Rio 20HF Vs Resun MD55

[Kenji80]

Anyone tried the above 2 pumps on a same system?

Can give some comments?

Thanks.

rio 20hf has high flowrate, but certainly doesn't have the strenght to push as far as md55...

if your return pipe is very long, u might wanna use md55...but if it is somewhere like 3-4ft, then just use 20hf...

to use 20hf, i believe your overflow needs to be at least 1 1/4" pipings...for md55, at least 2 X 1" or 1 X 1 1/2" pipings...
