Check this one out. It looks quite similar to the STS pump and has a good price.

Tell them Sean S told you about it.

Thanks

are you affiliated with this company or what?

 

No, just sharing some useful info.

 

just wondering, looks like it could be usefull for some one off applications though.

 

"Max working temperature 140F". Err, no, I think not. All who also think the oil coming off a turbo center section is likely to be at a consistently much higher temperature than that raise hands. Consider that our engines' WATER temperatures run around 190F, watercooled turbo or not.
A nice thought though.

 

about the only pump that will work for that application is a pre-luber. they are designed specifically for engine oil and turbo lubrication.

 

This is why most serious turbocharger folks use multi-stage dry sump systems - one or two stages for the engine, another for the turbos.

Doesn't matter what pump you use (for turbos) as long as you can get at least 15psi out of it and it's a gear type pump made of materials capable of handling 400-450 degrees. The oil coming out of the turbos is much hotter than the air that flows through it, because the oil is closer to the exhaust turbine than the freshly compressed air.

Meshed gears or georotor is fine.
