ated Pumps.

Air or Hydraulic Motor Operator’s Manual.  
The chop-check design provides for easy 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  
Figure 1  
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 matter during dis-  
assembly and reassembly.
