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.

An arbor press with a big lever and ratchet is very quick to use, while a hydraulic press gives much higher pressure but is extremely slow.

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 ...

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 ...

Pressure transients in hydraulic systems are usually caused by valve operations that then create pump ripple and water-hammer effects.

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.
