Pump Material  
1 - 400 series stainless steel  
2 - 300 series stainless steel  
The two-ball design provides better priming of the lower foot  
valve. The double acting feature is standard in all ARO indus-  
trial pumps. Material is delivered to the pump discharge outlet  
on both the up and down stroke.  
Packing Material  
C - UHMW-PE (upper and lower)  
K - Carbon and Graphite filled PTFE with nitrile ener-  
gizer (upper and lower)  
MAINTENANCE  
L - Mineral filled PTFE (upper and lower)  
P - UHMW-PE / Mineral filled PTFE staggered (upper)  
UHMW-PE (lower)  
R - Mineral filled PTFE / UHMW-PE staggered (upper)  
Mineral filled PTFE (lower)  
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  
the material from drying on the piston rod, which would drag  
through 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 matter during dis-  
assembly and reassembly.  
Before reassembling, lubricate parts as required. When assembling  
“O” rings, or parts adjacent to “O” rings, exercise care to prevent  
damage to “Orings and “Oring groove surface.

repeated several times to assure small enough diameter has  
been achieved to insure proper assembly.  
15. Apply lubricant to inside of (9) tube and carefully slide (9) tube  
over the (72) wiper and (71) “W” packing or (76) packing set,  
and onto (6) outlet body. NOTE: Once the (9) tube has cleared  
the packings, a rubber mallet may be used to drive (9) tube  
into place.  
16. Apply Loctite nickel anti-sieze to threads of (10) connecting  
rods and assemble three (10) connecting rods to (15) inlet  
body.  
17. Assemble (15) inlet body and components to (9) tube, aligning  
three (10) connecting rods with holes in (6) outlet body.  
18. Assemble three (12) nuts to (10) connecting rods, securing  
assembly. NOTE: Tighten (12) nuts to 60 - 70 ft lbs (81.3 - 94.9  
Nm). NOTE: Draw (12) nuts equally together and then tighten.  
TROUBLE SHOOTING  
see view A  
No material at outlet (pump continually cycles).  
Check material supply. Disconnect or shut off the air supply  
and replenish the material. Reconnect.  
Material on one stroke only (fast downstroke).  
The (21) lower ball may not be seating in the (22) ball 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 dam-  
aged, replace.  
Material on one stroke only (fast upstroke).  
The (27) ball may not be seating in the (28) ball seat (see lower  
pump disassembly). Remove (27) ball from (28) ball seat, clean  
and inspect. If the (27) ball is damaged, replace. Check for worn  
or damaged packings and seals. Replace the packings and seals  
as necessary.  
Material leakage out of the solvent cup or material appears 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.
