I was just about to order a reeflo super dart gold to use as a return pump but now I'm considering getting an L1 instead... it sounds very interesting... I hope more information comes out soon

Do you guys think these pumps could be used externally. And a guess on fitting sizes?

Will have to see one in person to be sure but I am pretty sure that blue fitting on the inlet and outlet is just a slip x fpt adapter.

You would still need a union on the inlet and outlet in order to separate the pump from the plumbing for maintenance.

From the pictures it looks like the output fitting is a little smaller than the input. I would guess for the L1 it would be 2" in and 1 1/2" out like other similar sized pumps

You are right that looks to be the same pump and allot of manufacturers are now starting to use this same pump from what I have seen coming up.. Also look at the controller that is the same as the new RODC pumps use, could be a modified version of this pump. I think RlSS is coming with a pump based on this model..
I am guessing that Ecotech will charge more than most. I think we will see allot of manufacturers using this pump... Basically there will be slight variations of this pump everywhere. This also does not mean it will be anymore reliable and only time can tell on that.

They can absolutely be used internally and externally. If I had to guess, the M1 will have 1.5" input and 1" output. The L1 will have 2" input and 1.5" output.

As I said in my previous post. The issues with the cheap DC pumps is the power supplies and controllers. You can bet that Ecotech will not be using cheap power supplies like all the other cheap DC's and we already know that they are using their own controller. As such, I think these pumps will prove much more reliable than the other ones that look the same.

I will add a bit more info based on my research. Like with the rest of the DC pumps, these will most certainly have the soft start. This is pretty much a guarantee since soft start standard with all of these BLDC blocks. What that means is that these pumps will not be able to ramp up and down really fast like we can do with our controllable power heads. It will take several seconds to ramp from 0 to full power as well as from a low flow rate to full flow rate. I bring this up because a fast ramp rate is really intriguing for those that would like that ability in a close loop scenario.

Nice!

So it looks like the blue "union" things are meant for hard plumbing and not soft since they use an adapter to attach the hose.

I dont know the vortech power supplies are not that great.. They are just standard power supplies. I just replaced one for my mp40 and bought it from somewhere else for 1/2 what they sell it for...
It dont matter if it is the most expensive product on the market or by the best company in the world Longevity is only found out in time.. Flaw or errors in manufacturing happen to the best especially when you rely on Chineese manufacturing.

looks like the block is the same is the BLDC8 but i wonder why the wattage is 80w vs the 67w the BLDC uses. also wonder if it has the same "no water shutoff" feature? also looks like it will be able to hook up to thier battery backup which is quite nice. Depending on your setup, in a power failure, your return pump might actually oxygenate the water more then a power head.

Vectra has a slightly high head pressure and that probably where the extra few watts are coming from.

That or they are using a higher wattage power supply. The Block is a 24 volt block but a 36 watt power supply could be used since the control varies the voltage. That could result in slightly higher power consumption in the name of a more reliable power source that is always under utilized.

Yes! indeed. 36v will make it more reliable. Higher voltage, lower amps.

So what does this mean to me? Higher or lower energy bill?

Marketing on the pump indicates a closed loop mode, so the answer is definitively yes. If I get one, that is how I will use it.

Likely still lower than most pumps but that is all relative to what we are comparing to. Using a high voltage power supply if in fact that is what they are doing doesn't necessarily mean more power consumption since it's all about current draw and not the DC voltage. It could be slightly higher than a comparable DC pump or even lower but we really don't know that. I will also note that often the power consumption is under rated on many Chinese pumps so side by side with a comparable DC pump, it could be identical and Ecotech is just giving an honest rating under worst case conditions.

Heat is measured in watts, not amps. A 100v 1A line will give the same amount of heat as a 1000v 0.1A line because the wattage is identical.

That's not what I got out of those two statements. Input voltage won't equate to more or less loss unless the motor is made for a very different voltage.

You are correct, however my comment was discussing the delivery of power. The gauge of wire is the limiting factor. The more amps, the larger the gauge of wire is necessary to allow those amps to pass through. This is the problem with low voltage products.

Wire gauge comes right back to wattage, not amperage alone. I can push 5A through a 24AWG wire without any long-term issues if the voltage is low and in turn keeping the wattage low, preventing the wire from heating too much.

Most of the DC pumps I've seen are using 20AWG going to the motor. I've got laptops that consume twice as much power using the same (or thinner) gauge coming from their DC supplies. All about heat management.

Do you know the Joule effect o law....?????

for me the problem with these DC pumps has always been dissipation (desing). Usually greater dissipation means more cost and size ..... only compare the size (and cost) of the Royal Exclusiv controls with the other brands.
