Oceanrunner Or 3500

[Matthew5664]

I'm thinking of upgrading my sump pump to the Oceanrunner 3500. I can only find the Tech specs online but I need to know the dimentions of the thing. Could someone find them for me because I'm fed up with looking.

Can't really help you Matt.
Looked myself. The disturbing thing for me is not seeing any data for volume at varying head heights. This would give me pause. Also, a maximum head height of 10 ft is on the weak side for me.

The question I would have is if you are interested in a 1000 gal/hr pump, and concerned about size, how big is your sump/system?

Don't want to turn your sump into a whirlpool..hehe

At the moment I have 1700LPH return on a 2'6" head with a T back to the sump that has a trickle out of it. I was hoping to get something alittle more powerful on the return so I could had 2 outputs in the tank. At the moment I have to slowdown the flow from the tank to the sump using a ballvalve that I was hoping to get rid of. To sump is 1", return is 1/2"

System is a 40G tank with a 20G sump.

Why do you have to slow down the flow into the sump? The tank wil only overflow into the sump at the same rate that the water is pumped up (or at least should).

I have read from a number of sources that sumps need far less flow rates than tanks, and that 5x will suffice happily, and that most of the flow in the tank should com from powerheads or closed loops.

This slower flow rate apparantly helps the efficiency of skimmers in the sump as well.

I'd imagine he's doing it to reduce gurgling noise?

you can T the pump you curently have as if you do not add any additional drainage, you won't be able to add any additional flow from the return. Just spilt your current return and dial in the flow again. If you notice addition head pressure from the extra T, up the return pipe size and it should even it out again.
