Well not many posts so I guess I will try to keep some momentum alive. Been a tough week, I blew an o ring on a filter while testing and managed to spill 4 galls or so of wmo, what a mess. My pump does not want to flow wmo at 35 deg and is not giving me the flow I need for the fuge so I have to rip apart my setup and redo with a bigger pump. Tried heating the oil but the pump is spinning too fast (direct drive) to pull oil reliably. I have an old cessna pump that I may try to use. I am concerned my woodpile is shrinking faster than the winter and I cannot go into the woods right now.
I did try to use a small 1000w tank coolant heater in my return line for some limited testing, zero start and it works just fine thank you, so I will file that away for later. Shop is a mess and I oiled my clothes head to toe and sprayed oil on the walls, ceiling , floor, etc. I think in the spring I will move my ops to a small trailer on site so if I make a mess it will not be in the shop. Anyway, c'mon guys, post away tell us what you are doing, what works and does not for you.

I am curious about what others might be using for a centrifuge pump. I have an OC 50. My old pump is too large, it cavitates and when I slow it down cannot get enough pressure and flow, the small pump cavitates and wont make enough flow. I am in the testing phase only and my oil is around 100F. No money because of layoff so my options are very limited. I know some use a sbc pump, but I have no access I have this
.http://www.princessauto.com/pal/en/Pumps/32-GPM-Hydraulic-Gear-Pump/8375354.pcess. I have this motor that i assume I can make into a pump. I have one of these http://www.princessauto.com/pal/en/Pumps/32-GPM-Hydraulic-Gear-Pump/8375354.p
but it has not performed, it cavitates at 3500 rpm and does not get pressure high enuff at 1750. Anyway, what are you guys using?

Hey I hear ya on the mess that oil can make. I ended up with about that same amount on my garage floor. Wow, what a mess. All I can say is floor dry is a life saver.
No centrifuge here so I cant comment on that. Good luck in your endeavor.

I am using sawdust which is mdf/particleboard for a floor dry and it works pretty good and I can sweep it up and burn it too boot!
I am Trying to do it now as I work all thru the summer (rv tech) so now is when I have free time.
The zero start tank heater has been a suprise it worked so well. I am only heating small test batch as the main batch will be heated with the oil fired water heater later. I would like to prepare at least 150 galls before winter is over for long term storage.
I noticed on another site that the guy was using a 1.98 ci hydro pump, that is huge compared to what I have, but I know some guys use a harbour freight water pump with some success, my local princess auto really has nothing like that. I need 100 psi at 1 gpm minimum and be consistent.
Anyway looks like the weather is turning cold again. I will make some more sawdust logs using the sawdust and bottoms of wmo jugs and pack large cardboard tubes. Lasts several hours, good heat, no smoke. I pack them good then leave a hole down the center to get a good burn.
I am thinking of relocating to an old trailer I have so as not to mess up the shop, will look at that this summer.
My mix at this time for the shop is 25% rug to wmo or wvo (nice canola oil). Pump on the Beckett is about 150 psi with a .75 nozzel. Flame fills the pot and I have a small piece of steel in the pot to absorb heat tand help with combustion. Using just a standard general felt filter. WVO is filtered once thru a fabric shopping bag filter after settling. My wmo is filtered once thru a maple syrup sock bag filter. No plugging of nozzel in 2.5 years.
Take care all and post!
