Danger!
The rotating impeller can cut or crush
hands and arms.
Safeguard the pump when checking
the direction of rotation.
Do not reach into the pressure flanges
or the intake port of the pump casing.
Caution!
Dry running the pump will destroy the
mechanical seal!
After starting up the pump switch it off
again immediately.
It is possible to activate the pump temporarily for max. 3
seconds without the risk of dry running.
Each pump is to be inspected individually in the case of a
control system with multiple pumps.
The direction of rotation
corresponds to the rota-
tion indicator arrow!
Important!
This must rotate clockwise when looking at the motor fan.
In pumps of the UNIBAD-XC series the motor shaft has to
rotate clockwise from the direction of the motor cover.
Openings in the intermediate casing allow a glimpse of the
motor shaft.
