TECHNICAL INFORMATION

INLET SCREEN INSTALLATION

The inlet screens mod. 969-9302 and 969-9303
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.
