need help with parts connecting pump and jamil chiller

[Nyakavt]

The cheapest brass QDs I could find from McMaster:

here's what I was thinking, this set up allows me to disconnect from the kettle out, but not the pump in (assuming I clamp down on everything that is barbed).
I can also disconnect from the pump out after the ball valve, but not from the chiller in.
does anyone see why I would need to disconnect from the pump in, or any other problems or ways to make this better.
thanks

That will work fine - but in my opinion - you don't want to permanently connect hoses to any equipment - be it a pump or a chiller. Get two extra disconnects and you are good to go.

There are (at least) two immediate benefits. 1) you can disconnect your pump, and still have a sanitized hose already connected to gravity feed to your carboy, or 2) you can disconnect your JZ chiller and have a hose (and pump) already connected to pump up to your fermenter. Plus, it's easier to clean that way.

Maybe it's just me, but I have never liked the "non linear" QD setups (ie. female ends on all hoses, male ends on everything else). I prefer that every hose has a male and a female - that way I can always string them together for any purpose (without using an adapter).

Oh, and BTW - the stainless QD's from B3 are f-ing awesome. I even saw a few on Denise's equipment at Moylan's.

I'm working on buying enough QDs to make everything so I can disconnect. NOT CHEAP.

Hadn't thought much about being able to chain hoses together, good idea.

The QDs are a must, specially if your tap water temp is higher (summer) you can easily chill your batch as low as your tap will allow, then add in a pre-chiller in a bucket of ice to push it down to lager temps. There are some flow losses but it works great.
Good luck, and I think you will really enjoy how well it all works.

P.S. Mylo - it was nice meeting you at NHC.

I am getting ready to Q/D my whole set-up. It seems like the best plan is to use Female Q/Ds on the "IN" side of everything and Male Q/Ds on the "OUT" side. This would allow all hoses to be strung together and any piece to be inserted in the flow of wort or beer at any point. Does that make sense?? Also, I assume the Q/Ds are not auto-shutoff.

My logic goes as follows; female couplers (QD's) on the hoses, male nipples (QD's) on the equipment. See layout below for the boil/chill/transfer side of my Hobby. I use stainless braid teflon core hoses, at about $5/ft. I want to be able to use these hoses for multiple services given their robustness and cost. Thus the same layout throught the brewery.

I am concerned about the ball valve being mounted directly on the pump housing. Polysulfone has a low tensile strength (11.2 Ksi) comapred to Brass and Stainless (>>50KSI). I chose, based on gut feeling, to plumb to the pump vs. hang any valving off it, but maintained the use of SS QD"s throughout the whole system. FYI.

Love the cart set-up as a future plan for me. Can you explain your concern or describe your March pump to ball valve connection? I was thinking ball-valve direct to march pump, but could certainly insert a set of Q/Ds between the two if that is what you are getting at.

Thnx.

Hey Timmy.

It is not a decision based on emperical data, as I have never heard of any failed male pipe ports on the March PS pump, but I used QD's on the pump so that I was not hanging a lot of weight off of them and was not imposing that "Moment" from actuating the ball valve if it is installed directly on the ports. I also like the idea of using any of my hoses on any component, and beiong able to swap out any components and fast setup with all QD's.

To get back to the first point. you will actuate that ball valve many times. I just do not know if the pump male port pipe molded and machined fitting can handle that over time, especially at 212F transfer temp, as polymers soften with higher temps (I am stating the obvious there ).

I just do not want to have to buy another pump housing, just in case.......

Take care! Happy brewing.

PS As for Immersion vs. Counterflow chillers - counterflow always wins (Log Mean T Diff. vs Static Cooling) - This is a fun experiment that P.G. Babcock. Can not talk to its authenticity. Check it out. Woul dhave been nice if he had a better conclusion section.

For efficiency, heat exchangers are designed to maximize the surface area of the wall between the two fluids, while minimizing resistance to fluid flow through the exchanger. trying to remeber some of my old heat transfer classes

so, is that link about the chiller saying that the cfc cooled the entire volume of the wort to 68F in 3 mins?
