The 4 1/2 inch outlet on the front is called the steamer outlet in the firefighting world. It goes back to the days when they actually used steam powered engines to pump water. I am a retired water supply operator and also a retired volunteer fire fighter. Your description of the hydrant is pretty much spot on.
The side discharges are not used for connecting hoses for firefighting directly, just for connecting alternative or additional supply lines. Firefighters always use a pumper for exact regulation of pressure and flow. The side discharges are also used by other members of the local municipality, for instance: flushing sewer lines and filling flush/vac trucks and street cleaning equipment.
I have a very nice old Mueller I found in a antique store.. I wish I could tell you the year it was made but no date on it... When I was restoring it I had to replace the two small nozzles because they were both odd sizes and not two and a half inches but more like two and a quarter inch 🤔 Couldn't figure out why that was but I removed those nozzles and replaced them with a standard two and a half inch size! Had a hard time finding one's that would work but I'm pretty resorsful . This hydrant only has the name of Mueller, Chatta.Tenn., and 41/4"... As I mentioned,no date...
Once a fire truck wants to refuel the water tank from a fire hydrant, does the process only rely on difference in pressure? And does the LPM stay fixed or it varies over time?
I am not an expert at all, but from what I gather, Yes they can refill on water pressure alone, or they can use the pump to suck from the line to fill the tank faster! They can even in an emergency suck from a pool or a lake to fill the tank.
Albydam- that's pretty cool! Used them to powerwash sidewalks at our condo but never knew the actual inner workings.

Thank you very much!
That fire hydrant was made at Mueller in Albertville, AL.! Been by there many times!

Looks like a banjo connection
