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,
fl ush entire pump system with a solvent that is compatible
with the material being pumped.
Keep solvent cup fi 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 mat-
ter during disassembly and reassembly.
Before reassembling, lubricate parts as required. When as-
sembling “O” rings, or parts adjacent to “O” rings, exercise
care to prevent damage to “O” rings and “O” ring groove sur-
face.
