The Turbo-V 2000HT series pumps are turbo-molecular pumps
for high and ultra-high vacuum applications and can pump any
type of gas or gas compound. They are not suitable for pump-
ing liquids or solid particles. The pumping action is obtained
through a high speed turbine (max. 33000 rpm) driven by a
high-performance 3-phase electric motor. The Turbo-V 2000HT
pumps are free of contaminating agents and, therefore, are
suitable for applications requiring a "clean" vacuum.
The following paragraphs contain all the information necessary
