Iwaki MX100 vs RD 10m3

When the blue beast meets the red dragon......

[roidan]

Let's recap the exterior of the blue beast...

very very solid and heavy outing metal casing....weighs probably just under 10kg....

casing is surprisingly quite resistant to rust even after few months of use compared to a resun md55 i used in the past which showed signs of rust.

[roidan]

exterior of red dragon......black plastic housing which definitely doesn't look as indestructible as the blue beast but can be used for submersible purposes...no rusting problems here..

weighs 4.6kg....about 1/2 of the blue beast..

When the blue beast meets the red dragon......

nice pic bro, more review please...

[roidan]

hehehe...thanks hamann

the internals of MX100..

to compare the 2 personally....the impeller housing of the blue beast seems more refined and well fabricated compared to the red dragon.....

[roidan]

The guts of the red dragon

can even see from photographs that the blue beast material seems more refined in comparison hor....

[roidan]

the punching arm of the beast....very nice impeller....again..the pic shows the quality of the fabrication....

[piglet]

more more more review & pic

Bro Roidan,

More please.........

How about comparing the actual water output strength, may be at 8 feet ?

[roidan]

Bro sugi...patient patient...will come to that..hehe

piglet..will do so...

The flame throwing spinning impeller of the red dragon....

again the material seems *cheaper* by visual inspection...but well made nonetheless

[roidan]

front cover of the blue beast......

[roidan]

The back of the front cover of the red dragon....

must mention something here....the front cover of the blue beast is secured by bolts that eventually will thread into the metal casing whereas the front cover of the red dragon is secured by bolts that thread into a plastic stand between the front cover/impeller and the motor body.....

i reckon that the threads in the plastic stand will not be able to withstand the removing/putting back of bolts during maintenance and so on as compared to the threads in the metal casing of the blue beast.

[roidan]

flow rate of the blue beast......

sugi...as requested by you...straight up 8ft is around 2.4384m ....so agar agar..

the blue beast should render pass 6000l/hr easily...

[roidan]

the red dragon will render lesser than 6000l/hr at the same 8ft at 2.4384m.

And this worsens as the flow undergoes piping work with elbows....tees....and so on....thus for red dragon users....it is best to employ a flow pattern with as little piping restrictions as possible...ie...try to return with as little elbows and other fittings as much as possible to fully harness the red dragon otherwise the fire breathing prowess of the red dragon drops alot.

anyway...please do not read off the shape of the 2 graphs at face value..because....both sets of axis are different

[roidan]

Blue beast is very hungry at zero head loss at full muscle stretch....

consumes up to 240W at our local power supply context of 50Hz....

but if u ask the beast to do alot of work....pushing high high or pushing against great resistance......he no mood to eat the full amount of food as he would usually and will consume less than the max of 240W....

[roidan]

The dragon in comparison eats about half as much.....and yet gives u more flow at zero to minimal head with its mystical powers .....but when u start to whip the dragon to force it to work harder at greater heights and greater resistance.....it may either breathe fire back at you and not work as well...or just drop dead from being overworked

so use the correct pumps for the correct purpose....

pressure rated pumps for pressure/demanding applications....

end of review for now

[roidan]

oh yah..mods can place this in product reviews if it is more suitable there?

[patrick123]

Roidan,

Iwaki is great, but the fan noise is quite noticeable. If you use more than one iwaki, it will start to be irritating.

Any good suggestion on how to cut down on the noise?

[weileong]

Bro, you're comparing one product that is mass produced, moulded parts which are much cheaper. The other one is individually CNC machine out.

However the iwaki are hard to beat for the price especially if you get from cheap source in Hong Kong.

[roidan]

use a cabinet to house the iwakis lor....sure muffle the sound.....if u want, remove the fan yourself and then use quieter fans to blow the iwaki.

yeah..the red dragon is very quiet when it comes to this aspect.

[alanseah]

not to mention cool when it run too...

well I dont think it's correct to compare a non pressure rated pump with a pressure rated pump...

It will be more reasonable if u compare red dragon to ATman or OR or any other non pressure rated pump....

[roidan]

cool or not....really depends and so far no quantitative figures yet....i was thinking of putting the RD in a toyogo tub and run it for 1 hr internally and externally and see how much the water temp rises...and then compare with the external mx100 running for 1 hr in the same tub

just thought of comparing the 2 since both are highly respected in their own right

yeah..for pressure uses, use iwaki.....

for non-pressure uses, use RD

Wow...now you are comparing a pump that is 1/10 the price of RD, but use 200% of electricity. How to compare?

This will be an interesting test. We are all dying to know the outcome.

It's like comparing a turbo car and NA car.

Both properly tuned, the turbo car will be less fuel efficient and the NA car more fuel efficient.
