Re: [Biofuel] mixing and heating biodiesel

[Mike Weaver]

Some people have had luck looking on www.pumpbiz.com

I use an old drill and a long, bent rod like a paint stirrer. Works
great for 20 gallons or so - all you need is a vortex on the surface.

Stainless will work for immersion. I use quite a bit of steel and have
yet to have a problem.

Good luck,

Mike

want to use a pump to mix. What type and size of pump would be suitable
for 15-20 gallon batch. Does it have to be resistant to methanol and
lye mix as well as fry oil? Also when using an immersion heater for
the heat source is is critical that it also be resistant ie; stainlesss
or can a steel unit withstand the mix for a long time before needing
replacement?

As for the pump harbor freight has a 1
clear water pump $37.00 aprox also available on line I use one for 120 liters
no problem as of yet and at the price you cant go wrong. 

Immersion heater stainless steel would be
good but I work to hard to pay so much for that so I use a standerd 240 volt
unit with 110 v supply. Works good. Dont let it go dry.

Good luck Derick
