1.2 Litires a second / 1145 GPH

5 Meters Head / 5 BAR pressure (10 max)

3 speed settings

Inline

= 40£. or 60$ ..

er. yes.. its a central heating pump.

here we are speding 40£ on peices of crap .. that are about 100th of what this pump is

With the pump being metal, SS or cast iron, your system will corrode very quickly using that pump. The pumps we normally use are plastic where the water flows so corrosion is not an issue. The specs of the pump look OK, but how much is 5 bar?

Wouldn't the anti-corrosive fluids we all put in keep that from happening? This pump looks like a beast, but I wonder how much true temperature drop you'd see with it, and how noisy it is? Does the pump put a lot of watts into the water? If it's a central heating pump, they probably don't care if it does - that helps their cause. But not ours. That many watts would be like adding another overclocked processor to your line, along with the pump!

I'd love to see you try it and report results though!

iam trying it .. first of all .. the pump puts NO power into the water its insulated it. also puts no heat into the water... its also quiet... ever heard your central heating pump?

and its made out of cast iron, but its coated with somthing. not sure what but its will not corode.. (its designed for use in a copper loop.. using water + antifreeze .. (centralheating...)

anyways ill post a report on specs tomorrow. when i get it up and running ..

the one slight problem with it. is that it needs insulating against condensation on the motor coils. if you wanna use it for sub ambient which i do.

im opening the pump up now ill post some more pics

I have wondered about using pumps like that for a while but never had one handy to try out- I am really looking forward to hearing your results!!!!!

Thinking different is ALWAYS good, IMAO, even if the ideas don't always work out.

Keep us posted!:D

5 bar pressure on pvc tubing. hello .. BANG whoose water every where .. *shrugs* maybe.. ill have resullts in .. 4-5 hours. wish me luck!

5 bar is about 74 psi, I hope your PVC can handle that.

That looks like one of those Rainbow Lifeguard Quiet one pumps with a different impeller housing. If I recall, it also uses a GrundFos motor. The specs look similar too. The only difference besides the housing is the price :D. Looks like a promising pump.

Omg!! :D

Definately put that in the rig. With that head. you could put the radiator on your roof.

im just gonna add to this thread, but grundfos does sell these pumps in the USA, and infact, they make a 38GPM pump. 38GPM is equivilent to 2250 GPH. :eek:

me wants one of those :drool: but i shouldnt get one becuase if something breaks i dont want to be impaled (sp?) by water.

but that one that enyo has looks pretty good. and i might get one :D

Enyo
08-19-03, 08:46 PM
ahem.. people.. grundfos also do pumps with 3000GPM .. so.. 20kGPH +? and with around 500ft head. so ..

lol.. :D i still want one!

Ok dokey! update time!

THE PUMP IS RUNNING.. :)

it is silent.. utterly silent .. it is warm but only at the back of the pump not near the water.

there are NO vibrations at all

but..

ive only got 16L of water in my res and its only about 4" higher the water in takes and out takes on the tank.

so the water IS foaming as i belive the pump is so powerful its sucking air into the water with the water..

but apart from this TEMPORARY (i need to reiforce the rack before adding more antifreeze) this pump ROCKS utterly the flow rate .. is.. astounding... the little bubbles are flowing faster then i can track them..

if your in the uk and watercooling .. GET THIS PUMP

right now iam leaktesting everything on the much higher head rate of an hydor l30 + grundfos (6m head total) but so far no leaks at all

ill update with temps

I'm looking into one of these pumps for my external box,
how did you deal with the pressure?

Yeah, cool that you're testing this for us. I've been thinking about thoose pumps too. They're cheap, they run for years, has an excellent head. Only drawback is the power consumption and pumpheat.

If you would make a water loop from the exit (to a res) back the entry and run the pump, you'll notice the degree of pumpheat this thing will induce.

Run the pump with warm water (35C?), empty the water inside pump + res.
Add a precise amount of cold water, and you read the temps when you start, do another reading after 5-10 minutes of running.
With those figures you should be able to calculate the amount of pumpheat introduced into water.

You must prewarm the pump to take out the effect of the cold housing heating up.

whats its net positive suction?

if the head is to strong you can put the outlet into a radiator first to take the brunt of the force and use the suction to drive the system if its good enough.

oh how bout some physiical dementions in metric too if you can please

Enyo
08-28-03, 06:27 PM
ok..

problem is due to the setup ive got the pump does NOT like condensation.. so its very hard to fill the system .. ruling out any tests..

but.. the pump dumps very little heat into the water. less then my hydorl30 at least.

the way the pump is designed is very differnt to your normal pump .. this pump does not freewheel when theres to much pressure. there is a very low flow rate drop at higher pressures as ive found out.. if i run the thing at setting 3 the noice of the water hitting the bottom of the fish tank sounds like thunder.. but ill just cut the pipes shorter to fix that.

right now im insulating everything.. so theres loverly expanding insualtion foam everyhwere. including on the side of my moniter :-\

dimentions are 12cm x 10 cm x 10cm and 2.5kg weight.

no problems with the pressure as i use jubilee clips so aslong as they are clapmed down REALLY hard with good tubing .. no leaks at all .

ive got 1" plastic tubing clamped on the 15mm pipe outlets (copper pipeing sawn off to an edge) and with no leaks at all with a good tight clip.

suprising thing about the pump is that.. it is INCREADIBLY quiet. its way quieter then my hydor l30 .. the only way i can tell its on is from the noice of the water passing through the fish tank res.

illbe running tests tomorrow.. once ive cleared all this dammed gunk off everything..

oh and btw in the uk these pumps are VERY comman place. check your central heating pump its probably the same one.

you can find these pumps at plumbers, diy.. building suplyers (kemps, plumbline,, etc.. )

for americans though.. it will be very hard to get one.. beacuse you'd have to buy the pump (60£) and adapters and pipeing to reduce it to somthing like 15mm pipeing which you can clamp stuff to .. by then the total weight gets.. High.. were talking 5kg+ so.. shipping would be hard.

remeber we use BSP + imperal pipeing and you use.. NTP + (metric?) pipeing,

if your intrested. i could probably ship one out to you. or you could contact grundfos (www.grundfos.com) but the us part doesn't deal with central heating pumps. but it still has some SWEET pumps.

Hehe, two almost identical pumps is found in Sweden.

You can buy them from the Swedish version of Home Depot, (almost)every mans favourite Swedish store "Clas Ohlson".

They sell the exact same pump, but it is grey instead of Red, and it's called "Nocchi SR3" or "Myson CP-53-S". They both feature the selectable speed switch and all.

It's weird, coz, Grundfos sounds so scandinavian, so why isn't it sold here??

Nocchi sounds totally Italian to me. Myson... well.. have no idea where that's from.

Well, selling Grundfos in England, selling Nocchi in Sweden, I bet the Italians are mostly buying the Myson unit.. hmm.. made(branded) in England?? It's an Import/Export customs/tax evasion hoax I guess.... Weird stuff, but the pump seems intresting enough.

Quite cheap also, cost 500 - 700 SKr = £37-51 / $58-81 US.
Well.... Enyo, how about pumpheat into the water? Any news about it?

It simply has to spew pumpheat into the water... I mean, metal housing... 100+ W motor...
I think I read somewhere here on OC.com that only a fraction of the pump energy got converted into waterforce, like about 10%, the rest 90% is pumpheat.

Anyways, cheers Enyo and keep us informed! :)

LoL Nice job :thup:

If I ever went watercooling I would buy me one of these - no more crappy plastic devices for me :) - you could try rigging it up with hosepipe (reinforced) and then Really opening her up...

Enyo
08-29-03, 06:10 PM
pump heat is suprisingly low.. acutualy.. i left it running for a while on setting 3.. not much heat at all got to the water. on the back of the pump there is a shiney metal screw which acts as a heat sink disiapting most of the heat. (the big round screw you see in the pics)
that screw gets VERY hot. but the rest of the houseing just stays warm..

*shrugs*

as im gonna be using sub ambeint -20c and below liquid pump heat means nothing to me as the pump leads directly into the fridge res (30L+)

but if you are worried about pump heat .. as the body is metal .. turn your pump into a secondary radiator.. stick 120mm fan on it spinning slowly. maybe some stick on ram sinks too.. in the hot parts..

oh one IMPORTANT thing about this pump is unlike normal watercooling pumps if you put pressure on the opening (ie put your hand over the outlet) the pump will just freewheel. and do nothing.. but this pump uses a much differnt rotor as you can see in the pics .. so if you put your hand over the outlet. id dout you'd be able to put enough force down on your hand to stop the pump from pushing it out of the way.

so beacuse of this the pump ALWAYS has to be used in a loop. shutting valves with the pump on...

if the water fails to loop pressure builds up.. hoses blow off.. etc. not fun. the pump itself would be fine .. (rated to withstand 10bar pressure .. ) but your computer would't ..

*im siiiinging in the rain* etc. :D

Ummm...? quote: "if you put pressure on the opening (ie put your hand over the outlet) the pump will just freewheel. and do nothing.. but this pump uses a much differnt rotor as you can see in the pics .. so if you put your hand over the outlet. id dout you'd be able to put enough force down on your hand to stop the pump from pushing it out of the way."

Soo... if I plug the outlet it will freewheel and I can't stop the waterflow at the same time ??? :) We've got a typo here haven't we?

Anyway I understand that: restricting the INLET will kill flow, the outlet is powerful.
I went to Clas Ohlson today... I touched and held the Nocchi.. Mmmm... 1 1/2 inch threaded fittings... cold metal... several speed settings... Ohh!!.. yes!!! (overclocker-porno for sure)... but the dreaming was killed by the fact that the dude behing the counter couldn't produce the (same as above)Myson pump that was on sale(200 skr cheaper)! Crap.. I had to mail-order it from headquarters. Sad ending of a good day. I will not give in! I shalt make it mine! All good things come in three, My Hydor L30, My Hydor L3000 and My soon to be Myson. and... and.. duh! I already have a third pump..

I have a teeny weeny Sicce micra. It was on sale !!! I could't resist it!!
Yes, I know that Sicce micra shouldn't be mentioned at OC.com...
YES I know it's blasphemy.
Sorry !!!

Enyo, where exactly did you get the pump from?

I've done a little searching and I found the pump models listed in one of your pics...

http://www.holcombe7.fsnet.co.uk/pump3.jpg

Found it at onlineplumbingsupplies.co.uk;

http://www.onlineplumbingsupplies.co.uk/acatalog/Grundfos_Pumps.html

Problem, is, they're asking £94 and £101 respectively! (UPS15-50. UPS15-60)


So yeah, where did you get yours for £40 ?

08-31-03, 09:05 PM
I took the front off my Quiet one out of curiousity, and it's the exact same rotor. The more I look at the specs, the more I'm convinced the Grundfos and Quiet one are very close cousins. Max head, flowrate, and power consumption are very close. The big difference is the Quiet One isn't three speed; I wish it was. Unfortunately the Quiet One is twice as expensive and not being offered for sale anymore.

you can pick up this pump at any hardware shop in the UK.. ive seen them in virtualy ALL DIY stores .. some times even cheaper then 40£

That is incredible! Seems it would be great with external cooling boxes that cool more than one computer!

If I ever build an external box I will look into getting a large res and that pump!

But really, it does seem like a nice pump. I am assuming that it's working very nicely as you came back a while later to let us know they are still for sale.

Do you have any data that says how it performs compared to other pumps? Like mentioned before this could be great for an external cooling unit, heck I'd put it in my basement and run some tubes from there... just for the fun of it. :p

heh, it worked fantasticly for ages till my wb failed due to corrosion (cu block with alu top >_<)

you have to be very careful with it though, i did try using it in a water chiller but it shattered the tank i was using to hold the liquid..

don't have anything to really compare it to at atm, since my hydor died when its prop chamber got filled with metal fillings from corrosion and now jams.

atm the pump isn't running as i need a new WB and also to get my rig sorted out, ill be using it on

4000+ san deigo
A8N sli delux (being naughty and freezeing at bios splash after passing post)
1gb of corsair value ram (166mhz .. probably gonna be changed)
80gb WD
hiper power 580w type r
7800 gtx

im using it with a rather large heatercore taken from some large vehicle, the fins of the radiator are very densely packed

ill post back when i get it all up and running
