Characteristics of magnetic coupling RVM.
Continual research by the R+D+I department in Pedro Gil and over 40 years experience manufacturing Roots type vacuum pumps, has resulted in one of the most important recent improvements.
The elimination of a dynamic seal for the drive shaft and its replacement by magnetic coupling gives a tighter static closure, significantly less leakage and considerably lengthens the life of the pump. Roots type vacuum pumps RVM activated through magnetic coupling provide clear advantages over conventional pumps. The leakage rate is much less, such that the vacuum working level can reach 10-5 mbar, providing much better performance in the high vacuum range. The tightness of the compression chamber is achieved through locking segments or specific closures for particular applications.
