Sump Plans..

[Reefer2727]

Jim,

I have been reading the Bean thread for hours. Wow, so much info. Anyway a few questions:

If I get a return pump that is rated for 1000 gph. Taking head pressure and what not into account can I assume that I will push maybe 750 gph?

Now Bean uses a 1" bulkhead and 1.5" standpipes. (I think). What size hole is drilled for a 1" Bulkhead?

For my 75 set up....what size holes should I have them drill. There were a few people on the thread that mentioned that the 1.5" standpipe might be too big. One guy didn't even have anything coming out of his second pipe. I mean I guess it depends on the flow. Bean pushes 2000 gph. I was thinking 400 to 500 before but am thinking a little more now. Even 10x turnover for me would be 750 gph. So would my pump rated at 1000 gph be a good fit?

Any recommendations on a decent submersible return pump? I have heard the Eheim's are quiet and dont throw off too much heat.

Thanks

You might, but that depends on which pump (the flow curve of the pump)

Now Bean uses a 1" bulkhead and 1.5" standpipes. (I think). What size hole is drilled for a 1" Bulkhead?

That is what he is running. Hole size 45mm, (1.75").

See one of my posts above. The guy that had nothing out of his second pipe, probably did not have it "dialed in", or changed the design (that is an assumption, I could be wrong.) I would use a bit more pump than that.

I would be hesitant to recommend a submersible pump, because I do not use them anymore (as a return pump anyway.) If I did, I would recommend a Red Dragon, but that is way expensive. IIRC the motor is, however, a motor commonly used on several other brands of pumps, but I cannot enumerate them. Hagen comes to mind possibly.
Look for the flow curve on the pumps, and look at the wattage of the pump, less wattage for the flow you need is what you want. The lower the wattage, the less heat the pump will produce. And watch for the "wierd quirks" syndrome, as in needing 2" pipe to get any flow out of them. Eheim is a good name and been around a long time.

Not entirely true Izmadi.

See this is exactly what I am talking about! lol Practical knowledge... perhaps oddly over-tested... but usable, proven practice.

Uo6, you are exactly the spirit why this place is so valuable... :2thumbsup

Thank you, for all you do.

Jim,

I was just reading this thread and you had mentioned earlier that you would go with a 'little more pump'. Were you referring to when I said I was thinking about a pump rated for around 1000 gph?

I have been looking at the Eheim Hobby Pump 1262. Rated for 900 gph. At 5 ft head pressure the curve shows around 750 gph. Seems pretty good to me. I was initially planning less flow but with Beans design and those 1.75" holes. I think I may need a little more flow. Not sure.

 

[uncleof6]

Yes. (I would bump it to 1500 rated). Eheim is a good name. And if you can keep it to 5 ft head pressure, according to the flow curve 5 times your total volume, with some head room for your fuge, should be fine. Remember, those 1.75" holes, will have a 1" bulkhead. At this point you should go directly to the source: BeanAnimal, he knows this system better than anyone else. I believe if my info was bad, he would have already been here; my system has worked fine w/no issues. But to be thorough, run it past Bean.

Regards,

Jim

Sorry for misspelling your name there, just that Izmadi flows better than Imzadi

Wow. That is much more flow than I had planned for. I will check in with Bean. He says it works well for lower flow set ups.

Well see.

I agree that it will work well for lower flow setups, I am saying I I I would bump it to 1500.

Im not sure that I need that much flow. Its getting very expensive too. Lol.

This set up must be tight when trying to feed three pipes into the skimmer intake zone in the sump. Although, I guess the emergency drain could be piped anywhere into the sump. Return area may be best I presume.

Another problem I see is being able to get at all the plumbing. My set up will be against a wall and I can't imagine having much room to do anything behind it.

This project has definitely consumed me though.

You don't need it, it is nice to have-- and if you read my post above you know one good reason.

If you are clever, you can fit this system in under 5" from the wall, the valves you need can be down where you can reach them from underneath. And the drain lines can be cleaned from above (the top cap is removable. Not to be a doomsayer or anything, but if your plumbing breaks you are sorta screwed anyway. But most people can reach at about 6", and keeping the plumbing towards the ends, not in the middle.
