Maximum Inlet Pressure
The following table shows the maximum permissible inlet
pressure. However, the actual inlet pressure + pressure
against a closed valve must always be lower than the
maximum permissible operating pressure.
(Refer to pressure/temperature curves on page 13 to verify
MAWP of pump)
