Buzzing motor frrom coolant pipes.

This is probably a very simple thing to sort out but I dont have the time to find out the hard way so her goes.

Ive got a 2.4d 93 plate. I get a buzzing constantly from a motor/pump that is connected between coolant pipes at the front of the motor below the FIP. It draining the battery over a period of a week if I dont use my van. I take it , its for extreme cold weather to stop the coolant freezing?

IS it supposed to buzz constantly?

Apart from disconnecting it, is there a way to stop it?

Is there some sort of solenoid/switch/sensor that controls it?
