TROUBLE SHOOTING  
The chop-check design provides for easy priming of the  
lower foot valve. The double acting feature is standard  
in all ARO industrial pumps. Material is delivered to the  
pump discharge outlet on both the up and down stroke.  
No material at outlet (pump continually cycles).  
Check material supply. Disconnect or shut off the air sup-  
ply and replenish the material, reconnect.  
y
MAINTENANCE  
Material on one stroke only (fast downstroke).  
The (21) check may not be seating in the (22) seat (see  
lower pump disassembly). Remove the check from the  
seat, clean and inspect the check and seat area. If the  
check or seat is damaged, replace.  
y
The air / hydraulic motor is completely separate from the  
lower pump end. This helps to keep the motor from being  
contaminated by the material being pumped. Periodically,  
flush entire pump system with a solvent that is compatible  
with the material being pumped.  
Keep solvent cup filled with this compatible solvent. This will  
keep material from drying on the piston rod, which would  
drag thru the packings, ruin them and eventually scour the  
piston rod.  
Provide a clean work surface to protect sensitive internal  
moving parts from contamination from dirt and foreign mat-  
ter during disassembly and reassembly.  
Before reassembling, lubricate parts as required. When as-  
sembling “O” rings, or parts adjacent to “O” rings, exercise  
care to prevent damage to “O” rings and “O” ring groove sur-  
face.  
Material on one stroke only (fast upstroke).  
The (34) valve rod may not be seating in the (28) seat (see  
lower pump disassembly). Remove the valve rod from the  
seat, clean and inspect the valve rod and seat area. If the  
valve rod or seat is damaged, replace. Check for worn or  
damaged packings. Replace the packings as necessary.  
y
Material leakage out of the solvent cup or material ap-  
pears on the pump plunger rod.  
Relieve the pressure in the pump and tighten the solvent  
cup until leakage discontinues. If this procedure does not  
aid in stopping the leakage problem, the upper packings  
may be worn (see lower pump disassembly). Replace the  
packings as necessary.

fer facing down) and the other (23) “O” ring into the (15)  
pressure chamber body.  
10. Assemble the (26) plunger rod and components into the  
(15) pressure chamber body with the (30) primer rod go-  
ing in first. Slide the (25) check stop into place in the (25)  
pressure chamber body.  
11. Place the (7) gasket in the (25) check stop.  
12. Lubricate the middle packing assembly and the inside of  
the (9) suction tube and carefully slide the suction tube  
over the (26) plunger rod and middle packing assembly  
and into the (25) check stop.  
13. Install the three (10) tie rods.  
14. Place the (7) gasket on the end of the (9) suction tube.  
NOTE: Apply a small amount of grease on the gasket to  
help keep it in place.  
15. Assemble the (6) pump body over the (26) plunger rod  
and onto the (10) tie rods. Seat the (9) suction tube into  
the (6) pump body.  
16. Assemble the (43) wave spring, (53) male packing  
washer, (51 and 52) “V” packings and (115) backup onto  
the (26) plunger rod and into the (6) pump body (refer to  
page 3).  
17. Install the (1) solvent cup assembly and hand tighten.  
18. Push the (26) plunger rod down to expose the (30)  
primer rod at the bottom of the pump. Assemble the (31)

away from the pump) onto the (30) primer rod, securing  
with the (33) lock nut.  
19. Push up on the (30) primer rod until the primer rod is  
inside the (15) pressure chamber body, then tighten the  
(1) solvent cup assembly.
