Water pump for condensers. What kind of pump should I use to cycle water through my jackets?


If anybody could send me a link to a website where I could purchase a good water cycling pump for my condensers, it'd be much appreciated. I simply cannot even find any info on it. Slightly irritating



Just trying to figure some stuff out you know?

A submersible aquarium or fountain pump should be adequate; google it. It shouldn't be a problem to find it locally.

Pump


I use a standard fountain pump from Lowe's submerged in a 1.5Gal container and use those reusable ice packs for coolers (3) and get very near 0C coolant water. I don't remember my pump size but I know it's not the smallest and has ~1/4 outlet size.

Any small water pump is fine, they sell many that would work for $20-50. Try a hardware store, fish supply store, or walmart. As stated above, a 1/4" outlet is ideal, and a 5 gal or smaller bucket is fine. I like the reusable ice pack idea, that is even better than ice. Almost any pump will do.

I have a 65gph fountian pump. Anything 40-80 gph should be good.

I use a fountain pump I bought at Home Depot for 20$... The nozzle is easy to slip latex tubing over to connect to your condenser or whatever. The reuseable cold packs are especially nice, I have 6 and I use two in the reservoir at a time so that if I run a long experiment I can simply swap them with fresh ones from the freezer!

Just look in the garden section of Home Depot or any other home improvement store.

If you look around long enough, you can find one for 14 bucks online. This includes shipping! I personally wouldn't spend more than a total of 20 bucks. There's quite a few you can find under that price.

While the idea of using a cold pack sounds great, it's can't compete with just using ice. I find that it doesn't get cold enough... In combination with ice, cold packs works great but alone I wouldn't use it unless I had no other choice.

Depends on what you're distilling, how much of it, and how long you're doing it. I exclusively use tap water (I don't "recycle" it) which is just fine for most of my applications.

Could I get the tubing in the same place as the pump do you think? I appreciate the quick replies.

I use 1/4 ID tubing from the local hardware store for most of my lab chores. Cl2,HCl and other gasses will make rather short work of it but I have had no issues using it for condenser work. Usually ~ .11c a foot avg in my area.

As a side note, the harder plastic tubing, like for fridge I've makers makes a great vacuum line if your aspirator is far from the bench. Not sure but think it is 5/16 I.D.'aa anxjnnnnn
While you are there if at an ace hardware pick up the Rooto sulfuric acid as my other local hardware store abruptly stopped selling 'liquid fire' for what I was told were 'local political reasons' e.g. meth. I am picking up two gal on tues before its an online Only item, and the Rooto doesn't have the red dye to deal with.

If you have harbor freight stores out where you live they have a small fountain pump on sale for 6 dollars. Works great. You can also check them out online.

ya I have that same harbor freight one, on sale for like 9$. cant beat the price n it's tough. but I prefer the straight from the sink adapter (for washing dishes or something) I just slide a hose clamp over it and keep a 10' leash. beats having to hunt down a socked every time you need one. then a return to the sink for waste. win win.

works great with the condenser I made for acetone a while back. ~1hr to make and dirt cheap from ace parts

though I have been curious what I would need to use for cycling a fluid other than water. caustic or super cool. most of the pumps I have seen say to keep above a certain temp and no caustic sol's. wanted to set up some cryohol (denatured alcohol n dry ice) but with the little effort I put in didn't see anything that would work. if any one has a quick answer for that I would be appreciative. if not I can get off my ass and search. just not THAT important to me. but I have been doing a fair amount of electro chem n electric solution transfer would be sweet.

hope any of that helps, though everyone else pretty much answered your questions. good luck
