(REV. F)
WARNING
SURE AS INDICATED ON PUMP MODEL PLATE.
WARNING
ADDITIONAL SAFETY PRECAUTIONS AND IMPORTANT INFORMATION.
This manual 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.
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.
DO NOT EXCEED MAXIMUM OPERATING PRES-
REFER TO GENERAL INFORMATION SHEET FOR
650XXX-X Pump Model Operator’s Manual.
General Information for Air Operated or Hydraulically Oper-
ated Pumps.
Lower Pump End Operator’s Manual.
Air or Hydraulic Motor Operator’s Manual.
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 entire pump
system with a solvent that is compatible with the material being
pumped.
Keep solvent cup 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 matter during disassembly and reassembly.
Before reassembling, 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.
