In some hydraulic systems, intensifiers or "boosters" replace pumps or compressors. They are most often used when one form of fluid energy is available, but a specific system must use another form.

A hydraulic ram is a clever device invented over 200 years ago that can pump water uphill with no other external source of power except for the water flowing into it and there is a way to take ...

Ronald Knecht explains how a disciplined maintenance regime for Water Glycol (HFC) hydraulic fluids can help keep systems operating more effectively and efficiently—and for longer.

Hydraulic systems are powerful tools, but you don't always need complex machinery to create one. With basic materials and a bit of creativity, it's possible to craft a mini hydraulic pump that works ...

The downside is that the vacuum pump oil gets contaminated with water vapor, but that’s far easier and cheaper to replace that a couple hundred gallons of hydraulic oil.
