Looking for reliable submersible pump

  • We are currently upgrading MFK. thanks! -neo
Yeah it is really hard to keep track of the different Jebao DC pump models, but in fact with each there has been some improvement, if even small.

Actually though the DCQ is the latest model -- the DCW's came out about the same time as DCP's (only the power range is lower and unlike DCP & DCQ their Controller readout is in dots instead of digital):

DCW:
1380511

DCP:
1380512

DCW:
1380513

DCQ:
1380514

The DCQ line is also supposed to be quieter than previous models, which I can attest they are nearly silent, but oddly it doesn't have the sine wave technology that the DCW & DCP boast -- anyway they're both pretty darn quiet.

Yeah as for sound they are pretty silent. My air pumps make more noise.

I prefer the dots instead.of digital. Less temptation to tinker :)

The dcq got the sinewave function as well. Hold feedbutton for a couple of seconds and it will switch to sin wave.

Believe me Tobias bro I don't really understand all the techno-electric stuff, but in this case we're talking 2 different things. Yes both have Wave function (to alternate the flow, just like in a natural reef), but Sine Wave is not a function, I think it has to do with how the unit converts AC to DC.

This site: https://www.theaquariumsolution.com/product/8178/311 describes it better than I can -- it's talking about Jebao/Jecod's wave makers but the principle is the same:

"Conventional AC power is produced by rotating machines (alternators) that produce a smooth alternation, like that of a pendulum. It is described mathematically as a "sine wave". It is the ideal waveform for the transfer of AC power.

When converting AC to DC power most DC controllers will convert the AC power to a DC Square wave or DC modified square wave. For the most part a DC Modified square wave will often emulate a True Sine wave reasonably well but the driven pump will often operate with audible levels of noise and a slightly ‘choppy’ operation due to the stepped square waveform compared to a smooth True Sine Wave.

Utilising True Sine Wave Technology the new SOW Sine wave pumps result in a quiet and smooth operation that extends the lifespan of the wavemaker."

On the DCQ controllers though (and on the box they came in) I just double checked and it doesn't say Sine Wave as it does on the DCP controllers and boxes. Instead it mentions (on the DCQ box) that it has "Four-pole electronic motor, ultra silent", which I 'think' are supposedly quieter and have longer life than 2 pole motors. Beyond that is getting way beyond my electro-IQ.

Ill check my boxes tomorrow:)
 
Simplicity 3200 set up for about a month now and I'm really loving it I decided to go that route instead of the jaebo so that I would have a local company for the warranty in case it's needed

I love the mag drives. They are the best IMO but they suck up the juice more than any other pump

I know next to nothing about such pumps, what are the advantages of mag drives? It looks like they come in both external and submersible units: if external I wonder what the noise level is like?

Ive never heard anyone complain about mag drives. From what i heard they are top notch
