*May vary depending on configuration. Suction lift diminishes over time. Recommended installation level less than 3 ft above source.
**dB Level at 60 psi 50CPM (top) and 60 psi maximum CPM (bottom). Sound Levels measured in accordance with ISO9614-2:1997.
***Dry-run capable PSASD030 and PSASD060 pumps require flooded suction and may have a reduced warranty unless prior arrangements are made with White Knight. Contact White Knight for details.
