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.

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,
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.

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.

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.

Material on one stroke only (fast upstroke).

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

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.
