Thats good to know. I didn't realize anyone had been using one for VO filtration that long yet...

I also agree that PV does not = polymerization, but it is a pre-cursor for it. Also, I know of no one who has blamed the CF for a problem.

I directed someone to this thread and decided to re-read it when I did. Thats when I made the connection between the 'bleached' VO and PV levels.

Thanks again Sun, keep up the good work!

Concerning when to shut off one of the heater elements, where and how are you taking the VO temperature reading, in the barrel or at the inline heater?

Thanks

With an IR thermometer on the pipe just before it enters the CF.

I found a pump/motor on Craigslist and was wondering if the pump fits the bill.

I can't find info on the pump, but the seller tells me it is an Oberdorfer model 500 2A. Already coupled to a 1/3HP motor.

My head spins trying to find things again on the Infopop thread...sorry if I'm missing an easy search item...but will this pump work?

You would need to go to oberdorfer's website and see if you can find the specs. It might not be a gear pump, they also make centrifugal pumps that would not work.

Well I searched their site, but can't find the model # the seller gave me. Not sure if he got it right...

the ad is here:
http://madison.craigslist.org/tls/64568466.html

It sure looks like a gear pump and I guess I was wondering if any Oberdorfer gear pump will work, or if the odds are that this one might not be right?

Yes its a gear pump, it looks like an old one, and about the right size. I would get it, nice price. Its so good you might want to remove the link from your post so no one else grabs it first.

Sunwizard -
Nice little place you got here!
Trying to make an inline heater like you made. I went to lowes the other day and tried threading a water heater element into a 1 inch iron pipe T. the first 1 or 2 threads grabbed but after that I could not turn it by hand. Almost felt like it was a different thread? Or is it just tight and I need wrenches to screw it in?

How did you do this on your setup? What do i need to make it work?

It is slightly different thread. All you need is wrenches and an oring seal like I describe on page 1 of this thread.

Dieselcraft up to $399!? (Edit: $299 --oops!)

Postby wvoalaska » Wed Apr 30, 2008 3:44 pm

Holy crap! I was just starting to think again about getting a dieselcraft centrifuge and it looks like they have raised their rates quite a bit since the last time I looked: http://www.dieselcraft.com/productinfo_OCForum.html

Supply and demand? Cost of production and materials? Lower value of the greenback? All three?

Does anyone know if one can be obtained any (like maybe 70 bucks) cheaper? I didn't get one before because it was prohibitvely expensive and that was when they were $215 shipped!

!

Yes to those 3. And they are the same price from all sources now that dealers sell them, the higher price gives the dealer some profits. It also includes: the rotor is now nickel plated, and 2 tees, 2 hose barbs, pressure guage, and a ball valve.

No difference. Its best to not get galvanized.

Re: Mobile "Holy Grail" version of this rig

I made a mobile unit out of this same rig, to use when I am travelling long distances so I don't have to carry hundreds of gallons of Veg. Oil. I run it with a little, quiet honda 2000watt generator, or plugin power if I am stopped where I have it. I mounted this same rig on a closed top barrel, and put a 3 way ball valve in the pipe from the CF output to the barrel, and switch it at shutdown into a small jar to capture any water and goo that comes out.


I actually considered doing this before I found this post where you have already done it. What stopped me is my concern that a small cheap genset wouldn't have enough watts to both heat my WVO and spin the CF pump at the same time.

So is your 2000 watts enough?

Yes for the 1125w element and 500w pump. I don't run both elements so it is slower heat in the first hour.
