anyone tried to using Jebo WP40?

[HippieSmell]

It's probably been asked already in this massive thread, but does anyone sell these without the controller?

not currently. hopefully in the future....

OK guys let me first admit that I am too l any to read through 100+ pages of posts...

May I just ask, has anyone put one of these in a Cube tank?

I have a 93 Cube... Just wondering if the wp40 is a good option for a Cube or not. I'd like to make some waves, but wondering if the square footprint will hinder that ability..?

[Ron Reefman]

I'm guessing about 3' x 3'? The WP40 will be a lot of flow in a tank that size. And while you can dial it down, why not wait for the WP25 to come out and get 2. That way you the flow you want and can cover more area.

I have a WP40 in a rather full 180gDT and it's more flow from 1 pump than I want. I'll be getting 2 WP25's for this tank and a couple of others as soon as they come out.

Hope that helps?

Ron, if power goes out to the pump, and then power is returned (as if placed on my apex controller) does the pump start pumping again or do you need to turn it back on on the controller it comes with

I can answer this one. It picks back up where it left off.

I'm going to order one from fish street. Am I wrong but they were $85 plus shipping right. I looked today and they're $75 plus shipping. I thought when products get popular they are supposed to go up on price not down.... I'm on the fence about a MP 40 but why are so many used ones forsale? Are they not all they are $cracked$ up to be?

Sunce you can turn the pump i would put it in a corner facing the opposite corner. On wave mode my 4' almost spills water. On else its perfect flow it might work good it could also be too much. I bought a universal power supply to tune mine down if needed. I dont use it but it was obly 12$ so if youvdecide to get one i would get one of these also .

[BrooksReef]

Okay... so from what I have gathered, one on a 135g (60x20x24) is going to be enough? Or should I do 1 on each side dialed down pretty low?

I'd do 2 full blast on else if it were me, unless I was doing a softie tank

Can you direct me to the universal power supply that you purchased? I'm thinking I'm going to need to tune this thing down. TIA

Jebao told me this could damage the controller.

Unplug the controller
Remove the sensor
Then turn it back on.

Hope this works.

I thought if you leave out the sensor it will stay on high flow, and not the night mode. I never installed the sensor, and set controller to else mode.

[insanefishguy]

I know it's been said that the universal power supply is an easy fix but not good for the electronics. Some of you have been running them like that for a while now. Any issues so far?

Yes. That is correct. with out the sensor it will stay on normal or high mode.
That person was having a problem where when he removed the sensor it would stay in night mode and I thought they removed the sensor while it was plugged in and running.

That can damage the unit.

I've been using mine for about 2-3 weeks while I'm waiting for my PWM board to arrive.
No problems so far, but I think it shortens the life of the motor.
So rather then lasting 5 years it may only last 1. (These numbers are just made up. No one know how long they last yet).

This is just an assumption based on no real facts correct?

What's an assumption?
The statement that lowering the voltage will decrease the life of the pump. As far as I know this is an assumption based on experience from other pumps or devices that have been dimmed this way.

or the life span that I stated of 5 years down to 1 year. That is totally made up number based on nothing. Just a figure I pulled out of the air and SHOULD NOT be used as a basis for purchasing ot not purchasing the pump.

This. Especially since it looks like Jebao will be offering it as an option soon. I have seen a few saying this same thing about decreasing the life span of the pump but haven't seen any facts to back it up.

+1. Haven't seen one single documented fact or reference to any related or published article to support such claim.

I have one in a 120 cube (30x30x31") and its perfect. That said, I have it 2/3 of the way down. At that depth the wave effect is minimal in any mode. I have it aming up toward the othe side of the tank (so it disturbs the surface on the opposite side of the tank). The weight of the water being moved makes this pump the right choice. I run it in else mode, though I have run it in all the others for more than a day before I settled on this mode.

I plan to get a wp25 for the other side of the tank and mount it very low for some additional current.

It seems like 2 wp25s would work in your tank, but I wouldn't be afraid of a wp40. And as it has been said, order it withe variable power supply "just in case"

One more thought. This pump, like any other will collect debris, and slow the flow. I always prefer a bit more flow at first because it will get slower.

[salty joe]

I'd think any heat buildup would be indicitave of a shortened lifespan.
Maybe one of you guys with more than one pump can run one wide open and another at say, 12V, for several hours then pull the impellers out and see if one pump body is warmer than the other. Also check the controllers for warmth.

I noticed electronic components at the rear of the pump, evident through the epoxy. The perforated cirrcular disc has to be removed to inspect this place of potential heat buildup.

[Sacohen]

I haven't seen anything documented wither especially related to this pump, since it's been out such a short time, but if it's a chance you are willing to take great.
Some people don't want to take that chance.

As I said I'm currently using a LED dimmer and waiting for a PWM board.
SimonmSLK I know you are using at least one PWM board and have another one on order.

There is no proof either way that lowering the voltage will reduce the life, but someone stated at one time that it would based on their experience and others have taken to that.

Say a device requires 30 watts to work... at 24v it would have 1.25amps flowing through it to produce 30 watts... at 12v it would now have 2.5 amps for 30 watts of power... and by the time you reduce down to 6v you're now looking at 5 amps

bear in mind... as I said previously I still don't have one of these, and see lots of confusion... so we'll get into how the electrical load of the pump setup would work...

we're going to stick with 30w, it's a nice number and I like it. (actual wattage will vary with speed I'm sure, but I can't verify anything)

24v max speed is as said previously, 1.25amps to make it work

If you maintain 24v and run a 50% duty cycle, your peak amperage stays the same but average current would drop down to .75 amps

Now if you go with 12v for 50% speed and keep it at max constantly on that your amperage is now the 2.5 amps constantly. You can see the difference in current pretty easily right away... .75amp average vs. 2.5amp draw

Trying to drop to 30% speed with pwm vs. voltage is another big hike... .375 amp average on the 24v pwm circuit vs. 4.16 amps on the 7 volt circuit...

Wire, pcb traces, coils, they are all designed around given numbers... Your traces have to be far enough apart so that you can't short between at a given voltage.. and wire insulation must be sufficient for that (these numbers decrease at lower voltages, meaning less insulation and less space... so should never be a problem)

gauge of wire, and width of a pcb trace, as well as the gauge of wire used on the stator of the motor, all must increase in order to carry more current. Otherwise it gets too hot and burns up, or over time breaks down the insulation of the stator and shorts it.

This is the basics of how it works, and why some people have expressed genuine concern with lowering voltage, and it's a valid point. There is ALWAYS an acceptable range, and I don't know exactly what their control is doing or what... that's up to some of the guys that have one to figure it out. As far as I know at this point, that control could be regulating down to 5v anyways and just passing through the supply voltage, which would mean the control is safe but the pump may not be. There could be circuitry in the pump to protect from too much current as well too.

With the unknowns of the project, I personally would just nix their control and build my own 24v pwm circuit to run the pump. That way in my head there would be no question whatsoever as to what the pump was doing or if I was causing any damage to it

Best explenation in this thread that I have seen...
This is probably true, but also it is important to note that the pump could have a 10 yr life span and we are cutting it down to 5 years or so... I could live with that... That being said, I am running mine at 24v for now...

Maybe I'm being really dumb here, but this pump already operates on a wide range of voltages. If the lower voltages are the most damaging due to higher amperage, then wouldn't the worry be about night mode or L on a variable power supply? On a wave mode or else it wouldn't be low enough for an extended period to cause major heat build up...
