VENT DEVICE INSTALLATION
The vent device mod. 969-9831 allows to avoid
undesired venting of the pump during a temporary
power failure (adjustable time up to 36 min.), and
enables an automatic vent operation.
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
Two vibration isolators for ISO and CFF inlet flange
version pumps are available as accessories.
The two model part numbers are the following:
− model 969-9332 for CFF 6î flange;
− model 969-9342 for ISO 100 flange.
They typically reduce the vibration transmitted from
the Turbo-V 150HT pump to the system by a factor
of 20.
Please refer to the relevant instruction manual.
