OUR SIGNATURE EN
SURES YOUR SUCCESS
Even in the most severe applicati
ons and environments, the Sandpiper Signature Series™ of AODD pumps are engineered to provide industry leading durability and performance.
ON-OFF-ON Reliability Guaranteed
One of the most prominent features of any SANDPIPER pump is the exclusive ESADS+Plus Air Distribution System that allow
s for quick remote site serviceability. Independent of the pilot valve position, the cross-drilled pressure ports in the main directional air valve spool provide a pneumatic bias of the spool at either end of travel. This is accomplished by directing (inner) chamber pressure to the end of the spool, boosting and sustaining pilot pressure until point-of-shift of the pilot valve. The benefit of this is that it eliminates spool from drifting due to vibration and/or unbalanced pressure or system conditions.
