Is My Math Right? 22ft Vertical Lift?

[DocPorkChop]

I am starting to do the research on what type of pump to get for my system and just want to get some expert opinions to double check my math. I am going to have a sump (50gal) in my basement with the display tank (54gal) in an above ground room that does not have any of the basement underneath it. Because of this I am going to have to have some longer than normal plumbing

Total Vertical = 11 feet 3 inches
Total Horizontal = 30 feet
90 Degree Bends = 8

Total Lift Required 22 feet

I’ve been looking at the pumps at BRS and it seems like an external pump like the Iwaki 55RT or the Varios 10 will be required to get about 500-600gph. Without going over $1000 are there any other pumps that could provide that output with that lift? Also I assume the Power Usage wattage displayed on BRS is per hour?

Iwaki or panworld You will want iwaki 70 or 100 equivalent

lg makes some nice pumps too

Whatever you think you need get 2 sizes up and a gate valve. If you come up short you are stuck with $1000 pump that you will get $500 for on the marketplace. If you are concerned with wattage, get a DC and skip the gate valve. I have 1000gph with a 5' lift and I max out at 450ghp with 3x 90s. Consider UV in the future as well that will dig in 25%.

Go up in plumbing size to minimize the friction loss in your pipe and fittings

I was planning to go with 1” pipe, are you saying make that bigger like 1.5”?

From looking at the Iwaki 70 RT specs it should provide about 720 gph at 24 feet. That would be enough right?

Only reason I’m asking about the wattage is to keep track of the total power for the build

Play with a calculator and see what that can do for you. If you can slow the velocity down the friction loss goes way down

It has never been my experience that horizontal head is as much of an issue as the calculators think.

See if you can find a PanWorld 150 used and try it out. This pump is about half of the wattage of the next pump up. The PanWorld 200 should be able to easily handle this, but it is a large wattage jump.

I would use the same size pipe as the output of the pump. Street elbows where you can, or spa flex.

You can usually find Iwaki, PanWorld, BlueLine used if you look for a bit. These are incredibly reliable pumps and nearly no need to buy new.

That should be plenty. It's important that you have a high ratio of flow because you are pushing water so far. You need it for temp regulation. I depend on my MP40s for flow as I am only at 3x return flow when I have my UV piped into the return loop. I get closer to 5x now that the UV is in a closed display loop. I hate the tubes in the display, but I'm trying to kill off dinos and it seems to be making a difference.

Invest in a kill-a-watt for accurate power consumption. Also, consider that your lights are only on half a day and your heater may not cycle that often as well. You can also use a meter with an amp clamp and multiply by your voltage to calculate watts. Everyone should have a good meter in their toolbox! You can add on an amp clamp to most decent $100 models.

For 100g total, you aren't going to be drawing much power. Maybe 5a@120v(12kWh/day) on average considering the large return and low amount of LED needed. You aren't growing weed here brother. We are talking pennies...

150g total

I run a basement sump, 40 gallons with a 120 display. I calculated 12' vertical and 16 horizontal. I used 4-90s and 6-45s. I ran it on a mag 18 with 1" pipe for 6 years, flowing around 400gph. I recently upgraded to a jabeo 24000. I run it at around 50% through 1.5" pipe. It flows a ton, have not calculated. Easy to tune overflows. It says it is using 105 watts, have not verified. I am certainly happy with it.

Thanks for the input.I found the Jebao 20000 on Amazon and might give it a shot. I would prefer to have a submersible pump instead of an external one so I don't have to drill my sump.

I got a Jaebo for my closed loop UV. I think it's a great buy, however the steps are really not that different than full blast. I get about 350 on 1 and about 400 full blast. This can be overcome with a gate valve, however if power consumption is crucial, this trait should be considered. With the jaebo, you can get from Amazon and not feel bad if you have to return it. Maybe go with the 20000 first and if that doesn't cut it, get the 24000.
