Bladder Accumulators
Installation
All accumulators shipped from the factory will be
precharged to a nominal pressure in order to seat the
poppet valve on the hydraulic port. In this case the
precharge will not be listed on the label. However, in
some cases they will be shipped with a nitrogen
charge, the value of which will be marked on the label/
nameplate.
Keep the hydraulic port covered to keep out foreign
material until ready to make the hydraulic connec-
tions.
The accumulator should be mounted within 25° of
vertical with the hydraulic port on the bottom. It should
also be rigidly mounted using appropriate mounting
hardware, which is shown in
the Accumulator Accessories section of this catalog.
The hydraulic circuit, which contains a connection to
the accumulator, should be designed so that it auto-
matically discharges all hydraulic fluid from the
accumulator when the equipment is turned off.

Maintenance InstructionsBladder Accumulators
Pre-Charging
Use only an inert gas such as nitrogen for precharging piston
accumulators. Do not use oxygen or shop air.
If water pumped nitrogen is not available, oil-pumped nitrogen
may be used. (C.G.A.Standards: Nitrogen gas bottles for water
pumped nitrogen has a right-hand valve thread which requires
charging and gauging assembly †144595XX00 for units up to
3000 psi. Oil-pumped nitrogen requires a left-handed valve thread
(use †144596XX00).
It is recommended to use charging and gauging assembly as
shown in Figure 1 (Part †144595XX00, right-hand thread;Part
†144596XX00, left-hand thread), and in Figure 4 Part
†0871XX0000 for 1-15 gallon & Part †087102XX00 for 10-150 cu.
in.accumulator rated for 3,000 psi or less.For accumulators rated
for 5,000 psi, as well as the 25-40 gallon, 3,000 psi accumulators,
use assembly shown in Figure 6 (Part †144912XX00).If other
equipment is used, make sure it is compatible with the gas valve
assembly and nitrogen source.All components must be rated for a
pressure at least as high as the nitrogen source.
It is strongly
recommended that the nitrogen bottle used have a high
pressure regulator.
Make sure nitrogen supply is shut off. Attach hose to nitrogen
bottle.If accumulator has a gas valve as shown in Figure 8A or
8B, follow steps A through L and skip steps F and J.If accumula-
tor has a gas valve as shown in Figure 9, follow steps A through L
and skip steps E and I.
Accumulators having gas valve per Figure 8Aor8B
(A) Remove gas valve guard and gas valve cap.
(B) Back gas chuck “T” handle all the way out (counterclockwise)
before attaching charging assembly to accumulator gas valve.
(C) Close bleed valve.
(D) Making sure not to loop or twist the hose, attach swivel nut to
gas valve and tighten (10-15 in.lb.) (11.5-17cm kg).
NOTE: For top repairable units having valves as shown in Figure
8B, a valve extension as shown in Figure 3 must be attached
to the gas valve after removing valve cap.
(E) Turn gas chuck “T”handle until the gauge starts showing the
pressure in the accumulator. Do not turn the “T”handle all the
way down, as it will damage the valve core.
(F)
For gas valves as shown in Figure 9, hold gas valve at point
“C”with one (1) wrench while unscrewing hexnut at point “D”
with a second wrench. This will open the poppet inside the
gas valve. Note:Three (3) turns will fully open the valve.
(G)Crack open nitrogen bottle or regulator valve and
slowly fill
accumulator. Caution:If the precharge is not done slowly, the
bladder may suffer permanent damage. Shut off when gauge
indicates 100 psi above desired precharge. (Note:It is
recommended that precharge pressure be at least 25%of
maximum system pressure.) Damage to bladder may occur if
this ratio is not maintained or exceeded. For shock suppres-
sion applications, precharge is usually set at about 65%of
system pressure. When the accumulator is used to supple-
ment pump flow, auxiliary power supply or leakage compensa-
tion, precharge is usually set at approximately 90%of
minimum system pressure.
(H) Let the precharge set for 10 to 15 minutes. This will allow the
gas temperature to stabilize. If the desired precharge is
exceeded, close nitrogen bottle valve, then slowly open bleed
valve. Do not reduce precharge by depressing valve core with
a foreign object. High pressure may rupture rubber valve seat.

Maintenance
Little maintenance is required for a bladder accumulator.If there is
external leakage, tighten all connections.If leakage continues, remove
accumulator from system and replace faulty components.
After original installation, check pre-charge once during first week to
see that no leak has developed.Thereafter, check pre-charge monthly.
Check pre-charge if the system is acting sluggish.If pre-charge is low,
check gas valve for leakage and recharge.
If there is no gas in bladder and fluid appears at gas valve, unit must
be removed and bladder replaced.
Pre-charge Checking Procedure
Using appropriate valve in the hydraulic system, discharge all oil from
accumulator.
For accumulators rated for 3000 psi, either use gaging assembly in
Figure 2 (Part #085122XX00) or gaging assembly in Figure 5 (Part
#087101XX00) and follow Steps 1 through 7.

Bottom Repairable
Accumulators
Figure 1. Once the
accumulator has been
removed from the equipment,
the accumulator body should
be secured in a vise, prefer-
ably a chain vise.If a standard
jaw vise is used, brass inserts
should be used to protect the
accumulator hydraulic port
assembly from damage.Clamp
on wrench flats only when
using a jaw vise to prevent
accumulator from turning.
Figure 2.Remove bleeder
plug (if the accumulator is
equipped with one) on
hydraulic port assembly. Using
a spanner wrench, remove
lock nut from the hydraulic port
assembly;use an adjustable
wrench on the flats located on
the port assembly to prevent
port assembly from rotating.
Figure 3. Remove spacer,
then push the hydraulic port
assembly into the shell prior to
Step 4.
Figure 4. Insert hand into the
accumulator shell and remove
the o-ring backup, o-ring,
metal
backup. Seperate the anti-
extrusion ring from the
hydraulic port. Fold anti-
extrusion ring to enable
removal of anti-extrusion ring
from shell.

port plug from accumulator
shell.
Figure 6.Remove jam nut
from bladder valve stem.
Secure valve stem from
twisting with an appropriate
wrench applied to the valve
stem flats.
Figure 7.Fold bladder and pull
out of accumulator shell.A
slight twisting motion while
pulling on the bladder reduces
effort required to remove
bladder from shell.If bladder is
slippery, hold with a cloth.
Clean &Inspect
Cleaning:All metal parts
should be cleaned with a
cleaning agent. Seals and
soft parts should be wiped clean.
Bladder:Inflate bladder to normal size.Wash bladder with
a soap solution. If soap solution bubbles, discard bladder. After
testing, deflate bladder immediately.
Disassemblyof Conventional
Top-Repairable Accumulators
The conventional top-
repairable accumulator
uses a gas-end adapter
which is retained in the
shell with an anti-extrusion
ring exactly like those
used in port assemblies
(see Figure 10).
1. Make sure the gas
is relieved from the
accumulator.
(See Removal of
Accumulator from System).
2. Remove jam nut from bladder gas valve stem using a
1-5/16"socket wrench.
Hydraulic Port:Inspect assembly for damage; check the
poppet plunger to see that it spins freely and functions properly.
In cases where the accumulator is used with water, check
assembly for rust and/or defective plating. If rust is detected,
clean with commercial rust remover. If parts are pitted, replace
with new components.If protective plating is damaged, replace
with new components.
Seals:Check anti-extrusion ring and soft seals for damage and
wear; replace all worn or damaged seals with original equip-
ment seals from the Hydraulic Accumulator Division.
Shell:After shell has been cleaned with a cleansing agent,
check the inside and outside of shell.Special attention should
be given to the area where the gas valve and hydraulic assem-
bly pass through the shell.Any nicks or damages in this area
could destroy the accumulator bladder or damge new seals.If
this area is pitted consult factory.
Bladder Assemblyin Bottom Repairable
Accumulators
1. After shell has been cleaned and inspected, replace
accumulator shell in vise or on table.
2. Spray the inside of the accumulator shell with approximately
10%of the accumulator volume with clean system fluid to
lubricate and cushion bladder. Make sure the entire internal
of the shell is lubricated.
3. With all gas completely
exhausted from bladder,
collapse bladder and fold
longitudinally in a compact
roll.
4. Figure 8.Insert the bladder
pull rod through the valve
stem opening and through
the shell fluid port; attach
the bladder pull rod to the
bladder valve stem.
5. With one hand, pull the
bladder pull rod while
feeding the bladder into the
shell with the other hand.
Slight twisting of bladder will
assist in this insertion.

bly and tighten securely.This will squeeze the o-ring into
position.Use appropriate wrench on flats of port assembly
to insure the unit does not turn.
10. Thread bleeder plug into the hydraulic port assembly.
11. Position accumulator so that fluid (same fluid as used in the
system) can be poured into the accumulator (add approx-
imately 10%of the accumulator capacity).This fluid will act
as a cushion when the accumulator is pre-charged with
gas.
12. Pre-charge accumulator to desired pressure. See pre-
charge instructions. Install accumulator on machine.
