WVO Processor ver. 2.0

For my first setup to see if it would work, I used a carbonator pump (used in soda fountain machines) like this one.  They work, but over time (hundreds of gallons for me) the procon vane pumps clog with polymerized VO.

The centrifuge I use is this:

However I did also make a second setup using a centrifuge like this that seemed to work just as well.

I heard that some Chevy small block gear pumps work really well. (Never tried it).

The price ranges are getting into my budgetary allocation range.  But I'm still confused.  Surprise!

These in-line centrifuges still need a pump to supply the oil?

And bschwartz, you're saying that the $60 pump on Ebay can do that?  It has it's own on-board motor?

The Chevy pump is what first came to my mind.

I can say from experiance that a Retired (Used) big block chevy oil pump can produce in excess of 150psi
with the internal regulator bypassed. But I do not know how many GPM it produced because It did not matter for what I used it for... It did have some leaks (seepage) but that did not matter as I used in a bucket. I set mine up in a 5 gallon bucket with the motor on top. it worked very well! unfortunetly I do not remember what HP motor it was... I'd guess 1/2hp or so.

I do know that if you capped the outlet (Closed the Valve) it would stop the motor dead! (Remember the
bypass valve was blocked)

Sorry if this is a useless rambling.

Casey,

The one on ebay (carbonator pump) is usually a 1/3 hp electric motor with a procon style vane pump.  The pump is detachable and looks like this:

The centrifuge is powered by the pressurized oil.
The oil enters the centrifuge, and is squirted out (inside the domed cover) of the rotor in opposite directions, causing the rotor to spin.

Different brand, but basically the same

does this help?

Here's a fellow who uses a small block Chevy oil pump on a dieselcraft centrifuge....

Nope.... Not something I'd consider for a minute.
I manage PLENTY of spills without building a system around a pump that has no seal designed to keep the oil in.
There are plenty of other cheap options including power steering pumps etc.

Well I'm pretty dizzy but I can see a pipe fitting for a screw in water heater element is my next purchase.  I'll braze it right there towards the bottom of my tank which is designed for  20 gallon batches.  As a 60 year member of Rocky Jones Space Rangers I think a thermostat is absolutely mandatory.

bschwartz's pump looks really nice and did you notice they'll set the bypass to your specs.  I'll get a photo of my filter tomorrow for your review and see if I'm barking up the right tree.

Whatever pump you use, make sure you have a relieve valve in the system which bypasses back to the tank.
All the pumps we have been discussing are positive displacement types and need some sort of pressure relief in case the discharge gets blocked ( forgetting to open a valve ) or the output is higher than the centrifuge can accept.

Some pumps have a built-in RV....which is a nice benefit.

I have a Spinner II Model 76SE.  Photos below.  Looks great - I think?

Is this what I need? 

http://www.spinnerii.com/files/comm_id_30/Lo76SEservice.pdf

The air port on the bottom?  I wonder how many CFM this thing uses?  So let's see.  About 1000 watts for the water heater element.  About 400 watts for the pump.  About 100 watts for the vent fan.  That's 1500 watts or 60 cents an hour in Hawaii.  And now 15 Amps - 240 Volts for an air compressor.  This thing better have some very, and I mean very, fine snot coming out after a couple of hours.

Comments?

Per the PDF document from your centrifuge....:

Air pressure can vary from 35 to 125 psig. No regulators, vales or control devices are required. The Spinner II
control automatically shuts off the air supply when the
engine stops. 0.02 SCFM air consumption is almost too
small to measure

Yes, the stuff coming out after a few hours of running will be too fine to feel the texture.  It will remove particles down below 1 micron.

Assuming you run yours as long as I run mine for a 45 gallon batch (24 hours), which I DOUBT you will.
I like overkill....  $0.60 per hour x 24 = $14.40.  This is if your heater NEVER turned off which it will once it gets to temperature.  It will cycle on and off to maintain your target (mine is set to ~190F).

$14.40 for 45 gallons of fuel works out to $0.32 per gallon.  Still not bad even if you pay through the nose for electricity.

Alright guys this is a good deal...continuous motor and oberdorfer pump...secret, make offer of $225 is yours....5 left

That IS a good price, and that is EXACTLY the type of pump arrangement to use!!!
Good find Shipo!!

Nice little pumps, and a very good price.

Beware....these are noisy little buggers. At first you will thing something is broken.
