SONIC300077 There is an idea to make a water-cooled extruder using a peristaltic Pumpe. There is an unused driver boards always. It remains only to add the settings to the firmware. The basic setting is the motor speed. It would be nice if it would be possible to change the EEPRUM. You can also add a switch on the motor after 50 degrees Celsius.
Repetier Why not using a dc motor for a pump, then you could use the cooler pin to enable/disable motor.

SONIC300077 there is still such a moment that, if unregulated molasses will be hypothermia, stepper motor and peristaltic pump is perfect for that!
