Standard Rack Controller Compatible
Vent Valve mod. 969-9843
This vent valve has a fixed delay time of about 5
sec. This time can be increased up to about 220
min. by means of a setting of the Navigator soft-
ware (optional).
To install the vent valve execute the same steps
as the vent valve model 969-9834 (see the above
paragraph).
Vent Device mod. 969-9831
The vent device has adjustable delay time (up to
36 min.).
To install the vent device unscrew and remove the
threaded plug (see figure below).
Screw the flange mod. 969-9108 on the pump, tak-
ing care of the o-ring right position.
Assemble the seal ring and lock the vent device in
position using the KF klamp.
VIBRATION ISOLATOR INSTALLATION
Single Damper
Two vibration isolators for ISO 200K and ISO 200F
inlet flange version pumps are available as acces-
sories.
The two model part numbers are the following:
−
model 969-9346 for ISO 200K flange;
−
model 969-9374 for ISO 200F flange.
They typically reduce the vibration transmitted
from the TV 1001 SEM to the system by a factor G
that depends on vibration frequency. In the follow-
ing table you can find the values of G for the most
relevant peaks in the pump vibration spectrum.

Where "axial" is the same axis as spin axis of the
rotor, and radial is perpendicular to it.
