The 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.
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,
fl ush the entire pump system with a solvent that is compat-
ible with the material being pumped.
Keep the solvent cup fi lled 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 mat-
ter during disassembly and reassembly.
Before reassembly, lubricate parts as required. When assem-
bling “O” rings or parts adjacent to “O” rings, exercise care to
prevent damage to “O” rings and “O” ring groove surface.
