I have numerous KEDSUM submersible pumps running in & out door ponds. They are very reliable with fresh water temperature varies from 10C to 28C (koi, goldfish to arowana). Since KEDSUM makes various size & throughput, for those who wants to compare apple to apple. Look at the GPH/$ and GPH/watt, the 880 GPH pump only consumes 65-70 watts btw and the entire pump family GPH/watt is 13-14. This is very competitive among all the submersible pump out there. I am using those pumps for mechanical/bio filter throughput with no more than 36" of lift, so I can't confirm about their head claim capability. But I don't doubt these are very capable pumps for the $$$.
