Types of Pumps. Now, let's move on to vacuum pumps. We can sort them into 2 broad categories: Positive Displacement. A positive displacement pump moves a fixed amount of fluid and then guiding it into a discharge pipe. This allows the pumps to produce a continuous flow at a set speed regardless of the discharge pressure. Centrifugal

Ultra-high vacuum - Wikipedia

Ultra-high vacuum - Wikipedia

Ultra-high vacuum (UHV) is the vacuum regime characterised by pressures lower than about 100 nanopascal (10 −7 pascal, 10 −9 m bar, ~10 −9 torr).UHV conditions are created by pumping the gas out of a UHV chamber. At these low pressures the mean free path of a gas molecule is greater than approximately 40 km, so the gas is in free molecular flow, and gas molecules will collide with the .

History Early pumps. The predecessor to the vacuum pump was the suction pump. Dual-action suction pumps were found in the city of Pompeii. Arabic engineer Al-Jazari later described dual-action suction pumps as part of water-raising machines in the 13th century. He also said that a suction pump was used in siphons to discharge Greek fire. The suction pump later appeared in medieval Europe from .

Vacuum Pumps: Why use them & what do they do?

A vacuum pump has the inlet hooked up to one or both valve covers, sometimes the valley pan. It SUCKS the air from the engine, thus reducing the air pressure build up created by blow due to combustion gases going past the piston rings into the pan. Vacuum pumps vary in the amount of air volume (CFM) they can suck so the potential VACUUM a pump .
