What's UL Listed Pressure?
What's UL Listed Pressure?
(OP)
I'm looking over a fire pump catalog. There is a column that e.g. for a 300 gpm fire pump shows "87-139" UL Listed Pressure (PSI).
Do you know what is 87-139?
Hereunder is the link for the datasheet:

The particular fire pump model can be purchased at any pressure between 87 and 139 psi.
