2. Accurately insert the sealing element.
3. Connect the pump flange to the pipe flange by means of screws.
4. Tighten the screws hand-tight with an assembly tool (e.g. wrench).
5. Accurately insert the sealing element on the opposite side.
6. Connect the pump flange to the pipe flange by means of screws. Tighten the
screws hand-tight.
5.4 Connecting the piping
DANGER
Excessive loads acting on the pump nozzles
Danger to life from leakage of hot fluids!
▷
Do not use the pump as an anchorage point for the piping.
▷
Anchor the pipelines in close proximity to the pump and connect them without
transmitting any stresses or strains.
▷
Take appropriate measures to compensate thermal expansion of the piping.
CAUTION
Contamination/dirt in the piping
Damage to the pump!
▷
Flush the piping prior to commissioning or replacing the pump. Remove any
foreign matter.
NOTE
Installing check and shut-off elements in the system is recommended, depending on
the type of plant and pump. However, such elements must not obstruct proper
drainage or hinder disassembly of the pump.
✓
Suction lift lines have been laid with a rising slope, suction head lines with a
downward slope towards the pump.
✓
The nominal diameters of the pipes are equal to or greater than the nominal
diameters of the pump nozzles.
✓
The pipelines have been anchored in close proximity to the pump and
connected without transmitting any stresses or strains.
1.
Thoroughly clean, flush and blow through all vessels, pipelines and connections
(especially of new installations).
CAUTION
Welding beads, scale and other impurities in the piping
Damage to the pump!
▷
Free the piping from any impurities.
5.5 Casing/insulation
WARNING
The pump takes on same temperature as the fluid handled
Risk of burns!
▷
Insulate the volute casing.
▷
Fit protective equipment.
