|
|
All,
I was installing my disconnects and valves tonight and had a question about the pumps. I am using Chugger pumps with stainless head. I was reading over at HBT that outlet orientation does not matter(well don't put the outlet on the bottom). The default chugger is inlet on left side bottom(which actually channels it to the direct middle of the pump) and the outet is on the top, but the connection is on the top right. I was thinking about rotating it 90, so the outlet connection is on the top, but that would actually mean the outlet of the impeller is on the left side. I plan on using a T and adding a dump valve, so I will be able to vent air if I have a priming issue.
Any one have any opinions or thoughts?

I have those chugger pumps and I did exactly what you are describing. While I have yet to fire them up I can't imagine there would be a problem. I think the paper that came with them said that they could be oriented anyway you wanted (except with the outlet facing down obviously) so I never thought twice about it. I'm still a ways away from trying it out for the first time so I can't say with certainty.

I mounted my chugger pumps with the outlets pointed up and they work great. Any air in the inlet side gets pushed up and out the outlet.

Thanks Kal, I had to find another use for my Greenlee hole punches . www.onlinemetals.com has a great selection of ss that can be cut to order too.

I've heard of people having trouble with getting air in the pumps. Usually the fix is to mount the outlet at the top, as MillWorks has done.
mildoggy, the dump valve sounds like a nice idea, can you explain a bit more? With my limited plumbing skills I can't quite picture it - I just imagine water or wort squirting everywhere! Is it possible to bleed out just the air?

basicly run a T out and a ball valve on each outlet from the T, one with a disconnect, one with a barb and a hose. This lets you purge air and take samples. Below is a bad photo.
I grinded my street elbows tonight, I am using them as right angles into my camlocks. I took the threads off to make a nice connection.

Thanks for taking the time to take a photo, now I get it. Have you tried it? I'm guessing that as you bleed the air, it will be replaced by more liquid. And perhaps even if there is still some air left it won't affect pumping since it occupies a space above the flow of the liquid. Nice!
And a nice job on those elbows! I also bought the camlocks but decided just to go with regular fittings. I don't have a grinder and didn't fancy spending 3-4 years doing it with a dremel! It surprises me that the hoses stay on with the outside of the elbows so smooth.

The bleeder lets you flood the pump with out it on, close the output valve, open the bleeder valve, open the valve on your pot. Close the bleeder when liquid comes out, pump is now primed. The bleeder also lets you pull samples for your refractometer. You could use an autovent if you want to autoprime.

I guess there are no Harbor Freights in Norway? If you really wanted, I could grind them and send them to you. Took me about 1.5 hours.

Crush, why would you need a grinder for the camlocks?

The dump valve sounds like a good idea!
There's no Harbor Freights here, Thanks, thats a very kind offer! Alas, I've ordered my cams - I went for mostly C and F type - male barbed connector on the hoses, since I knew grinding the elbows would be a problem for me, and I didn't have your kind offer when I ordered!

I pulled the heck out of them, there is tons of friction and the hose clamp, I really doubt they are coming off. They are stretched over the fitting more thats a barb.
