The HS452 and HS652 pumps are rotary vane pumps oil sealed,
driven by a three-phase electric motor.
Figure 3
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;
