WARNING
Risk of scalding!
At high fluid temperatures and system pressures, allow the pump to cool
down first and then depressurise the system.
CAUTION
Damage to the pump due to overheating!
The pump must not be allowed to operate dry for more than 1 minute.
Dry running causes a build-up of energy in the pump, which can damage
the shaft, impeller, and mechanical seal.
• Make sure that the volume flow does not fall below the minimum
value Q
min
Approximate calculation of Q
Q = 10 % x Q
min max pump
The component arrangement related to the pump housing is pre-assembled at the factory
(see Fig. 8) and can be changed on site as required. This may be necessary, for example, in
the following cases:
• Ensuring pump venting
• Enabling better operation
• Avoid impermissible installation positions (motor and/or electronic module point down-
wards).
In most cases, it is enough to rotate the motor impeller unit relative to the pump housing.
The possible arrangement of components is the result of the permitted installation positions.
