Proper RPM for PTO operation

(01-07-2019 )NoTime Wrote:  I would say around 150 at 1000 RPM. At 700 RPM the lines are just barely warm. Of course a lot depends on where I’m pumping off at but when I’m pumping off butane it’s a little hotter because I don’t have any pressure to help unload

Pick up a handheld laser temp gauge (they are cheap) check in several areas while your pumping. 150 degrees is fine even up to 170 degrees above that I would be worried, and I am only speaking from a hydraulic system understanding as I don't know if the heat transfers to the product? don't want you to blow up :-(
If you can off load at 1000 rpm's and hydraulic system is within acceptable perimeter then maybe your ok?
