Can't identify a pump

[Ed Love]

I have a BorgWarner hyd pump with S15S4AH71L stamped in the aluminum housing. The inlet and outlets are 3/4" pipe thread. Does anyone know the specs of this pump?
Thanks, Ed

I have read that you can calculate the pump because I had a hydraulic motor that I meaured. As I remember you measure the gear x the width and then the RPM will give the volume. There might be something else but if you find the correct site you will be close.

J.J. thanks for the info. I've looked at the site and it appears it's intended to calculate HP of a pump or HP needed in a motor based on known info. i.e. flow, pressure. These are the things I don't know.
Thanks, Ed
