pumps

Hey guys .. Got a question about water pumps

I have a 120GPH Rio 180 pump.. and an aqua via 1300 (360GPH) pump..

I plan to have the 120GPH pump pump water into the inlet of my via aqua.. then out of the via aqua into my system..

The rio will be sucking in really cold water.. so it's going to be like.. only 90GPH..

I know that if all works right the stronger pump will start a suction on the smaller pump.. increasing the water flow.. Is this going to be harmful to my little rio 120??

Do you really care?

Well.. Yea.. I mean the pump cost me 10 dollars lol.. I don't want it to fail though.. that would suck

How do you come to the conclusion that sucking "really cold water" will cause the rio to drop to 90gph?

anyway, if the combined restrictions in your system cause the flow of the aqua via to drop below 180gph then having the rio in series will help a bit, if it doesn't you'll actually be restricting the flow of the larger pump with the smaller one.

it won't hurt the rio, these kind of pumps don't have the pressure/vacume capacity to damage anything...

I've tested this in practice, been there, done that , bought the postcard

Well you see.. In my phase change system I only have enough room to fit the rio pump in between the evaporator coil.. in the resevior i have.. even that is a snug fit.. so I planned to either pump the water out using the rio to my larger pump.. or to just use the 3/8" opening on the bottom side of the resevior to go to my water pump.. then out to my system.. and then return back into the top of the evaporator resevior.. either way i need to have some type of other container for my aqua via pump.. there is a small leak in it so i can't run it "inline" .. it needs to be submerged.. I was hoping that this way would work.. cuz before the water gets sucked into the pump it gets brought right across the evaporator.. i mean the rio is like snugged up against the evaporator coils.. it's a perfect fit.. it's beautiful.. i figure since the water and stuff is going to be so cold the rio won't be putting out no 120gph.. more like 75-90GPH.. but once it got going the suction from my via aqua pump would bring up the GPH on the rio.. kinda equalizing things..

|PuNiSh3R| · 08-12-2002, 10:29 PM

I mean.. I'd like to have 200GPH going through my water block.. I know flow doesn't really matter that much when you start phase change cooling..

I know with an evaporative cooler.. using a humidifier.. flows of 90GPH from like 60GPH or something like that made no difference in the temps.. so GPH isn't a major concern for me I guess..

I just know that the rio couldn't push all of this system water around.. it's to cold.. and will be to thick.. with the anti freeze and all.. it just wouldn't work to well.. Plus I want to be using my via aqua.. I would of.. but it won't fit in my evaporator/resevior container..

|PuNiSh3R| · 08-12-2002, 10:32 PM

Plus.. I have copper tubing inside of an aluminum resevior.. The resevior is all painted.. except for one spot that's chipped out.. This will cause a major battery effect.. right? I just gotta use the good ol' water wetter right? I mean I'll have anti-freeze in too.. so I'd think that to be enough.. Or should I just clear coat all bare aluminum spots? Or some spray paint? I'd rather clear coat cuz I don't want to get spray paint on the copper coil..

You'd be better coating it. (clear is ok)

The small exposed aluminium is bad, very bad: the res will corrode, except that since most of it is coated, the exposed spot will corrode "on behalf" of the whole res.

Shallack time...

|PuNiSh3R| · 08-13-2002, 10:13 AM

I'll blast it with clear coating today..

I figure with the water wetter in and anti-freeze it wouldn't corrode anyway.

It wouldn't corrode as fast, but it will still corrode (you knew that, right?

)

|PuNiSh3R| · 08-13-2002, 12:43 PM

that is what i ment to say.. heh

I sprayed some clear coat on it earlier.. and I will spray my evaporator coil as well.. that should help right? that way the coil won't be like direclty exposed to water.. so it'll keep it looking nice and new for a longer time..

bigben2k · 08-13-2002, 12:49 PM

Hopefully the coating on the evaporator won't affect performance...

|PuNiSh3R| · 08-13-2002, 01:00 PM

nah.. it's to thin to do much of anything.. the coldness will still come out no problem..

|PuNiSh3R| · 08-13-2002, 04:03 PM

Wow.. I just tested it out today..

My results are great.

I hooked up the outlet of the 120GPH pump to the inlet of the 360GPH pump through 1/2" tubing.. 1ft long.

My test was a great success.

I turned on the 360GPH pump and it had enough suction to pull water through the smaller pumps inlet.. and the 360GPH pump had enough power to put out the same head as normal!

I then had the 120GPH pump push water through the 360GPH pump with the 360GPH pump off..

BAM! Worked great! Water spewed out of the outlet of the 360GPH pump and the 120GPH pump was able to keep the same head pressure.

I then turned on both pumps.. I stood up on a bench .. with a long piece of tubing (atleast 10ft)

I turned on the 360GPH pump.. Good.. I got my 6ft of head pressure like normal.. it was still set up.. sucking water through the smaller 120GPH pump.. then I turned on the 120GPH pump and the 360GPH pump .. damn! The head WENT WAY UP! I had to turn the pumps off because the water rushed up the tubing way fast! The head on the 120GPH pump is like 3ft or less.. Combinded with the 360GPH pump it was incredible.. a head pressure higher then 10ft!

All I know is that the water rushed to the top of the 1/2" tubing... and would of kept going if I had more tubing.. I am guessing a head of atleast 13Ft!

This proves pump redundency as well.. if one pump should fail.. the other will still have enough power to circulate water through my system. This also proves that I only need 1 pump on at a time.. say if silence is needed.. or I go to bed.. PC is left on and idling.. or.. if I turn off my PC.. I am going to keep the compressor on.. using the thermostat and turning the compressor down to like 1 or 2 power setting.. this way I can just turn my PC on then with out having to wait for the compressor to start chilling the water.

So I will leave the 120GPH pump on circulating the water so it doesn't ice up or anything anywhere.. Even though I am going to have anti-freeze in the system.. still good to keep the water flowing because it's less traumatic on the pumps to start flowing this freezing water around.

When I just had the 360GPH pump with no tubing on it.. just squirting water straight out of it's outlet.. and then turned on the 120GPH pump.. there wasn't much gain in the water height..

The only problem is that when I have both pumps on.. I hear a ticking sound in the 120GPH pump.. not sure what this is.. I hope it's nothing damaging to the pump.

bigben2k · 08-13-2002, 04:06 PM

Excellent! There's nothing quite like 2 pumps in series, the way that they should be!

|PuNiSh3R| · 08-13-2002, 04:55 PM

Just did some tests

Here are my numbers

Straight pump:
Rio 180 took 40seconds to fill 1 gallon of water

Aqua Via 1300 took 22seconds to fill 1 gallon of water

Rio 180 Pushing water through the Via Aqua w/ Via Aqua off:

Rio 180 took 45s to fill 1 gallon of water

Via Aqua sucking water through Rio 180 w/ Rio 180 off:

Via Aqua took 28s to fill 1 gallon of water

Pumps in Tandem:

Rio 180 pushing water into the inlet of the aqua via both pumps on..

Took 22seconds to fill 1 gallon of water.

There is no advantage in GPH with both pumps together.. The only advantage I have seen is with head pressure and of course redundancy. I don't hear the ticking from the rio 180 anymore now that I put more water in the tank.. so who knows.

Both pumps combined head pressure would be 8ft to 9ft.

It seems that both of the pumps working together doubles that.. I am going to get a straight piece of 1/2" 20ft vinyl tubing and test it out.. from a bedroom window.

Okay, now put you waterblock on the end and see what the timings are.

Yea know.. that's a good idea.
