noise of the MD55 pump

[bwilly]

is your MD55 noisy..?

I just got one. it seem veri noisy..

giving a humming sound. quite loud when the cabinet is open.

a humming sound can still be heard.

[AlfaRomeo]

For mine, it was noisy when it first ran for about 1-2weeks. After that, it quieten down a lot but i dunt think it will ever be as quiet as an Eheim..

[Achilles Tang]

Iwaki or Resun?

[AlfaRomeo]

Resun I believe...

[bwilly]

ah sun yes.. oh.. the sun so bright.. the sea so wide..

n your eh hmm.. is so..

ehiem..

doubt u can hear anything.

but the power output from 1262 is not good..

I can't tee off to my skimmer leh.

[Achilles Tang]

There is a quite a bit of difference between the Japanese Iwaki and the China Resun.

The fan size in an Iwaki is bigger and cools the pump better.

Resuns tend to run a lot hotter.

Won't be surprised if the motor is also very different.

Bwilly, you can try cushioning the Resun MD pump or cover it slightly with insulation material to block the sound if it disturbs you.

[AlfaRomeo]

AT, would the Iwaki be quieter than the resun?

[Achilles Tang]

From my observations, yes.

[AlfaRomeo]

Bwilly, if you got the $$, u might wanna have a look at ATK pumps which are pressure arted for 6000L/Hr and using only 80W. Dunno how quiet it is tho.

Or you wanna have a look at Hon's Red Dragon pump too. quiet

[bwilly]

of course iwaki is almost 100% more X..

the pump is veri hot, I won't recommend it covering..

at least the noise will dun anything, but hope later have drastic effect..

other than it being hot n noisy, I am happy with the pump n purchase.

but with the pump I am looking at a chiller now.. damn it.

slowly lah..

this pump already cost me quite a fair bit.

plus 2 tunze.. where to produce $$$..

I may upgrade, but no so soon. still quite happy,

but like to find out feedback from fellow user.

I got this rubber 3M stick on, it may reduce the

vibration abit.

see 2weeks later how. who knows I get used to the sound,

tik it run so silent.

Alfa,

The ATK pump model closest to the Iwaki MX-70 in litre/hr capacity, cost around S$890 to S$1,084 excluding freight, but has a weaker pressure rating of only 3.6m head vs the MX-70's 8m head.

Pressure-rated pumps are classed differently from one another.

IMO, the Iwakis are still the best in terms of price point/performance although running costs should be considered carefully.

Comparatively, the Resun is cheap and even if it should spoil, it won't hurt to buy another one to replace compared to an Iwaki!

PS - I am also joining the Resun MD gang now soon! Going to use the MD55 to run the main returns and use my MX-70 to run my twin beckett Reef Maniac DK-1 skimmer.

welcome to the club..AT!

with the kind of price, u can buy many many on standby..!!

[Hon]

The fan noise is horrible, thats why i shelved the pump liao

[bwilly]

shelve..?? care to elaborate..??

[AlfaRomeo]

Hon, you shelved Iwaki/Resun or the Red Dragon?

[Hon]

I shelved the iwaki and use the dragon. But later sold the shelved pump to someone else that enjoy the humming tune.

Can try to seat the iwaki/resun on a 1inch thick foam with a piece of egg-crate in between to give a uniform spread of the pump weight. For the humming sound, can follow what AT did before, built a egg-crate box and covered with masking tape to muffle the fan sound...

[AlfaRomeo]

What are the specs for the Dragon again dude?

[Hon]

Using 2 dragons now. A 12m3 for return while the 8m3 to drive Aerofoamer 830..

Spec not beri sure. Can run beckett to my satisfaction lah ...

[planetg]

dunno if this helps but my iwaki is almost pitchless!

and make sure the noise is fan noise and not cavitation.

cheers

[Anthony]

my resun MD 55 its very quiet...

but MD 40 its so horrible.. !!!. the humming sound its so unbearable... worst!. i come withEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE sound too .

anyone have md40 problem?

[DeepBlue]

Heard it last evening....Anthony is not exagerating....his MD 40 gives out terrible sharp and irritating noise(LOUD)........ He bought it from our sponsor recently(2weeks old)....think something is wrong..(Something should be done soon to ensure customer confidence )

[yazid]

Just wondering. do we need to oil the MD40 to remove that screeching sound?

[Anthony]

Just wondering. do we need to oil the MD40 to remove that screeching sound?

i dont think so loh ... i guess i got a faulty pump... SHOULD i get a 1 to 1 exchange ?.

a md 55(higher flowrate) + a fan works so quiet!...

[Achilles Tang]

Having used two Aquaconnect Red Dragon pumps before for a project... I can say they are very good for flow applications with minimal head.

For pressure-rated applications with high head pressure... best to get the proper pressure-rated pumps like the MD or MX pumps.

I have seen some tanks with so many 90 degree elbows that what comes out of a pump is like 'pang jeo' like that! At max only 30% output vs the supposed capacity of the pump.

We should all try to minimise head pressure as much as we can.

For tall beckett skimmers.... no way the Red Dragon pump will outperfom an Iwaki.

[Achilles Tang]

Just wondering. do we need to oil the MD40 to remove that screeching sound?

There shouldn't be any screeching sound from the pump.

Is it coming from the fan or the motor? or the enclosed impeller area?

Unless you can identify it is really the motor and know how to open it up, disassemble and oil the parts that is making the noise and put it all together again!
