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)
