This manual covers the lower pump section. It is one of four

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 filled with this compatible solvent. This will
keep the material from drying on the plunger, which would drag
through the packings, ruin them and eventually scour the plunger.
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 “O” rings and “O” ring groove surface.
