Industrial Vacuum Pumps Industrial Vacuum Pumps. Rotary vane: Rotary vane pumps are comprised of a series of vanes that are mounted to a rotor that turns inside a cavity. As the vanes rotate, centrifugal force extends them from their individual slots, forming compression cells that get larger to draw air in from the intake and smaller to push air out the exhaust.

Vacuum Pressure. By definition, vacuum is a space that is partially exhausted (as to the highest degree possible) by artificial means (such as an air pump). This definition is referring to a high or hard vacuum. Figure 1 illustrates that relationship of absolute and gauge pressure with 0 PSIA equal to a high or hard vacuum. Figure 1: Gauge Pressure
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 .
Since most roughing pumps will lose pumping speed as the chamber's pressure is lowered, the elapsed time to reach a lower-than-required pressure will be extended. The figure shows the pumpdown performance of a chamber where the crossover is accomplished at various pressures: 12 torr (maximum pressure), 0.8 torr, and 0.01 torr.
Jan 13, 2016 · High Vacuum: 10-3 Torr to 10-7 Torr; Ultra-High Vacuum: 10-7 Torr to 10-11 Torr; Extreme High Vacuum: < 10-11 Torr; The different types of pumps for these vacuum ranges can then be divided into the following: Primary (Backing) Pumps: Rough and low vacuum pressure ranges. Booster Pumps: Rough and low vacuum pressure ranges.

The Equilibar vacuum pressure regulator is ideal for use with dry-vane vacuum pumps because it produces a nearly flat pressure curve throughout the operating range of the pump. Such an approach allows the user to select the ideal vacuum level without having to compromise between the extremes levels at low and high usage.

These pumps can be used in conjunction with a secondary standard to provide accurate calibration pressures ranging from vacuum to 700 bar. Low and medium pressure pumps utilize air as the fluid and high pressure versions utilize inert calibration oil. All pumps include a fine adjust feature to enable precise pressure settings.

The gauge measures vacuum relative to external pressure (in this case atmospheric pressure) which is the only way to do it. The standard measurement is in inches of mercury, which basically means if there were a vertical straw in a bowl of mercury and the vacuum on the other end, the vacuum would be determined by how high into the straw the mercury is forced to go by external pressure. 30 .

To be able to compare capacities of different pumps, we need to calculate the actual capacity (ACFM) at different levels of vacuum. To be able to do this, we need to know the volumetric efficiency of the pump at a specific vacuum level (request this from the manufacturer), which can vary anywhere between 90% and 40%, depending on the pump design.
