4.7 CHIEMSEE in suction operation
By using the non-return flap, which is available as a Spechtenhauser accessory, with a
transparent hose (length up to 5 m) suction operation of the pump is also possible. All
couplings used on the suction side must be clean and leak-proof. As
soon as air is able to enter the system on the suction side, pumping
is no longer possible. Basically suction operation can only be carried
out up to a maximum fluid temperature of 40°C.
If the pump is to be used in suction mode, the following points are to
be observed:
1. Mount the non-return flap to the transparent suction hose.
Caution:
Only the non-return flap from Spechtenhauser is to be used. Suction operation with ball
flap valves is not possible. Only use a transparent suction hose as a suction hose.
2. Connect the suction hose to the suction side of the pump.
3. Fasten a spiral hose to the outlet side of the pump.
4. Pour water into this pressure hose only until the suction hose, the pump and the pres-
sure hose are filled with water. If necessary, the flap of the non-return flap will also have
to be opened for ventilation.
Important:
The non-return flap must be loaded with at least 1.5 m water column so that it is com-
pletely watertight.
5. Lay the suction hose in the medium to be pumped. Ensure that the non-return flap is
not on the ground but is about 20 cm above the ground. This prevents stones from being
pumped.
6. Lay the pressure hose properly (see section 4.2).
7. Switch on the pump.
