5.2 Avoiding siphoning
If there is a height difference
ΔH
between the suction side and
pressure side container side / system, the low lying line can
develop a suction effect and trigger the siphoning effect be-
tween the communicating containers / systems. This siphoning
effect also occurs when fluid is pumped in a pre-pressurized
reservoir.

Siphoning effect
Reservoir overflowing/leaking = oil spill
u
Remove the ends of the hoses from the reservoir after op-
eration or shut the shut-off device in the suction line.
After the filter unit is switched off, the height difference or pri-
mary pressure can cause the flow to occur both in and against
the feed direction and the fluid can leak uncontrollably.
