Plumbing question

Right now I am dropping water lines from my aquarium sump to the basement below it into a pump which pushes the water through my chiller and then back into the tank. This is all in my shop, which is sometimes dusty. I have filters and doors on the chiller cabinet, but when closed, the chiller gets pretty warm so unless I am doing woodworking, it is open. I have a store room in the basement that is approximately twenty feet away from the chiller/pump. I would have to run over ten feet and then across 20 feet and make my drop to set up a refugium, skimmer etc. station in that room. That room has a drain, sink electricity, etc. Do you see any problems in this idea? I think a bigger pump would probably be in order, and probably some check valves (probably should have these anyway), but anything else? My lift would only increase by about three feet.
 
Right now the pump is an Iwaki WMD-30RLXT which is rated at 960 gph. Any idea how much bigger I would want to go?
 
With all that head you're not getting much out of that iwaki. I'm surprised it's pumping anything at all. Sounds like you need to go much bigger, like an ampmaster 3000 or a large sequnce pump. Remember, horizontal footage also causes resistance to flow... Any bends and elbows also add to your resistance. What kind of flow are you looking to end up with all said and done? Use this and then calculate your estimated "head feet" including all your bends, horizontal distance, etc... I think there's a calculator somewhere... Then find a pump that will put out your desired flow with the amount of head you are estimating.

HTH
 
The head loss calculator is on the home page, left hand side, 1/2 way down.... there is a little section called "calculators" and the first one is the head loss calculator. Try it out!!
 
Thanks. I guess there's a lot of information here that I hadn't realized was here. Now to see if I can understand it.
