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.

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? What is your process 
temperature and how long do you react?

I've heard teflon can be bad for your health. Especially when smoked.
I don't think they have the same effect anyways.

Re: [Biofuel] Pump choice

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.  It is available in most hardware stores.

The contractors that work for me always swear by 'pro dope' and they 
always seem to be laughing and having a merry old time whenever I come 
on the jobsite. FWIW.

No problem I have been making 120 liter batches for 2 years with not one

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

Re: [Biofuel] Pump choice

[Thomas Kelly]

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

[Joe Street]

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.

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.

Thanks

Charles List

Any advice on 40 gallon batches and a clearwater pump?  We haven't used 
this latest reactor yet - will it have enought power to
mix 40 gallons?

Joe,
 I'll sure you're right. I am using 3/4" fittings. Going to 1" fittings 
and lines would allow one to break the 90L barrier.

Re: [Biofuel] Pump choice

[Thomas Kelly]

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.
 Best of luck,
 Tom

Re: [Biofuel] Pump choice

[Joe Street]

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.

Joe

Sorry, I was being cheeky, they'll work until the methoxide eats them - 
of course - I was using an old Dodge pump so YMMV.

Re: [Biofuel] Pump choice

[Mike Weaver]

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

[Thomas Kelly]

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.

 Tom

I think it'll work, Michael Allen was using them in Thailand for 
things biodiesel and didn't have problems.

  Uhh, how can the answer to both questions be yes.  If it 
  dissolves, it won't work, right?I'd think it shouldn't have a problem 
  with methanol, since that's in windshield washer fluid anyway, but methoxide 
  is a different monster.  Plus, these pumps are pretty chinzy -- I think 
  they'd burn out after not too long of continuous operation even with the 
  nicest fluid.  In a 20 year lifetime of a car, it would only run about 60 
  hours (assumptions: 200,000 miles, 10% of miles require using windshield 
  washers, when using it it is used 3 times per mile, for three 1 second shots

Re: [Biofuel] Pump choice

[Zeke Yewdall]

Uhh, how can the answer to both questions be yes.  If it dissolves, it won't work, right?I'd think it shouldn't have a problem with methanol, since that's in windshield washer fluid anyway, but methoxide is a different monster.  Plus, these pumps are pretty chinzy -- I think they'd burn out after not too long of continuous operation even with the nicest fluid.  In a 20 year lifetime of a car, it would only run about 60 hours (assumptions: 200,000 miles, 10% of miles require using windshield washers, when using it it is used 3 times per mile, for three 1 second shots each time)

i have a pump question on a side note. will a window washer fluid pump from 
a car work in my little test reactor, or will it dissolve as well?
