Joe OZ thats correct. There are 2 main types of WJ pumps. Intensifier and Direct Drive (piston). We have One company I know of uses a servo driven intensifier which we are actually considering going to but most are hydraulic driven. One issue with the hydraulics is waste heat generated maintaining pressure while not cutting. There are many issues with home brew WJ we have not yet unpacked in this discussion but one at a time lets do it.
