GENERAL DESCRIPTION
FLUID SECTION DISASSEMBLY
1. Remove (107) reducing bushing.
2. Remove six (26) screws, releasing two (4) flanges and (11) “O”
rings.
3. Remove eight (27) screws and (29) nuts, releasing (15) fluid cap.
4. Secure (14) screw in a vise, with (101) air valve body upward.
5. Using a 15/16” socket on (186) screw, unthread and remove
(186) screw and (10) washer.
6. Remove (68) air cap from (7) diaphragm and components.
7. Remove (14) screw from the vise. Unthread and remove (1) rod,
releasing (2) stopper, (5) back-up washer, (196) cushion, (7) or (7
and 8) diaphragms, (6) washer, (3) “O” ring and (9) washer from
(14) screw.
8. Remove four (131) screws, releasing (101) air valve body from
the (68) air cap.
The ARO® shock blocker pulsation dampener is designed to work
with 1:1 ratio pumps having an outlet pressure not exceeding 120
p.s.i. (8.3 bar). The shock blocker will effectively reduce material
pressure variations, surges and shock to piping and delivery in fluid
systems during pump reversal. It can significantly contribute to
pulse reduction in low pressure spray applications.
Accurate selection of wetted material will assure longest service life
and minimize down time. Several material options are available for
the body and diaphragm materials. Fluid section materials avail-
able include: aluminum, cast iron and stainless steel. For specific
fluid compatibility, consult the chemical manufacturer.
The shock blocker uses a single air pressurized, flexible diaphragm
working against the fluid line pressure. Several diaphragm material
options are available to allow custom matching to the fluid mate-
rial for best compatibility (refer to the model description chart).
Shock blocker units can also be added in series to provide addi-
tional dampening on the material.
9. Remove (144) “U”cup from (68) air cap.
10. Remove (103) sleeve from (101) air valve body.
Pressure relief through the exhaust port is a normal compensating
function of the control valve in the shock blocker. It will automati-
cally adjust itself to the required operating pressure once the mate-
rial pressure has been applied. The pressure supplied to the shock
blocker needs to be equal to the material pressure to provide the
proper dampening effect.
FLUID SECTION REASSEMBLY
Clean and inspect all parts. Replace worn or damaged parts
with new parts as required. Lubricate all replacement parts and
metallic moving parts with Lubriplate® FML-2 grease upon re-
assembly.
y
1. Grease and assemble two (172) “O”rings to (103) sleeve.
2. Assemble (103) sleeve into the (101) air valve body.
3. Grease and assemble (70 and 173) “O” rings to (101) air valve
body.
AIR AND LUBE REQUIREMENTS
EXCESSIVE AIR PRESSURE. Can cause pulsation
WARNING
dampener damage, personal injury or property damage.
A filter capable of filtering out particles larger than 50 microns
should be used on the air supply. There is no lubrication re-
quired other than the “O” ring lubricant which is applied during
assembly or repair.
If lubricated air is present, make sure that it is compatible with
the “O”rings and seals in the air motor section of the pump.
4. Grease and assemble (144) “U”cup into (68) air cap.
5. Assemble (101) air valve body to (68) air cap.
6. Assemble four (131) screws, securing (68) air cap. NOTE: Tighten
(131) screws to 20 - 30 ft lbs (27.1 - 40.7 Nm).
7. Assemble (9) washer, (3) “O” ring, (6) washer, (7) or (7 and 8)
diaphragms, (196) cushion, (5) back-up washer and (2) stopper
to (14) screw. NOTE: For models with PTFE diaphragms: Item
(8) Santoprene diaphragm is installed with the side marked
“AIR SIDE” towards the pump center body. Install the PTFE dia-
phragm (7) with the side marked “FLUID SIDE” towards the (15)
fluid cap.
8. Assemble (1) rod to (14) screw.
9. Grease and assemble two (173) “O”rings to (1) rod.
10. Place this assembly into (68) air cap.
11. Assemble (10) washer and (186) screw into (101) air valve body
and thread into (1) rod. Clamp (14) screw in a vise, with (186)
screw upward, and tighten (186) screw to 65 - 70 ft lbs (88.1 -
94.9 Nm).
12. Remove assembly from the vise and assemble to (15) fluid cap,
securing with eight (27) screws and (29) nuts. NOTE: Tighten (27)
screws to 60 - 70 ft lbs (81.3 - 94.9 Nm).
y
y
OPERATION
DO NOT EXCEED 120 P.S.I. (8.3 BAR). Operating
CAUTION
at higher pressure can cause explosion, resulting in property
damage or severe injury.
Pressure relief through the exhaust port is a normal compen-
sating function of the control valve in the shock blocker. It will
automatically adjust itself to the required operating pressure
once the material pressure has been applied.
Operate the system for a few minutes to equalize air and fluid
chambers of the pulsation dampener.
y
y
PARTS AND SERVICE KITS
Refer to the part views and descriptions as provided on pages 4
and 5 for parts identification and Service Kit information.
13. Grease and assemble two (11) “O”rings to two (4) flanges.
14. Assemble two (4) flanges to (15) fluid cap, securing with six (26)
screws. NOTE: Tighten (26) screws to 60 - 70 ft lbs (81.3 - 94.9
Nm).
15. Apply Lubriplate FML-2 grease to threads of (101) air valve
body. Apply PTFE tape to threads of (107) reducing bushing
and assemble to (101) air valve body.
Certain ARO “Smart Parts” are indicated which should be avail-
able for fast repair and reduction of down time.
y
y
MAINTENANCE
Provide a clean work surface to protect sensitive internal mov-
ing parts from contamination from dirt and foreign matter dur-
ing service disassembly and reassembly.
Keep good records of service activity and include pump in pre-
ventive maintenance program.
Before disassembling, empty captured material in the fluid cap
by tipping the pulsation dampener on end.
