Etaprime L
NOTE
Use a filter with laid-in wire mesh of 0.5 mm x 0.25 mm (mesh size x wire diameter)
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.
2.
Connect the pump nozzles to the piping.
Observe the distances stated above (see illustration: Distances of suction and
discharge lines).
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.

Forces and moments
at the pump nozzles
The data on forces and moments apply to static pipelines only. The values are only
applicable if the pump is installed on a baseplate and bolted to a rigid and level
foundation.
