal volume: 5 in
3
to 1 gal.
Max. working pressure: 3000, 4700, and up to 10,000 psi
Flow rate: up to 40 gpm
Piston Accumulators
A wide range of piston accumulators is available. Piston position monitoring is
available using proximity switches, extending piston rod or ultrasonic
techniques. Auxiliary gas bottles are frequently used with piston accumulators
to provide the required gas volume.
Nominal volume: 1 qt. to 100 gal.
Max. working pressure: 3000, 5000, and up to 15000 psi
Flow Rate: up to 2000 gpm
Charging & Gauging
To maintain system performance, HYDAC recommends a regular check of the
gas precharge pressure. A loss in the gas precharge pressure will cause a
drop in the system efficiency and could cause damage to the bladder,
diaphragm or piston accumulator. By means of a charging and gauging unit,
hydro-pneumatics accumulators are precharged with dry nitrogen or their
existing gas precharge pressure is checked. For these purposes, a charging
and gauging unit is connected to a commercially available nitrogen bottle via
a flexible hose. The charging and gauging units incorporate a gauge, check
valve in the charging connection, manual bleed valve and T-handle.

Bladder Accumulators
The bladder style accumulator is a great general purpose accumulator. It has
a wide range of sizes for energy storage requirements and is well suited for
shock applications.
Nominal volume: 1 qt. to 15 gal.
Max. working pressure: 3000, 5000 and up to 15000 psi
Flow rate: up to 480 gpm
