4.3 Liquid temperatures/cooling
The maximum liquid temperature and the minimum
flow velocity past the motor appear from the
following table.
Grundfos recommends installing the motor above the
well screen in order to achieve proper motor cooling
via liquid passing the motor.
If there is a risk of sediment build-up, such as sand,
around the motor, a flow sleeve should be used in
order to ensure proper cooling of the motor.
* At an ambient pressure of minimum 1 bar (0.1 MPa).
** At an ambient pressure of minimum 2 bar (0.2 MPa).
Note
If the stated flow velocity cannot be
achieved in the borehole, a flow sleeve
must be installed.

Note
For 37 kW MMS6 (only PVC windings),
110 kW MMS 8000 and 170 kW
MMS 10000, the maximum liquid
temperature is 5 °C lower than the values
stated in the above table. For 190 kW
MMS 10000, 220-250 kW MMS 12000/50
Hz and MMS 12000/
60 Hz, the temperature is 10 °C lower.
