DANGER
Leakage at the pump
Leakage of hot fluids!
▷
Insert the O-ring in the correct position.
An arrow on the pump casing indicates the direction of flow.
NOTE
The direction of flow of a vertically installed pump should be upwards.
CAUTION
Air entering the pump
Damage to vertically installed pump sets whose direction of flow is downwards!
▷
Fit a vent valve at the highest point of the suction line.
NOTE
To prevent any impurities from collecting in the pump do not install the pump at
the lowest point of the system.
1. Place the pump in the specified installation position.
2. Accurately insert the sealing element.
3. Connect the pump and piping with a pipe union.
4. Tighten the pipe union hand tight with an assembly tool (e.g. pipe wrench).
5. Accurately insert the sealing element in the opposite pipe union.
6. Tighten the pipe union hand tight with an assembly tool (e.g. pipe wrench).
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.
