INLET SCREEN INSTALLATION
The inlet screen mod. 969-9302 prevents the
blades of the pump from being damaged 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 model
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 and pump with CFF flange.
