7. Inlet pipe
B: Installation precautions for inlet
pipelines
1. While installing the electric pump, do
not use too soft rubber tube for the
inlet pipeline, avoiding to be sucked
flat.
2.
The foot valve should be vertically
placed and
from water bottom to avoid
sucking in sands and stones (B2)
3. Joints of the inlet pipelines
should be sealed with the least
elbows; no water can be sucked.
4. Diameter of the inlet pipe should
be at least in accordance with
that of the water inlet, to avoid
too much water loss which will
influence outlet performance.
5. Pay attention to drop of water
level while using, the foot valve
should not be above the water
surface (B1).
6. In case the inlet pipe is longer
than 10m or its lifting height
exceeds 4m, the pipe diameter
should exceed diameter of water
inlet of the pump.
7. Ensure the pumped will not be
affected by pipeline pressures
while installing the pipelines.
8. Filter should be installed in inlet
pipelines so
solid particles to pump.
C: Installation Precautions
outlet pipeline
Pipe diameter of the outlet pipeline
should be at least in accordance with that
of the water outlet, so as to reduce its
voltage drop, high flow rate and noise to
the minimum.
