ope­ ation. The integrated float switch
r
with its extremely compact design
allows an application in very narrow
sumps.

transportable.
Pumped liquid: Clear water or
drainage water containing soft solids up
to 10 mm spherical clearance.
Max. liquid temperature: 35°C, short
term up to 60°C.
Operation: Intermittent.
