Re: [Biofuel] Pump choice
Sorry I am so tardy. Yup with no measurable crap I also do the reprocessing technique form time to time with no added glycerol. But I do let the mix set for a minimum of 24 to 36 hours. I have found that after draining off the glycerol under 24 hours I let it sit for a few more hours and low and behold there is more glycerol. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joe Street Sent: Friday, July 21, 2006 6:00 AM To: biofuel@sustainablelists.org Subject: Re: [Biofuel] Pump choice Hi Derick; Just out of curiosity do you do the methanol test after you make your fuel and if so how are your reaction percentages?

[Biofuel] Pump choice-quality fuel
BTW for doing quality tests one of these is very handy: http://canadawide.ca/products/264-100.1.html I have modified the volumes from those on J2F, which called for the volume of 25 ml BD to 225 ml methanol, to fit this tube. In this case use 10 ml BD to 90 ml MEOH and then every 1 ml equals 10% unreacted stuff. The tube is graduated down to 0.05 ml at the bottom though so you can accurately measure 1/2 a percent. You'll be able to tell for sure if your processor is really working for those 120 litre batches.

Hey Mike; I'd like to add that the solvent in some of these pipe dope products is not compatible with some plastics so if you are using any plastic fittings look for pipe dope that specifically says for metal and plastic.

Re: [Biofuel] Pump choice
Mike, The label says "Rectorseal". I think that's the company that makes it. There's a 5 inside a red circle. It says Slow Dry on the left of the 5 and Soft Set on the right. Pipe Thread Sealant is written under the 5. I bought a 4 oz can at Lowe's. Any brush-on pipe dope might work, but this doesn't harden and was recommended for fittings in fuel lines.

Re: [Biofuel] Pump choice
Hi Mike; I can only speak from my own experience and I haven't used that combination but I have read a fer anecdotes. Sorry but I think you should not get too excited about 40 gallons. You may find that you can only fill that tank to the 25 gallon point with that size plumbing and pump. You would not be the first one to discover this! There is no fine print telling you this by the people selling kits with a 40 gallon tank and clear pump. But then again if you don't do quality tests you would never know.

Re: [Biofuel] Pump choice
Charles, As Mikw Weaver pointed out, 1" Clearwater pumps are not self-priming. Another way to avoid priming each time is to: Position the pump so that it is level with the bottom of the WVO source and the bottom of the reactor. This allows it to prime by gravity. I pump WVO from a plastic barrel that is on a small platform ~ 16 inches high. My pump and reactor are on platforms the same height. I used JB Weld to attach a plastic nipple about 2 inches from the bottom of the WVO barrel > line to the pump. Air leaks do impair the pump's ability. I'd recommend threaded barbs w. hose clamps for any hoses ... (rather than using pipe nipples to hoses). Also check on a regular basis to make sure clamps are tight. While teflon tape works great for water lines, it is not recommended for fuel/solvents lines. The fittings will eventually leak and the tape turns to goo. I was advised to use a slow dry, soft set, pipe thread sealant when plumbing fittings in my reactor. After 8 months, no leaks. The fittings are also very easy to disassemble for processor maintenance.

Re: [Biofuel] Pump choice
Hey Tom; My guess on this is it is not so much the pump but the size of the plumbing. I noticed that one particular pump with the same size motor and impeller was offered with 1" or 3/4" inlet and the throughput was almost the same as a smaller pump with standard 3/4" inlet unless you ordered it with the 1" I then took a look at a whoile bunch of pump curves and what you find is that you won't get beyond about 10-15 GPM with any size motor or pump unless you go larger than 3/4" on the pump inlet. The 90 litre wall I think is related to the 3/4" tank connections on the hot water tanks we all like using not the pump per se but it amounts to the same difference in the end. I believe it is a waste of time and money buying a larger tank than about 100 litres since as most people find out you can't get a good reaction on about more than 90 litres of oil anyways.

Re: [Biofuel] Pump choice
We're using a clearwater with good results - but be careful to leave a little oil in it for priming purposes and when you plumb it use tape - any air leaks really impair its ability...

Re: [Biofuel] Pump choice
Charles, The impeller in the clearwater pump is metal. Plastic impellers will eventually fail in pumps used to agitate the reaction. My experience w. the clearwater pump is that it will handle up to 90L (~ 24 gal) batches. Above that, even after three hours reaction time, I have gotten incomplete reactions. Congratulations on your success scaling up.

[Biofuel] Pump choice
Hi All Thanks to all who have advised me this last few months, I am now a biofueller! 105l batches, good product. Unfortunately, after 10 good batches, my pump has started spraying out of the back of the impeller housing. So I took it apart and the impeller has broken up and the housing has been eaten through at the back, around the mechanical seal. It was 30 years old or so, free and a plastic spa pump, so I'm not too distressed, but I obviously don't want it happening again. I notice that the clearwater pump used by JtF is made of cast iron, so should my next pump be made of metal? Also, is the impeller in the clearwater pump plastic? As I know you can get some with stainless steel blades, I wonder my impeller break-up was due to age or chemicals.
