GENERAL DESCRIPTION
WARNING DO NOT EXCEED MAXIMUM OPERATING PRESSURE AS INDICATED ON PUMP MODEL PLATE. 
WARNING REFER TO GENERAL INFORMATION SHEET FOR ADDITIONAL SAFETY PRECAUTIONS AND IMPORTANT INFORMATION.
yThis manual only covers the lower pump section. It is one of four documents which support an ARO pump. Replacement copies of these forms are available upon request.

General Information - Air / Hydraulically Operated Piston Pumps
:Lower Pump End Operator’s Manual
Air / Hydraulic Motor Operator’s Manual
yThe 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, flush the entire pump system with a solvent that is compatible with the material being pumped.
Keep the solvent cup filled with this compatible solvent. This will keep the material from drying on the piston rod, which could 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 disassembly and reassembly.
Before reassembly, lubricate parts as required. When assembling “O” rings or parts adjacent to “O” rings, exercise care to prevent damage to “O” rings and “O” ring groove surface.

LOWER PUMP REASSEMBLY
All threads are right hand.
Apply lubricant to all rubber parts before assembling (it is not necessary to lubricate UHMW-PE and PTFE packings).
NOTE: All threads are to be cleaned before reassembly. The cleaning of threads is a benefit to help insure the overall reassembly process. Please note the use of the following materials: Loctite® Primer T™ with Loctite 242® Threadlocker and Loctite Nickel Anti-Seize.
All threaded parts are stainless steel and care should be taken on threaded connections.
Apply Loctite Nickel Anti-Seize to threads as indicated (figure 1, page 3) during assembly.
Apply ARO Wet-Sol "Plus" to threads as indicated (figure 1, page 3) during assembly.
Apply Primer T with Loctite 242 Threadlocker to threads as indicated (figure 1, page 3) during assembly. Follow these instructions to apply materials to threads.
a.Clean parts with solvent and allow to dry.
b.Apply Primer T to mating threaded parts and allow 3 to 5 minutes to dry at 72° F.
c.Apply Loctite 242 Threadlocker to mating threaded parts being assembled.
d.Assemble parts within 3 minutes of applying Threadlocker.
e.Tighten per "Torque Requirements", (see page 3).
f.Curing times: Fixed in 5 minutes and full cure in 2 hours. NOTE: If Primer T is not used, the cure time will be effected as follows: fixed in 20 minutes and full cure in 24 hours.
