Filter
NOTE
Use a filter with laid-in wire mesh (mesh size max. 0.25 mm) made of corrosion-resistant
material.
Use a filter with a filter area three times the cross-section of the piping.
Conical filters have proved suitable.
4. Connect the pump nozzles with the piping.
CAUTION
Aggressive flushing and pickling agents
Damage to the pump!
▷
Match the cleaning operation mode and duration for flushing and pickling
service to the casing and seal materials used.
