Externally Serviceable Air Distribution System
All Sandpiper pumps feature this exclusive ESADS+ technology that allows for quick and easy replacement of air valve and pilot valve components without removing the pump from the line. This technology offers quick remote site serviceability in under five minutes by simply removing only 4 bolts as compared to the standard maintenance process that takes up to an hour to dismantle the piece completely. This system includes patented cross-drilled pressure ports to eliminate spool drifting due to vibrations and / or unbalanced pressure or system conditions. Users can get easy access to the patented, cross-drilled pilot shuttle containing the two O-rings that most commonly fail on any AODD (air-operated double diaphragm) pump with continuous usage.
