AIR AND LUBE REQUIREMENTS  
WARNING EXCESSIVE AIR PRESSURE. Can cause pump  
damage, personal injury or property damage.  
MAINTENANCE  
S A filter capable of filtering out particles larger than 50 microns  
should be used on the air supply. In most applications there is no  
lubrication required other than the "O"ring lubricant which is apĆ  
plied during assembly or repair.  
Refer to the part list pg. 4 for Service Kit Information, parts view on  
pg. 5. and Repair Proceedures on pgs 6 and 7.  
S Certain ARO ``Smart Parts" are indicated which should be availĆ  
S The pump can be rotated 360_to suit the application. It may be  
mounted upside down or on the wall with no effect on suction lift or  
operating efficiency. The filter and regulator need to be oriented in  
a normal vertical direction to function properly.  
able for fast repair and reduction of down time.  
S Provide a clean work surface to protect sensitive internal moving  
parts from contamination from dirt and foreign matter during serĆ  
vice disassembly and reassembly.  
S Pipe plugs included for the material inlets, they can be switched to  
accommodate piping requirements however the fluid inlet must alĆ  
ways be in the port closest to the mounting base.  
S Keep good records of service activity and include pump in prevenĆ  
tive maintenance program.  
S When lubricated air is necessary, supply the air lubricator with a  
good grade of SAE 90 wt. non-detergent oil and set the lubricator  
to arate not to exceed one drop per minute.

factorypre-assembledreplacementairvalvesection.  
4. Install the shaped gasket into the minor valve block and push the  
major valve block into the minor valve block, retain with screws and  
torque to 6 in.lbs.  
PUMP DISASSEMBLY:  
1. Place the pump on a flat workbench. Remove both cover plates  
and set them aside.  
NOTE: Do not lubricate the gasket or valve block surfaces.  
5. Insert new, lubricated ``U''cups in each of the air caps. The lips of  
the ``U''cups should face towards the diaphragm chambers. Install  
the air cap seal.  
6. Pre-assemble each of the two diaphragms by first inserting the diĆ  
aphragm nut through the new diaphragms, Appy Loctite #242 to  
the threads, attach the backup washer, secure with the a 9/16"  
wrench and spanner wrench. Using a torque wrench, tighten the  
diaphragm nut and washer to 80-inch pounds.  
2. Using a7/16-inch wrench, loosen the bolts that run through the  
pump and remove the six nuts. Pull the bolts through the pump  
body and set them aside.  
3. The fluid caps and manifolds may fall free at this time. If not, grasp  
the fluid caps and separate them from the pump body.  
4. The air inlet fluid cap has two small ``O"rings at the air inlet and exĆ  
haust ports. Remove these with the ``O"ring pick.  
5. The manifold tubes may have pulled free of the pump when the  
fluid caps were removed, if not remove both tubes from the pump  
body.  
NOTE: Be careful not to round off the diaphragm nut. Backup  
``O"rings are included in the Service Kit for models with PTFE diaĆ  
phragms.  
6. Remove the ``O"rings from the ends of each manifold tube.  
7. If the manifolds did not fall free, separate them from the fluid caps  
at this time.  
For the 637274-X and 637273-XXX Service Kits:  
8. To remove the checks, it may be necessary to push a dowel  
through the fluid caps.  
9. Use the pick to remove any ``O"rings that remain in the manifold or  
fluid cap.  
10. With the 9/16" socket and 9/16" wrench, loosen and remove either  
diaphragm nut. Gently pull the diaphragm away from the pump  
body.  
7. Install new, lubricated ``O"rings onto the four complete check asĆ  
semblies that are included with the Service Kit. Also put new  
``O"rings on each end of the two manifold tubes.  
PUMP REASSEMBLY:  
8. First hand tighten the connecting rod to one of the diaphragm asĆ  
semblies.  
9. Place the air cap on end. Insert the air valve assembly and bushing  
in place. (be sure the U-cups are installed). Align logo plates and  
push the air caps together.  
NOTE: Be sure the bushing, and air valve assembly remain in  
place.  
10. Lubricate the connecting rod and insert it into the air cap.

REASSEMBLY (CONTD)  
17. Press two of the check assemblies into the lower inlet ports of the  
fluid caps. The checks are keyed and can be assembled only one  
way.  
NOTE: If the old checks are to be used, clean all parts in an apĆ  
propriate solvent.  
18. Place manifolds over each check, pushing firmly to secure the  
check and the manifold tube.  
11. Attach the second diaphragm assembly to the connecting rod,  
hand tighten the (pre-assembled) diaphragm nut and washer until  
it bottoms out on the connecting rod.  
NOTE: Models with Teflon diaphragms have backup ``O"rings that  
are placed in the groove of each air cap. Do not over-tighten the  
nut.  
19. Press the remaining checks into the upper, outlet ports of the fluid  
caps. Make sure the smaller seat opening is inserted first.  
20. Place manifolds over each check, pushing firmly to secure the  
check and the manifold tube.  
21. Insert two bolts through each manifold. Secure by attaching a nut  
to each bolt. Applying a small amount of anti-seize compound or  
lubricant to the threads will help prevent the nut from binding.  
22. Tightening sequence for the long bolts:  
12. Replace the ``O"rings at the air inlet and exhaust ports of the air inĆ  
let fluid cap.  
13. Properly align the fluid cap and attach it to the pump body. When in  
place, the air inlet should be at the upper right, with the exhaust at  
the lower left.  
14. Insert a bolt into the bore just below the air inlet and one just above  
the exhaust port. Applying a small amount of anti-seize compound  
or lubricant to the threads will help prevent the nut from binding.  
Properly align the second fluid cap and push it into position.  
15. Secure the fluid caps by installing nuts onto each bolts, but do not  
tighten fully at this time.  
IMPORTANT ASSEMBLY NOTE: The fastener nuts have ribs  
which lock into the material, for best results place a socket wrench
