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.

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! :D 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.

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... <_<

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.

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! ;)

      WHERE CAN I RECOVER BITCOIN-ETHEREUM-USDT HIRE TECHNOCRATE RECOVERY

      Fraudulent activities have been on the rise recently, particularly in the realm of Bitcoin and other cryptocurrencies. Many individuals find themselves ensnared in these deceitful schemes, and while I can chuckle a bit at my own experience now, the reality is that thousands of others aren't as fortunate. I too became a victim of a sophisticated scam, which taught me a harsh lesson in the world of digital investments. Several months ago, I came across a cryptocurrency exchange platform that boasted rates and returns far too attractive to ignore. The platform was dressed up with professional-looking graphics, glowing reviews, and promises of unprecedented returns. It seemed like a golden opportunity for someone looking to invest in Bitcoin and make a substantial profit. However, as many people in the crypto community might tell you, if something seems too good to be true, it probably is. Eager to take advantage of what seemed like a once-in-a-lifetime opportunity, I invested a significant sum of money—specifically, 805,000 dollars. I was initially excited as I watched my investment grow on the platform, and everything appeared to be going according to plan. However, the excitement soon turned to apprehension when I tried to transfer some of my funds and encountered endless delays and technical issues. My concerns were brushed off by the platform's support team, who reassured me that these were just temporary hiccups. It wasn't long before I realized the gravity of the situation. The platform abruptly went offline, and all attempts to contact the support team proved futile. My initial shock gave way to a sinking realization that I had been duped. The investment that I had poured my hard-earned money into was nothing more than an elaborate scam. I was devastated and felt helpless, knowing that I had lost a substantial amount of money with no apparent recourse. Fortunately, my story didn't end in despair. After some research and desperate attempts to recover my funds, I came across TECHNOCRATE RECOVERY a firm specializing in helping individuals recover their assets from fraudulent schemes. I decided to enlist their help, and they took on my case with professionalism and determination. TECHNOCRATE RECOVERY worked diligently to trace the funds and engage with various authorities and financial institutions to recover my lost investment. Their expertise and commitment were evident throughout the process. After a period of intense effort, they successfully managed to recover the entire amount of 805,000 dollars. Looking back, I feel a mixture of relief and amusement. I am fortunate to have recovered my money, but it serves as a stark reminder of the risks associated with cryptocurrency investments. While my situation had a positive outcome, many others aren't so lucky. This experience underscores the importance of vigilance and thorough research before investing in any financial platform, especially in the volatile world of cryptocurrencies.
