1 Pump for Return and Closed Loop? Reeflo Dart

[familiar1985]

would it be possible to make a Reeflo Dart pump 1000 gph from sump and 2000+from Main to release 3000+ into Main. I really like this idea and was hoping that there is a good way to do it.
This way i can have 1 pump handling all the water movement and not use up to much electricity, yet still give me some nice random waves through a SCWD

I'm a little lost here. Are you saying, "can you use two pumps in tandem to produce 3000 gph flow"? If so, yes you can if you have the plumping sized to handle it or use two individual sets of pipes to feed the tank. The smaller pump in such a case, using the same plumbing, must have a higher discharge head pressure than the larger, or it will fail to work. Separate lines are always a better choice if running two different pumps

i meant using only 1 pump for both. external pump sucks water from main and sump and spits it all in main. Cant i split the intake of the pump. Im just not sure of how i would make sure that that a high flow pump like that isnt sucking more then 1000gph out of my sump. Maybe with some kind of regulator. Any suggestions?

Ok, I getting the picture now. No, it doesn't work that way. If you have two tanks on different levels the tank closest to the pump wins. All the flow will be from the area of least head; meaning the tank that is closest to the discharge of the pump. Only if both intakes and discharges are exactly equal can you do that and, even then, it will cause problems over time. Use two pumps and save yourself some headaches.

Nope, if it's open to the sump it's not a true closed loop anyways and there are many logistical issues with keeping the display from draining down when the pump is shut off.
