*May vary by configuration or system. Suction lift diminishes over time. Recommended installation level less than 3 ft above source.
**dB Level at 100 psi 50 CPM (top) and 100 psi maximum CPM (bottom). Sound Levels measured in accordance with ISO9614-2:1997.
***Dry-run capable PXASD pumps require flooded suction and may have a reduced warranty. Contact White Knight for details.
