Multiple Pumps working together

[Douglefish]

So I recently tried to whirlpool through my counter flow chiller on a 10 gallon batch. While the results weren't bad, I was hoping for better. I believe that the slow performance was due to the the March 809 pump not being strong enough to push my wort through my CFC fast enough.

A bunch of people on this board have single tier setups with 2 pumps. I was thinking, since I have 2 pumps, could I run them both full bore and inline? Would this speed things up, or with the mag pumps does this not make sense.

I'll probably go ahead and try it at some point when I get my rig fully setup, but wanted other peoples thoughts.

Thanks

I can't get my March to whirlpool even without a CFC inline. That's just going from the drain through the pump to a return tube on the IC.

Why don't you just use a hop bag? I believe you whirlpool to make all the sh*t collect in the middle, right? You could just easily filter it with a hop bag...

Running two pumps in series should work and you could easily do a test run with just water. Not sure how much that would improve the flow rate though. More than likely, the CFC is creating too much resistance. What is the ID of the CFC tubing? If you are trying to pump through the common 3/8" OD tubing, it will present a lot of resistance as the ID is only about 1/4" or so. That's like breathing through a soda straw. Not easy.

I use the whirlpool chilling method and pump through my CFC in a continuous loop back to the kettle. My CFC uses 1/2" ID pipe and I have the Little Giant equivalent of the common March pump. I haven't measured the actual flow rate, but it's fairly fast. I use this method to get a very fast temp drop for the entire volume, and not so much to create a trub pile, although both happen.

That's exactly what I'm trying to do. I want to drop the entire boil down in temp very quickly so that I can retain the aroma compounds like Jamil's whirlpool chiller. Problem is I have a CFC and just wanted to make it work.

I also want the ability to do light lagers, and it's nice to be able to get the cold and hot break to form before going into the kettle. Hop bag doesn't solve all of my problems.

You can do what we did on our single tier build. We are able to chill our wort down to 66 degrees in LESS than 6 minutes by using an Industrial stainless steel paint mixer attached to a 19v corldless DeWalt drill inside of our copper 3/8" wort chiller with NORMAL ground water from a garden hose.

We were VERY pleased at this(easily worth $50). We had the wort chilled down to 80 degrees in 4 mins FLAT!!!

Is the return to the kettle restricted? I used a piece of copper and flattened it, it makes a more powerful blast that gets the wort moving much better.
