• Thetwo-ball 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

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 lubri­cant that is compatible with the material being pumped.
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.
