Yeah, that's what I was hopping to see in the bottom of my keggle. I know it won't be quite as good a cone given the dimpled bottom of the keg. Next batch, I will whirlpool hot and then single pass through the plate chiller into the fermentor and see where that gets me.
 
Well, I brewed again, whirlpooled hot and did a single pass through the plate chiller directly into the fermentor. Thanks for the advice because it worked. I had a nice mound of trub in the center of the keggle when I was done and I pulled clean (but no too clean) wort into the fermentor. This was a lager (DUNKEL) so the single pass through the plate chiller was very convenient. The wort hit the fermentor in the mid 40's F. Ales are going to be a little tricky because a single pass makes the wort too cold for ale fermentation temps. I gotta figure out the best way to throttle back the cooling water. Right now I am using a submersible sump pump to recirculate ice water through the chiller.
 
I wouldnt suggest this one.
Notice its say not for indoor appliances and the huge warning for California residents stating it doesnt meet the requirments for lead free brass now mandated in all the states for use with drinking water or human consumption... This is not really a good choice unless you dont believe lead is bad for consumption.
 
With this pump you must buy the stainless steel head. The plastic one is garbage.
Curious why exactly you say that?
I only ask because I use the cheaper DC plastic pumps myself (with BSP threads no less) and have no problems with them... I did spend the $6-10 to buy stainless camlock fitting on them so I'm not unthreading and threading fittings on them each time I use them. I have made hundreds of gallons with them now over the years with no issues short of me dropping one and breaking it which is why I mounted them now.
I wonder what real benefit short of surviving abuse by things like dropping it the stainless head could have?

Its for the cooling water through the plate chiller. The wort will not flow through it. Still a problem?

Because as soon as you try to screw any fittings onto it the threads strip. I wish I would have ordered the stainless and saved on the shipping. I have used other plastic pumps as well and threaded fittings onto them with no problems, but this pump doesn't seem that way. Most of the reviews I saw said the same thing and I figured I would be fine saving a few bucks going with the plastic head, but was wrong.

Gotcha.
Since these were originally sold in Europe and Australia they are most likely British standard threads which are slightly different that the ones we normally use in the states.. I guess the type of plastic might have something to do with it too since the dc p38 pumps I use also have the British threads but I have had no issues threading stainless fittings onto them with Teflon tape.

I'm surprised the stainless heads work better since I would have expected the same BSP type of threads and that would be harder to fit to another standard of thread type. Funny thing though is depending on where you buy the stainless fittings you might end up with BSP threaded fittings.. some sellers don't advertise which they actually sell.. Even my bayou classic kettles appeared to have come with BSP threaded fittings and ball valves which I had a tough time with threading up to some of my fittings.

They are British standard threads and are advertised, so I knew that going in. Like you, I have used cam lock or tri-clover fittings before on British Threads, so I figured I could get it to work. I think you might be right it has something to do with the plastic. The stainless head had no problems at all. I can't fault them since I saw previous reviews that had the same issue. On the plastic I tried using with Teflon and without and both ended up stripping out. Overall I have been very happy with it.
 
It wouldn't in the cheap pump category, but Northern Brewer has added another candidate to the wort pump category. What I like about it is that it is 24VDC, which is much safer than 120VAC. http://www.northernbrewer.com/the-steelhead-2-pump

There's nothing new about this pump but the much higher price through this mainstream distributor vs Amazon and eBay were many people got them for like half the price up until now... if you do a search for "Dc pump" here youll see they have been available in this form as well as all plastic for as little as $30 for a couple years now.

I looked on Amazon, and could not find a comparable pump. and none with a SS head.
 
tangential zombie revival:

I personally have a Iwaki knock-off (Resun) pump which has a 1/10 HP motor on it (read: 2x the power of a Chugger - although only ~15% more head)

could you provide a few more details on this Resun pump? i checked out aliexpress and could only find air (not liquid) pumps by Resun. does this pump handle boiling liquids?

cheers! :mug:
