got a job where i need a hand pump that wont quit on me. what’s the deal with the “two speed” on this Enerpac P77?

Question by: Warren M on Apr 6, 2026, 4:36 PM

Two speed means it has two operating speeds so you can move oil faster when there is little to no load, then switch to a slower stroke for better control when the work gets tougher. It’s meant to make the pumping more efficient on real hydraulic jobs instead of doing every stroke the same way.
