Magnochem-Bloc
6.1.2.1 Priming and venting horizontally installed pumps
Priming and venting for the operating modes: internal circulation, external
circulation and low-boiling fluids
1. Vent the pump and suction line and prime both with the fluid to be handled.
2. Fully open the shut-off element in the suction line.
3. Fully open all auxiliary connections (barrier fluid, flushing liquid, etc.).
Priming and venting with the dead-end configuration operating mode
DANGER
Impermissibly high temperatures; dry-running of the plain bearings
Damage to plain bearings and magnetic coupling!
Explosion hazard!
▷ In dead-end configuration operating mode, vent the rotor space and the heat
exchanger separately from the hydraulic system.

Filling the rotor space and
heat exchanger
CAUTION
Solids and/or ferromagnetic particles in the fill liquid
Damage to pump and heat exchanger!
▷
The fill liquid used to fill the rotor space and heat exchanger must be free from
solids and ferromagnetic particles.
NOTE
The process of filling the rotor space and heat exchanger can be monitored with
the help of a level transmitter (e.g. Liquiphant) fitted at connection 10H.
1. For venting, remove screw plug 903.Z6 from connection 5B at the heat
exchanger.
2. Remove screw plug 903.80 from connection 10F at casing cover 161 and fill rotor
space and heat exchanger with the appropriate liquid.
