This question is of no practical significance. The user does not care about this figure. The concern should be the nominal diameter, which is fitted with flanges and pipes. Moreover, the pump shell is cast iron, the inside diameter is not processed, and there is no matching parts, there is only one manufacturing size.

If it is a centrifugal pump, the nominal diameter of the outlet is less than 4 inches, there is a conical short tube to enlarge the standard 4 inch outlet flange, from here, is the standard 4 inch flange connection.
