why were hydraulic presses invented

Hydraulic presses use liquid pressure to produce enormous force, using Pascal's principle which states that an enclosed fluid maintains constant pressure. Joseph Bramah invented the first hydraulic press in 1795 - his revolutionary invention enabled greater industrial production.

Joseph also invented pick-proof locks and other devices he employed in his locksmithing business. An accomplished inventor, he also made numerous significant discoveries related to hydraulics.

Blaise Pascal

In 1648, French mathematician and physicist Blaise Pascal made an important discovery that would revolutionize hydraulic power. Pascal discovered that when force is applied to fluid in a closed system, pressure will remain uniform across its entirety - this principle became known as Pascal's Law and forms the cornerstone of all modern hydraulic systems.

Hydraulic presses are indispensable machines on factory floors, used for stamping, forming and pressing purposes. Joseph Bramah introduced the first hydraulic press back in 1795; today this press is often known as "The Bramah Press".

An essential hydraulic press works using two cylinders: master and slave. By exerting moderate mechanical force on either cylinder, they generate greater mechanical forces when compressed together; force created in one inch travel up the master cylinder will increase ninefold!

Joseph Bramah

Joseph Bramah, born 1748 and dying 1814, invented the first hydraulic press (also referred to as a Bramah Press). A hydraulic press uses liquid pressure to convert mechanical power. Bramah's invention stood out because he chose oil over water - which could become corrosive under high loads or evaporate completely - while also realizing its denser nature would allow more powerful hydraulic forces than would water could offer.

Bramah's concept drew upon the same principle discovered by Blaise Pascal: when pressure changes within a fluid that cannot be compressed, the force will spread throughout its system and lead to devices like hydraulic presses and other machines which use liquid pressure as their energy source.

Hydraulic presses feature fewer moving parts than other machines, which makes them safer and simpler to operate. They're also quieter - an essential feature when pressing sensitive materials such as KBr into pellets for FTIR spectroscopy analysis.


At home or at a steel mill, hydraulic presses are one of the backbones of industry. From stamping and forming processes to pressing applications, hydraulic presses play an essential role.

A four column hydraulic press  function similarly to any other hydraulic system: a master cylinder connected via pipes is connected to a slave cylinder with smaller dimensions and piston. Applying force to either of these cylinders causes fluid from them to flow back to be compressed by the master cylinder for greater force output.

Bramah invented his first hydraulic press in 1795 and started the industrial revolution by allowing manufacturers to automate machinery such as printing presses and cranes. He replaced water with oil due to its non-corrosive properties; higher loads can be handled more safely, and high pressure forces do not cause its evaporation resulting in quieter modern hydraulic presses than their predecessors.


Hydraulic presses have many uses across various industries. From sword making to creating fat-free cocoa powder, hydraulic presses provide immense amounts of force and pressure in their work. Furthermore, these presses can also be found at junkyards or car factories where assembly lines use hydraulic presses as part of their assembly lines.

Joseph Bramah came from a yeoman farmer family in northern England. As part of his experimentation, Joseph found that liquid power could be harnessed using cylindrical seal-fit cylinders sealed with leather seal-strips sealed by self-tightening collars to form hydraulic presses.

Today's hydraulic presses are designed to fit easily into most facilities. Their reduced number of moving parts reduces potential points of failure while eliminating special safety equipment - making them a more cost-effective solution than other forms of machinery. Plus, they produce equivalent power in half the space; helping your company reduce carbon emissions while increasing efficiency.
