Pump curve for older Peerless Fire Pump

[FFP1]

Does anyone know where I can find the manufacturer's pump curve for a 1,500 gpm @ 125 psi Peerless Model 6AF 15-B fire pump?

I am not sure about the manufacture date, but the pump is 20+ years old, has serial #313999 and the pump diameter is 17 in.

Call Peerless and give them the serial number they will send you the test curve from the bench test when new.
