Notes concernant l‘installation de la tubulure
d Notes for inlet pipeline installation:
1. Do not use soft rubber tube for inlet
pipeline during pump installation.
2. The bottom valve shall be vertically
installed with a distance of 30 cm from the
water bottom to avoid suction of sediment
(B2).
3. All connections of the inlet pipeline must be
sealed. To ensure water suction, it’s
necessary to reduce the quantity of bents
of the pipeline.
4. The diameter of inlet pipeline must not be
less than that of the pump inlet to avoid big
hydraulic loss and small water flow.
5. Pay attention to the water level during
operation. The bottom valve shall not be
above the water surface (B1).
6. In case the inlet pipeline is more than 10 m
in length or over 4 m in hoisting height, the
diameter of the inlet pipeline must be
bigger than that of the pump inlet.
7. Make sure that the pump is not affected by
the pipeline pressure during pipeline
installation.
8. It is recommended to install a filter on inlet
pipeline to avoid incoming of solid particles
to the electric pump.
9. Before first operation, the inlet pipeline
must be fully filled with water and installed
with a bottom valve.

Note for outlet pipeline installation:
The diameter of the outlet pipeline shall be not
less than that of the pump outlet to reduce the
pressure drop, high flow rate and noise to the
lowest level.
