Vacuum pumps have been around for several centuries, preceding the vacuum pumps were suction pumps, which were invented in 1206 by an inventor and Arabic engineer, Al-Jarazi. order viagra online uk Although some rudimentary vacuum pumps were invented no one understood exactly how they worked. By the 1700’s the water pump design had improved so much that they produced measurable vacuums. Although they didn’t understand the science behind it, they did understand that water could only be pull to a certain height, about 8 or 9 metres. This was a problem for decorative water fountains, Viagra Jelly irrigation projects and mine drainage. The Duke of Tuscany commissioned Galileo to solve the problem. Galileo in turn advertised the puzzle to other scientist. The breakthrough came from Evangelista Torricelli in 1643. Using Galileo’s notes he built the first mercury barometer and wrote a convincing argument that there was a vacuum at space at the top. The height of the column was limited then to the maximum weight that pressure from the atmosphere could support.

In 1654, Otto Van Guericke, a German scientist, inventor and politician, invented the first vacuum pump and conducted a famous experiment where he harnessed a team of eight horses to each end of his hemisphere and tried to get the horse to pull it apart. Of course, cialis price this was impossible. Later he demonstrated the same experiment using 24 horses, again to no avail. He disproved the old hypothesis that nature abhors a vacuum, which was the thought of the time and caused many problems for philosophers and scientists. Guericke proved that substances pushed by the pressure of the surrounding fluids not pulled by a vacuum.

Vacuum pumps are used in many areas such as brakes in large trucks, in most light aircrafts to drive gyroscopic flight instruments, the altitude indicator and the heading indicator, low pressure gas applications, auto exhaust emission control, in air conditioners, laboratory freeze dryers, they are used extensively in semiconductor systems along with many others.

Vacuum pumps led to rotary pumps and other pumps with virtually limitless applications.

We owe much to the early scientist for their tenacity and perseverance and letting go of the old thought processes to think outside the box so we might enjoy the benefits of these applications today.
