I am wanting to build a PTO pressure washer what RPM does this pump need to be turned in order work properly? Tractor is 65 HP and 540 PTO speed. I can get pulleys to raise or lower RPM but I don't want to overturn the pump. All ideas are welcome. Thanks

I have not experienced building a PTO driven pressure washer. However, the MAX pump speed is 1450 RPM. I have attached a spec sheet for you to view.
