It is the responsibility of the employer to place this information in the hands of the operator. Keep for future reference.

Use only genuine ARO® replacement parts to assure com-
patible pressure rating and longest service life.

ends.

FOR ADDITIONAL SAFETY PRECAUTIONS AND IMPOR-
TANT INFORMATION.
This manual only covers the lower pump section. It is one 
of four documents which support an ARO pump. Replace-
ment copies of these forms are available upon request.

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.

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, 
fl ush entire pump system with a solvent that is compatible 
with the material being pumped.
Keep solvent cup fi lled 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.

Check material supply. Disconnect or shut off  the air sup-
ply and replenish the material, reconnect.

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.

Check for worn or damaged packings and seals. Replace 
the packings and seals as necessary.

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.
