12v 500gph and 10$ all within a few minutes driving distance.

[ls7corvete]

Ok I was at wallmart the other day and knowticed that they had a bildge pump there that could work perfectly for our computers, 12v 500gph 330gph@3ft 9.96$ something like 1.4amps.

I am not saying that this is gonna be the MCP killer but it could make a very nice replacement for something like the via. I know ppl are gonna chime in with the reliability and constant usage but from what i see about the via things probably would not change much.

So does anyknow know anything more about this pump, maybe one of you out there has tried it?

If it comes down to it I will grab one and test it for the good of the forums ;)

[Como]

thats allot of amperage, it owuld take away from your system...i wouldnt run it on my PSU.

Its also probably quite loud...if i make the WC jump it will be for how quiet it is.

[ls7corvete]

Loud can be taken care of by running submersible, if you go for quiet and want a cheap pump make it submersible.

1.4a@12v=16.8w the MCP is 9watts so its a lil higher not enough to cause problems, I sure would not run it off a mobo header LOL

[felinusz]

Running submersible = heat, which is bad. As you said up top, reliability and constant use might have some play, although for $10 I'd say it's worth trying out.

There's also a saying, "you get what you pay for" that plays very true most of the time. For $10 I wouldn't personally expect much of a pump, and certainly not one reliable enough to trust my computer to without doing testing through extended use to prove that it's reliable.

[ls7corvete]

indeed, only way to tell is to test it. 16.8w doesnt bother me, its a trade off, heat for noise, and I usually choose less noise.

I will test this unless someone posts to make me choose otherwise

[themodguy]

I was under the impression that bildge pumps had a lifespan of about 2000 hours which is a year @ 8 hours a day or 120 days @ 24/7.

[WhatTheSchmidt]

how'd u hear about that?

[nocturnx]

Sounds like it could be a good solution for those that want to run a cheaper setup. What size are the barbs on it?

[ls7corvete]

big, def gonna need a reduction, I might be able to strech my silicone on it but I dunno.

The intake is just a hole, supposed to be run submerged, a lil modding never scared me though.

Bilge pumps are made for $50,000+ boats though. If you trust it for your boat you should trust it for your computer. Though most bilge pumps arent on 24/7...or at least they shouldnt be.

[AngryAlpaca]

Boats don't always need bilging. It's rare that they need it, I think. In PCs, 100+ watts are produced ALL THE TIME. 120 days... Four months... Probably poor quality... The Mag 3 costs 40 dollars, and lasts more than 3 years (warrantied for 3.) Which is the better investment?

[ls7corvete]

The pump was warrantied for 3 years. No its not intended for continous. Even if this did work out I would not compare it to the mag3, like i said it is comparable to the via if anything.

[Diggrr]

Well, try if you must, but everyone I've seen who's tried one is back in a month or so asking which pump to buy....:eh?:
Don't forget the hose clamps, becuase the pump's surging will hammer a hose off a barb in short order.

Luck!

[ls7corvete]

Hhhmm who has used bildge pumps before? I havent seen the thread, darn things were looking ok for this pump. Whats this with surging? the pump I saw used an impeller, different shaped than ones i have seen before but still an impeller.

BTW I have a MCP a quiet one and a via, this would be just for curiositys sake.

[JFettig]

back in my early days people were always trying billage pumps and having them failing. CPUFX sold a reservoir with a billage and there were always problems with it along with all their products;)

I have a 500gph black max bilge pump. Rated for 1500 hrs non continous use. Any way to check the specs on that one?

[Diggrr]

Many bilge pumps are self priming, and when an impeller blade passes the water outlet, there's a brief surge-relief of pressure. It's because the impeller is built so tight to the housing to make it self priming.
If you hold the tubing, you'd swear it's just the pump's vibration passing along it, but spray the water away from you, and you can see the stream of water surging.

[Shadowcat]

That sounds interesting but a bilge pump for $10 is not going to be continuous use. If you try it though, I would be interested to see pictures and what results you come up with.

[cpufan]

Is there a head vs. dischage curve somewhere. I see you are comparing it to a Via pump. Did I miss a link or reference to the specs?

[ls7corvete]

CPUFAN: Yes i was comparing it to a Via, not because of specs more because of the noise/reliability and most importantly cost that are possibly comparable between them, hopefully.

500@0ft
330@3ft

I have been thinking why is this not continous use? What can we do to give it a longer lifespan? Oiling, cooling brushes? Do you think it has brushes?

[diehrd]

Put it in and do a write up about it ..

[ls7corvete]

LOL ok ok expect something about it tonight. My water cooling is not setup ATM due to having to RMA my board with mounting holes.

Any ideas for a ghetto die simulator?

Maybe ill just have to build ghetto mounting bracket.

[wymjym]

as was stated earlier, several years ago everyone was looking for the sweet spot as to pump flow vs $$$$. Bilge pumps were tried everywhere I looked and most of them died within a few months.
fwiw I have been using a maxijet 1200 submerged for about two years now (knock on wood) no problems at all.
wj

[ls7corvete]

HHmmm well I guess im gonna have to look into mods for increasing lifespan.... at 10$ it still may be a temperary solution for the newbs who come along looking for something cheap.

[ls7corvete]

Its lets revive old threads day.....

Hehe, Anyways I just knowticed that I never even mentioned what I thought of the pump in this thread.

OK the pump:

Quiet, Running underwater should give a very quiet pump. I did not knowtice any pulsing, not saying its not there..... Just that I didnt knowtice any.

My favorite thing about this pump, It seemed to undervolt on my rheobus very well. I am not sure how this would affect the life of the pump, I am betting that the motor is not the "weak point" in the pump.

My plans:

Grab two of these, a couple electrical boxes to use as reservoirs and find a way to run these in series and submersible.

2x gives me the power I have always wanted and also the peace of mind nessacary when using cheap pumps such as these.

Anyways what do you guys think?

I keep posting theoretical components like these, Heck I pretty much have a whole water cooling system setup with theoretical components. Hopefully I will stop being lazy and get some of this stuff together for testing.

With any luck I will get all of it together.....

[9mmCensor]

Hhhmm who has used bildge pumps before?

Ok here's the sailors input.

The type of pumps we are discussing would be used in small pleasure craft so I will focus on that type of application.

Boats are shaped like a U or a V so at the bottom, water will collect because water always gets into a boat somehow (bad seals, waves, etc.).

Most often the bilge pump is located in the stern (back of the boat) in a recessed cavity. This is so that it will be where the water will move to, as the engine weights the stern down, and when the boat gets up on a plane the water flows to the back.

Bilge pumps have 3 settings. Off. On. And Auto. Off means the pump is is not pumping and does not engage. On means the pump is pumping regardless. Leave it at ON with no water entering the boat, and the pump will expell all the water from its cavity not be cooled (submersed) and overheat and die. Auto means that it pumps when there is water, but will disengage before the cavity is pumped out. Auto is the normal setting.

Bilge pumps are fine to run for hours on end, as long as they are submerged.
Typically they dont get usage for hours on end, usually its only a few minutes at a time, but they can handle it.

Of you threat them well, they should be fine for you, but I question their longevity, as its something I have never tested.

[ls7corvete]

Alright, dont run if they are not submerged, got it ;)

I was going to run them submerged so they are quieter and so I dont have to mod them, Now I have one more reason.

BTW what do you sail?

[9mmCensor]

BTW what do you sail?
I sail and teach dhingy sailing. Pirates, Petrols, Lasers, 420s, Albequors.
:cool:

[ls7corvete]

Nice, I windsurf mostly now but I have sailed most types of boats.
