Hercules MBTF

Question

I have just ordered my first custom loop with a CR120 reservior combo and a hercules (V2??) pump inside and very satisified how well it performed. however I just found that industry standard like the D5 pump is rated for 50k+ hours of MBTF and the hercules and other bitspower pumps are only rated at less than 1/3 at 15k hours, which equates to only 1.7 years of 24/7 use. May I ask if that's just bitspower's rating varification process only tops out at 15k hours or it is indeed designed to last that much less than a D5?

Answer 1

Dear YSC,

Sorry for the confusion.
The MTBF for the Hercules pump is  ≥ 15,000 hours.
We missed the ≥ symbol. It can operate for over 5 years.
Our Titan series K1M pump also has an MTBF of ≥15,000 hours.
Many customers have used it for more than 5 years.

Thanks for the response, if so it seems BitsPower only do validation until the 15,000 hours mark and thus the marking of ≥ 15,000 hours. I was just confused and since there isn't much discussion on internet and indeed I saw some discussion of ppl opt for a D5 just because of the significantly lower rated number and another post saying his pump died just after 6 months of use with DP ultra fluid with the ceremic bearing worn off.

It seems like it will be a good idea for your great products to do stress testing near the 50,000 hours as rated in the so typical D5 pumps if possible would be more clear and gives confidence as the  ≥ 15,000 hours could imply the MTBF is around that mark only.
