What pumps for a water chiller setup?

[CreePinG_DeatH]

I was wondering what kind of pump do people use for water chilling setups? I believe my water will be held at around -40c (probably higher underload). What brand/model is the popular choice? Inline? Submersible?

Thanks.

Don't know about others. I have got this pump for the chiller I'm building

awesome thanks for the feedback. I'll start looking at pond pumps.

Definately submersable. It's much easier to adapt tubing. Most inline can be run submersed.

Can you use a pump that will not be submersed? Such as a normal WCing pump?

As long as it can withstand the temperature and the electronics are all insulated from water, I don't see why not.
