Section 7: PUMPING SPEED CURVES

HIGH EFFICIENCY PUMPING CHARACTERISTIC OF DUOSEAL® PUMPS

The low RPM design of DuoSeal vacuum pumps makes it possible to maintain high pumping effi ciencies 
into the low micron range.  High RPM direct drive vacuum pumps, on the other hand, experience a rapid fall 
off of pumping speed below 100 microns.  

A comparison of the DuoSeal pumping speed curves shown below, versus high RPM pump speed curves 
conclusively illustrates the superior performance of the DuoSeal pump. 

What does that mean for the vacuum pump user? 
DuoSeal pumps provide considerable faster pump down time in the low micron range.
