Flooded suction
When dosing degassing media or media with a higher viscosity than that of water, the suction lift
will be reduced. In these cases, flooded suction may be required.

2.1.2.5 Siphon effect
The pressure at the outlet valve (p2) must always be at least 1 bar higher than the pressure at the
inlet valve (p1). If this is not the case, for example in an installation with open outflow or with floo-
ded suction, siphon effect may occur. To avoid the siphon effect, install a pressure-loading valve
(7) in the outlet line and an isolating valve (11) directly before the inlet valve.
