The two-ball design provides better 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.  
TROUBLE SHOOTING  
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  
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 downstroke).  
The (21) lower ball may not be seating in the (22) seat (see  
lower pump disassembly). Remove the ball from the seat,  
clean and inspect the ball and seat area. If the ball or seat  
is damaged, replace.  
y
Material on one stroke only (fast upstroke).  
Check for worn or damaged packings and seals. Replace  
the packings and seals 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.
