shadrach74 - there seem to be pro's and con's to each scenario when you look at failures and how they happen etc. Since GEBA just started running this pump since late last year, I thought i'd send them a message to see what they had to say about this 'new' metal impeller setup and how it fairs against the dreaded 'engine case destroyer scenario'. (I like their products because they make awesome pumps for VW and BMW) anyhow... I got a very quick and kind reply from the production manager in Germany.... (which I will translate to short here)
"We started production of the new pump 15007 at the end of 2012 and decided to utilize a metal Impeller because of the known Problems with the plastic ones. We also decided to utilize for these pumps the original bearing which Porsche is using for their production series which features an added Roller Bearing design which will reduce radial and axial play to a minimum." Also the distance between the pulley and Pump housing are extremely small, so if bearing failure would occur the Impeller could not move significantly into any direction"
Looking at this new pump, I like it; its not cheap, but equally priced to the LASO pump which seem to have its own set of issues at times.
Anyhow, I like trying new things especially when its new and revised - technically it should be better
