Externally Serviceable Air Distribution System (ESADS+):

Unique to SANDPIPER, the Externally Serviceable Air Distribution System (ESADS+) allows fast and simple access to both the pilot and spool valves—keeping downtime to an absolute minimum. All SANDPIPER AODD pumps are equipped with this patented technology, making in-line maintenance possible in under five minutes—perfect for remote or high-demand sites.

• On-Off-On Reliability Guaranteed
  Regardless of pilot valve position, the cross-drilled pressure ports in the air valve spool ensure consistent pneumatic bias. This boosts and maintains pilot pressure until the exact point of shift—eliminating spool drift caused by vibration or pressure imbalance.

• Fast, In-Field Maintenance
  With just four bolts removed, you can slide off the air valve assembly to access the patented cross-drilled pilot shuttle—home to the two O-rings most commonly requiring replacement. No need to remove the pump from service.
