for starters, a perspective on pumps perhaps
as you probably know, Swiftech initially sold (introduced to WCing in fact) Eheim pumps, then Siccie, now the 'unidentified mfgr' pump; so we have a pretty fair understanding of how pumps fail, and how long it takes, blah blah
there is a distribution involved, but 'better' products will begin failing later than 'lesser' pumps; but they will all fail eventually (though some will outlive us)
in addition to the above experience, I have an ongoing test program to identify possible new products
- I can assure you that new products have a higher failure rate simply due to the time required to debug a process, establish process controls based on the process characteristics as they become known, and setup an effective QC system to monitor the process
- I have spoken to many pump mfgrs about a 50,000 hr MTBF, and we have a laugh and then discuss the difficulties
do you know of any aquarium pump with a 50,000 hr MTBF ?
do you know of any 'industrial' pump (in the WCing size range) with a 50,000 hr MTBF ?
so did it not occur to you that: 1) this pump is VERY special - if so, why ?
or 2) this claim is bogus ?
(as a reviewer I suggest initial skepticism always)
I suggest you ask the mfgr for the data to support the 50,000 hr MTBF assertion
-> because if they do not have such they can have legal difficulties (in the US)
we await your adding the missing piece
