Inlet Screen Installation - Varian Turbo-V 81-T Bedienungshandbuch

INLET SCREEN INSTALLATION

The inlet screens mod. 969-9300 and 969-9309
prevent the blades of the pump from being dam-
aged by debris greater than 0.7 mm diameter.
The inlet screen, however, does reduce the pump-
ing speed by about 10%.
The inlet screen is fitted in the upper part of the
pump, as shown in the figure.
The screen can be mounted on each pump.
The screen can be removed as shown in the fol-
lowing figure.
The following figure shows the overall flange di-
mensions with the protection screen fitted on
pump with ISO flange and pump with CFF flange
(dimensions are in inches [mm]).
