Fig. 8-16: Overview of the cooling connections
To supply the MAF motors with cooling liquid, you will need additional
installation material, e.g. hoses and fixing clamps. These are not included
in the delivery of the motor
.
Select the supply hose with the correct inner
diameter d
i
.
The customer’s equipment is threaded directly into the motor. The
motor`s threads are plugged with factory-attached protective caps.
In the following illustrations, the assignment of inlet (IN) and outlet (OUT)
is made for reasons of standardization; it does not affect the performance
data of the motor. Existing installations with other assignment can be
retained.
Operating Pressure
A maximum coolant supply pressure of
3 bar
applies to all MAF motors.
This is to be read directly at the coolant connection of the motor.
Please note that additional threads or branches connections in the cooling
circuit can have a negative influence on the flow and supply pressure of
the coolant.
