Powerlift prefabricated pumping station
■
Choose resistant material (e.g. KML, PP, PE, PVC).
Î
Use acid-free lubricant to grease the
spigot of the vent stack and the sealing
lips of the socket seal.
Î
Push the spigot into the socket seal.
3.3.8 Laying and connecting the on-site blank cable pipe
IMPORTANT
Before the on-site reserve cable conduit is connected, the excavations must be
backfilled up to this level, Chapter 3.3.11 “Backfill excavations”.
Specifications:
■
Pipe nominal widths DN/OD = 110 mm and/or DN/OD = 160 mm with PSD-B-2200/
T
Basin
585
■
The reserve cable conduit must be laid as always rising from the tank to the assembly
location of the control unit (technology room and/or outside cabinet). Do not reduce the
stack cross-section.
■
Do not use pipe bends with angles larger than 30°.
■
Lay a high-quality pull wire in the reserve conduit directly at the same time.
■
Choose resistant material (e.g. KML, PP, PE, PVC).
Î
Use acid-free lubricant to grease the
spigot of the reserve cable conduit and
the sealing lips of the socket seal.
Î
Push the spigot into the socket seal.
3.3.9 Laying and connecting the on-site pressure pipe
IMPORTANT
Before the on-site pressure pipe is connected, the excavations must be backfilled
up to this level,
Chapter 3.3.11 “Backfill excavations”.
Based on normative requirements:
■
The pressure pipe must be designed for at least 1.5 times the pump pressure.
■
Lay the pressure pipe so that it rises continuously and is frost-resistant.
■
The flow velocity in the pressure pipe must not fall below 0.7 m/s and must not exceed
2.3 m/s.
■
Never connect other pipes to the pressure pipe.
■
Air admittance valves are not allowed in the pressure pipe.
