These vacuum pumps are suitable for pumping non corrosive gases.
The main features are:
all parts in direct contact with the fluid pumped are free of
copper alloys;
all materials are carefully selected to provide extended life;
a high capacity gas ballast device allow to pump condensable
vapors;
all the parts composing the pump are fully replaceable due to the
close machining tolerances and to the centering obtained by
using reference pins;
