The pumping speed against pressure graph for a vacuum booster pump is not a smooth curve. The graph varies from manufacturer to manufacturer even though the pump design is based on the original Roots design. The pump speed curve is similar to a bell-shaped curve and rises to a peak from startup and then drops off as the pressure drops. (Fig. 3)

Jan 13, 2016 · When designing or operating a vacuum system, it is critical to understand the function of the vacuum pumps. We will review the most common types of vacuum pumps, their principles of operation and where in the system they are used. Vacuum pumps are categorized by their operating pressure range and as such are classified as primary pumps, booster pumps or secondary pumps.
