* Values for the maximum connuous inlet pressure taken using a RV12 backing pump at sea level in
negligible magnec eld. Values for the maximum connuous backing pressure taken under no ow
condions at sea level in negligible magnec eld. Refer to Vent opons, vent valve connecon and
control on page 57 for cooling condions. At pressures above these, the rotaonal speed decreases
below nominal.
