1073.020 @ 4' head = ???

[Herbie]

Hi,
Just a quick question about the 1073.020. Wondering about real world gph at 4' head with 1 90 elbow. Anyone have any ideas? I am looking for about 350-400gph give or take a bit.
Also, looking for a VERY quiet pump.......will I like this one?
Thanks,
Herbie

It is at least as quiet as any of our competitors for a submersible pump. The flow at that head will be 250-300gph, you probably want to got with the 1073.040 which would be 450-500gph but you can turn it down as needed.

Thanks for the quick reply.
I think 250-300 gph may suit me fine. That will keep the flow through my sump a little slower, and I can just supplement the tank with some nano-streams.
Can I upgrade the .020 to a .040 with a impeller 1073.047 down the road if i need to?
Thanks again Roger.

No, the motor coil is not strong enough to handle the bigger impeller, it will struggle to start and eventually burn out.
