1 pump vs 2 pumps = flow output ??

[Ditryin]

Hi all!!

I have a 40w UV that requires 1930 - 2900 gph for bacteria. I bought a Nautilus dc 3200 pump for it and after 6 months it died. I bought another one [admittedly not my smartest move] and it died after 3-1/2 months. So I just bought **another** $300 pump (MaxSpect Jump) and then I wondered...

Instead of of using one, big, heavy, expensive pump to get the gallons per hour I need, could I use 2 smaller pumps, hooked them to a Y and both feed into the UV together to get the flow I need? I understand that I'll have some head pressure loss.

So if I have two 1250 gph pumps, for example, hooked to a Y, would that get me 2000+ gph thru the uv?

Thanks!!!

I think you can have 2 pumps feed the same line but you would want one way valves after each pump before the Y.

Is this a huge tank? What’s the drawback to just using the one slower pump?

To save on space this may help:

Never used them so I don’t have first hand experience.
All I remember is looking at them and thinking that is interesting.
