Best way to transfer bulk hot liquid

34 posts in this topic

Someting like this may work:

Also, I remember there is another kind of pump which can work. It is basically a round tube squeezed continually by two motorized wheels rotating in one direction. It is self-priming (poitive displacement pump without a piston.)

What kind of tubing does one need to use in order to accommodate hot liquid?

Silicone but it is expensive. We use it in brewing.

Dcarch- it's called a peristaltic pump.

If moving the liquid were a usual part of the work flow I would recommend a peristaltic pump. Very easy to clean, robust, quiet, self-priming, does not shear the fluid much.

Cleaning a drum pump is not that problematic. There are no valves and pistons. It's like a centrifugal pump, except centrifugal pump is not self-priming.

A peristaltic pump is ideal, but difficult to find one with high capacity.

Then I'm willing to bet my March 809 pump is a "drum-pump". Has a magnetic impeller, is not self-priming and its use has a sharp learning curve. I bought it to transport and circulate boiling wort and water for my brewery.

Cleaning a peristaltic pump isn't as difficult as one would imagine. You pump hot water and cleansers through and the tubing can be detached and cleaned as well. A device for transporting food grade materials needs to be easily cleaned.

Depending upon how much I've got to transfer, I, too, usually press a saucepan into duty. Or a large Pyrex measuring cup.

Or, I also have one of these: http://www.seattleco...a_7cCTC785B0020

It's called a 'cezve,' a Turkish coffee pot. I bought it years ago because Bananas Foster was my "go-to" dessert for dinner parties. Not only does it look great on the tabletop, it was easy to put the thing on the stove burner, pour in the liquor, heat it, light it with a fireplace match, and then pour the flaming liquid into my chafing dish with no fear of burning my fingers.

But it also works just great for scooping boiling hot liquids in order to transfer them.

I don't understand why rappers have to hunch over while they stomp around the stage hollering.  It hurts my back to watch them. On the other hand, I've been thinking that perhaps I should start a rap group here at the Old Folks' Home.  Most of us already walk like that.

A centrifugal pump can be CIPed. A vane pump cannot - and I am sure many of them cannot be disassembled for COP.

My tube came from a beginners brewing kit. If you have a homebrew store near you, you should be able to pick one up for a few bucks.
