Choosing a pump for my basement sump system.
DT: 105G
Head: 9.5'
For the return flow I'd like to have somewhere between 600gph. Will also use the pump to drive GFO and Carbon. But with minimum head and low flow rate, these reactors should draw very little from the pump.
I have just obtained a used Reef Octopus 10500 DC pump. Tested it out using the bucket method I get ~650gph @11'. ~600gph @12'. With 2 90 degree elbows and 1' PVC.
This flow rate should be fine for my use. However I can concerned with longevity. I know the DC 10500 is not a pressure rated pump but will the high head pressure reduce the life span of the pump? I really love this pump, dead silent and slow start etc ...
Other choice: Reeflo Dart: 1150gph @10', 650 @12'. Why the huge drop off? With elbows etc the actually flow rate might be even lower than the DC10500.
Iwaki 55RLT: about 900gph @10' head.
What's your opinion on the DC pump and any suggestions for pump choice?
