Installation recommendations
The CM-series pumps are normal-priming
centrifugal pumps and should be mounted in
a manner that ensures that they are always
flooded or else be primed before being
switched on. In a closed system the pump
should be placed at a low point.
The pump should not be run dry, even if it
withstands a shorter time of dry running. Max
dry running 30 minutes. Noise may occur.
Avoid dry running because it will always
cause increased wear.
Use full hose diameter at inlet. Reduced
hose diameter at inlet gives reduced
performance and risk of cavitations which
can cause damage in the pump.
The direction of rotation is clock-wise,
viewed from the front towards the body (see
rotation arrow).
The pump can be installed horizontally or
vertically, on a flat surface.
To avoid air-locks when mounted horizontally,
the body should be turned in such a way
that the outlet is directed upwards or is
placed on the upper side of the pump body
(see sketch). The outlet hose after the pump
must be horizontal or directed upwards to
evacuate air.
