Hello,
I'd like to control a pump with my arduino but it should be ok to push batter through it.
Do you know where I should be looking to buy such kind of items ?
Regards,

first thing that popped in my head was a modified meat grinder :-?
Is this for making like doughnuts or something?
How big of a batter batch are you looking to dispense?
I'd like to make pancakes.
The idea is to have a container full of batter and once the pan break a light ray a single serving of batter is dispensed in the pan.
It's a bit off topic but now that I think about it remote sensing pan temperature would be a nice add on.
they have those funnel things, where you push the button and it plops out enough for a pancake
you could use a solenoid to push the button I imagine
That is exactly the kind of thing I was thinking.
Something like this but on a smaller scale.
Just the batter head without all the other stuff to cook them. 
aye
Now that's a great find... ;D
I want two....
A homebrew peristaltic wouldn't be too difficult to build; use food-grade silicone tubing...
Thick material like dough and thick batters doesn't generally travel threw a pipe via a pump. Often its pushed threw using a large screw in a pipe. This also works well with dry goods. With the right size pipe and screw you could have either a full or a partial turn dispense the exact amount of the product you need.
