Neck rings
The pump is optionally equipped with exchangeable neck rings. During operation, the
gap backlash increases due to wear. The period of use of the rings depends on the op-
erating conditions. If the volume flow decreases and the motor shows signs of in-
creased current consumption, this could be caused by an impermissibly high gap back-
lash. In this case, replace the neck rings.
