OC20 v OC50 Invert

Postby Bones » Tue Jan 19, 2010 6:31 pm

Hi all,

Has anyone purchased the Invert model centrifuge, if so how does it compare to the standard OC20?

Seems to be one of the highest in terms of 'G' force or is this unnecessary?

I have some stats from our UK supplier here and wondered if it was worth paying the extra £100 for.

TIA

Higher G is always better. Whether its worth the money depends solely on how many gallons per month you use and how much time it may save, it has 20% more G force, so should clean 20% faster. Double the flow rate should make it almost double the cleaning speed. Also the motor and pump you buy will probably cost more.

I only run mine a few times a month (80 gallons per month) so it matters little to me if I come back after 4 hours and its done, versus 2 hours.

Thanks SunWizard,

I liked the idea of the sealed rotor which catches the water and holds it even after shutdown, it also looks a lot more robust and balanced.

The package comes with a Performance - Viscomat Gear 200/2 pump but is only rated to 55 Celsius, seems a bit low?

Any thoughts on the combo?

Yes thats much too low. That makes me wonder how much experience they have with CF.

I would need to see flow at various pressures to compare. I wouldn't buy direct from china.

Thanks, it was on Ebay and looked as though there was no interest it it or at least until I put my bid in :wink:

I'll keep looking, one will turn up - I had thought about a power steering pump but the Neon ones are quite expensive.

Apologies if this has been answered before (haven't finished the info pop thread yet).

Would it be possible to use one of these Chevy oil pumps with a washing machine motor?

Any idea size of pulleys?

A few have used V8 chevy pumps which are probably better than that one. They have reported lots of leaking around the shaft at high pressure, and have a hard time getting to 90psi. They are designed for higher flow and lower pressure than we need.

I wondered about the oil pump idea as this was the original power source.

Just noticed they fit them as standard on some Land Rovers

Struggling here on the pump front, this is for water but with a brass impeller I wondered if it would be ok for wvo

It's rated at 109psi although thats bound to drop off using veg.

I would need to see flow at various pressures to compare. They both look bad, and whatever they are rated for water will drop drastically, by about 50% on VO.
