8.3 Maximum operating pressure
The diagram shows the maximum operating pressure based on unit model and temperature of
pumped liquid.
Figure 19: Temperature-pressure diagram
P1max + Pmax ≤ Maximum operating pressure (PN)
NOTE: The formula applies to units with motor with axially locked bearing on the drive side
(standard Xylem).
