WVO Transfer Pump

[nathanrobo]

WVO Designs have what looks like a pretty capable gear pump for transferring WVO from the restaurant to your vehicle:

The suggestion is that it can cope with unfiltered oil.  I spoke to my gear pump manufacturer and they recon that even with helical gears, the oil should have some filtration.  Opinions please!!  I'm planning fetch a pump in and give it a trial - It will be interesting to hear whether is struggles with thick, unfiltered oil.

Im thinking that is a "how long is a bit of string" question...

If the wvo is contaminated with dusty bcbs, then itll, i suspect, be fine, but, if its contaminated with dead mice, full size blackened chips, snails, kitchen cutlery, etc.etc. then i dont think it would be.


You could fit a foot strainer, but then they just get blocked.

I have a mono, and have considered using it to unload the car, but i dont even think it would work well there.


I guess if you have some sort of setup where the input pipe *cant* get close to the bottom of the drum, that would be a partial solution?

Looks like a capable pump, but in their videos they look to be pomping pretty clean oil.

By it's design I'd have thought a gear pump wouldn't be happy chomping away at BCBs.

They are a lot more expensive and probably not as quick, but I think a Mono pump would be better suited to the duty.  As their generic name ... "progressive cavity" implies they sort of take gulps of fluid and pass it along ... bitlike an archmedian screw.

I unwittingly transferred a crane fly out of my settling tank using my Mono.  It got stuck in a clear bodied filter and so was visible.  In travelling through the pump it only lost a wing and one leg!

but did it survive julian?

Nothing survives a "Julian"

Wasn't she female?  On second thoughts, don't answer that.

Mate would you be expecting to run an extension lead out of the restaurant to the dark depths of the alleyway to run it ?

not sure not a snake person, think there wedding tackle is too far down its head to see, wonder if all of them were one sex?

hmmm

wow crikey nice price tag

the ol shaft looks slightly chewed up to me? for a brand new part/picture need a lathe person to clarify...

[Rotary-Motion]

hmmm just read then spec

-will not work well with motor oil.  New 1750RPM motor coming for motor oil use.   ETA 2/15/2013

perhaaps motor oil is too thin for it??? odd.

Hmm,

Think i'll stick to the original idea.  Heat, pass through strainer via gravity.

HOW MUCH!!!???

Looking at the rotors, it looks very much to me like the same principle as a hydraulic pump off a digger. If it is, it would rip your fingers off, spit them out without changing its speed, and then start on the rest of your hand.
So long as it doesn't hit metal.

Just an idea thats occurred to me. What about try to put a motor on a hydraulic pump off a digger. I would say, even a shot hydraulic pump would still have enough go in it to pump thick gloopy WVO. Maybe try and find a shot one off, say, a two tonne or less mini digger. Anything bigger might need to big a motor to drive it. There should be plenty about, they wear out all the time.
The price of it is coming in at Hydraulic pump prices.

I can't quite fathom that out. It seems as though they relate the speed of the motor to the fact that it is not so good with engine oil, but I can't see what speed this one turns at.
A hydraulic pump would turn at engine speed, so around 3500RPM. If this one is going at that speed, then maybe somehow it struggles to "catch" the oil, and flicks it away instead, which a slower motor would not do.

Like the sound of that!
