My experience with China made pump is that they're not so reliable.
Used to run 3 Jebao pumps(FM 3500,6500&10000 total 160w)
All died within a year.
Now replaced with a Fluval Sea SP6(12300 LPH 100w)tee off to return,chiller&skimmer.
Now less heat from all the pumps and my chiller run less often.
So overall lower power consumption.
