Press pump, need help.

[JTknives]

I am thinking of building a full size press and found a place where i can get this pump for supper cheep. i know it's designed to run with very large motors but could i use it with say a 10hp or so. it just looks like a really nice pump

I'm guessing from the charts that it will take a 20HP motor to deliver 16GPM at 2000PSI. If using it on a constant speed unit, at 5-6 GPM, then a 10HP motor should be fine.
I'm not sure what this pump is made for, but a simple 16GPM two-stage pump should only cost about $80-$120 new.
