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 ...

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.
