Installation
35/ 100
Oleolift-C
Pressure line DN 100 (all NS with DL 100)
Flange connection dimension according
to DIN 2501/PN 16.
Î
Connect the on-site pressure pipe with
the on-site seal and on-site fastening
material on the flange.
Creating the backflow loop in the pressure pipe
Based on the normative requirements, the unit should drain via a backflow loop. The backflow
loop must be established above the backflow level. The installation example shows the basic
layout, Chapter 3.1 “Installation example”.
Definition of terms in accordance with EN 12056-4:
■
“Back flow”: Wastewater return pressure from the sewer into the connected pipes.
■
“Back flow level“: The highest level to which water can rise within a drainage system.
■
“Back flow loop“: Part of the pressure pipe of a wastewater lifting plant above backflow level.
Î
Lay the backflow loop above the
“backflow level”

3.3.9 Installing on-site direct suction (optional)
IMPORTANT
Before the on-site direct suction pipe (version as right or left) is installed, the
excavation pit must be backfilled up to this height, Chapter 3.3.12 “Backfill excavation pits”.
Specifications:
■
Direct suction, pressure pipes and/or suction pipes must be designed and implemented with
at least pressure rating PN 6. Utilise tension-resistant connections (maximum strength 1.5
times the pump pressure of the suction carriage) for individual pipes and fittings.
■
Install direct suction made of corrosion-resistant materials (e.g. plastic pipes made of PE, PP).
