Some pumps can see higher pressure when not operating.

You need to fully describe the application if you want meaningfull input.
At the moment the only answer to your question is - "sufficient to overcome failure in operation".
It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
RE: Maximum Operating and Inlet Pressure of a Pump
Max inlet pressure is what the pump designer needs to design the outer bit (the casing) and what class of inlet flange you need.
If there is a risk of back pressure through the pump with the inlet valves closed, then often the max inlet pressure can be the same as the max outlet pressure.
all depends on your system design and operation design.
