10.1.3 Installation suction line (general instructions)

Please note:
Keep the suction line as short as possible!
Size the diameter and length so that the underpressure arising
when sucking does not reach the steam pressure of the media to
be fed!
The suction line must be laid ascending in order to prevent air
bubbles from forming!
For bends use arcs and not angles if possible!
Please note:
Too high underpressure on the suction side in extreme cases
leads to the fluid column tearing or an incomplete return stroke!
NB:
Height (h) x density (d) ≤ max. suction lift in mWC!
