Q:
What new technologies are influencing hydraulic pump design?
43 answers
Answers:
High pressure water jet cutting and deep bore hole mining. I think robotics are using more and more as the number of procedures they are using perhaps. Auto body welding machinery. underwater welding submersibles. Lots of advancements in multiple categories.
~Scott H, Project Manager, Kelso, WA
Higher flows and pressures needed to run bigger equipment. Also more hyd are being used on farm equipment.
