Inlet Screen Installation - Varian 969-9357 Series Instruction Manual

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 either pump series
and is supplied with a small tab for easy removal
(see figure).
The following figure shows the overall flange di-
mensions with the protection screen fitted on
pump with ISO flange (on the left side) and pump
with 4.5" CFF flange (on the right side).
