Do pipe size affect the flow and can it damage the pump

[anum]

Hi,

Got a question. I got a rio20 for my return pump, I know what Qmax is but if my pipe size is only 13mm where else the outlet OD is 21mm will it affect the pump, such as overheating or reduce lifespan?

Very unlikely to overheat the pump but it will reduce the efficiency of the pump. 20HF is not a pressure rated pump and is best installed with the max diameter pipe allowed.

Pipe diameter is just like a road, the wider the road the cars can speed faster and vise versa. But if u have pressure control valve, no matter what flow rate, u can still maintain ur desired pressure!

Thanks gurus. Looks like I have to change my pipings b4 installing the rio20.
