PPO Series Liquid Pumps

Oil or Oil/Water Service

PPO pumps are lightweight and rugged making them ideal for portable power packs and are available in eight pressure ratios as listed below. PPO pumps are single acting, single air drive head types.
Anodized aluminum bodies and plungers on the PPO4-PPO12, cast iron bodies on the PPO22-PPO189. Tool steel plungers and polyurethane seals on all.
All PPO series pumps are standard with bottom inlet. For a side inlet, add – S to the catalog number.
Maximum air drive pressure is 145 psi. PPO pumps require less drive pressure because the pump is driven in both directions with no spring under the piston.
This design reduces noise and provides less chance of cavitation.
Minimum air drive pressure 15 psi.
For air control option … add – ACM to catalog number.
