•Thetwo-ball design provides better priming of the lower foot valve.

Thedouble acting feature is standard in all ARO industrial pumps,

materialis delivered to the pump discharge outlet on both the upand

downstroke.

MAINTENANCE

Theair / hydraulic motor is completely separate from the lower pump end.

Thishelps to keep the motor from being contaminated by the material being

pumped.Periodically, flush entire pump system with a solvent that is com-

patible with the material being pumped.

Keepsolvent cup filled with this compatible solvent. This will keep mate-

rialfrom drying on the piston rod, which would drag thru t he packings,

ruinthem and eventually scour the piston rod.

Providea clean work surface to protect sensitive internal moving parts

fromcontamination from dirt and foreign matter during disassembly and

reassembly.

Beforereassembling, 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.
