E
Suction pipe clogged
Check the free flow of the pipe system on the
suction side.
F
Foreign matter in medium
Clean the pump unit. Install strainer in the suction
pipe.
G
NPSH
a
too low (medium
evaporates during feeding)
Increase the suction pipe diameter, shorten the
suction pipe length, simplify suction pipe assembly,
reduce the suction height, reduce the speed, adjust
the medium temperature.
"Installation in pipes"
H
Belt tension too low
Tighten in accordance with manufacturer's
specifications.
"Base, support surface for
machine"
I
Coupling not correctly
aligned
Check the orientation and align according to
manufacturer's specifications if necessary.
J
Belt drive slips
Tighten in accordance with manufacturer's
specifications.
