anyone tried to using Jebo WP40?

From what I've read the light sensor automatically powers down the pump, reducing its overall speed.

Maybe the sensor just pump the pump in the low setting.

By the way this are just guests I know nothing about this pump, just trying to help a little bit to make this even better, I'll contact Roberto from Reef Angel to see if he can figure something out about this pump, it will be really nice if somebody make it work with a controller.

I already sent a PM to Robeto last week. He didn't have to much to say other than he thought it could not be controlled.

Actually Ron there is one test that would be helpful. If you could unplug the pump from the controller (with the power off) and then check the resistance between all 3 of the terminals on the pump end. If they are all the same (or close the same) resistance to one another, then it is probably a 3 phase brushless DC motor (BLDC). Not that any in tank motor is going to have brushes

I am pretty certain the motor is going to have 3 coils, so doing an DIY controller is going to be a lot more involved. Not impossible, just not as simple as PWM or 0-10V.

Hoping I am wrong.

It looks like it goes from Power source to DC power convertor with a 24V output to the controller to the pump, would replacing the power supply with a variable 24v voltage regulator before the controller give the speed control ?

Ron, I agree with you, I have had the pump running for just a couple days and so far I am very pleased. Time will tell how it really does. I don't mind the small whir of the pump ramping up and down. It is definately better than the the clacking noise that I get from some of my maxi jets on a wave maker. I had to take those off and forget the wave maker because it drove me crazy. The wp40 is a great addition to the other pumps that I am running.

That was the initial idea brought up which I think is the simplest way to test. Variable DC power supply is quite inexpensive. You can probably find one on Amazon for less than $10.

saltydog2, did you notice if the propeller comes to a complete stop between ramping up and down or just slow down and then speed up?

Dennis,
With the meter set at 2M in the ohms range I get 1. between the 2 terminals beside the grove on the plug. The terminal directly across from the grove gets a steady .200 to one side terminal and a constant increasing or decreasing number on the other side (depending on which is red and which is black). All that means nothing to me. I hope it gives you some insight!

You have the layout correct. This would be such an easy fix if it works and if we can find a variable 0-24v DC output. I haven't tried looking yet.

The only setting or mode where the propeller comes to a complete stop is in the W1 'pulse' mode. In W2, W3 & Else modes, it ramps up and down but never stops.

Ron If you get a chance can you post a video with all of your pumps turned off and only the WP 40 on? Maybe with the different modes to?

I am trying to understand the W1, W2, and W3 modes and how they compare to Vortech. Correct me if I am wrong. It seems W1 is a wave mode and is comparable to the Pulse Mode of Vortech and you can adjust the interval between pulse by turning the control knob to control the size of waves.

W2 and W3 modes are comparable to the Reef Crest mode of Vortech BUT the flow is not random. The control knob adjusts the interval between ramping up and ramping down only. These two modes are not wave mode but are stream modes as the pump does not pulse in these two modes.

And then there is this ELSE mode that I have no idea how it works or compares to Vortech.

Best vid I have seen Blows the fish around lol Im sold I will order a few!

This is what I was thinking about a 24V variable power supply. Will it be able to control the pump speed with lower voltage settings? $12

You hardly notice much movement in my tank without the WP40. The 2000-2200gph from the sump is delivered thru spray bars behind the rock wall. With just that pump you see no motion at all. The 2400gph of the CL is delivered thru an Ocean Motion OM4 and Revolution heads. Only 2 out of 4 heads run at any one point in time and they change directions every 60 seconds. There is movement near the revolution heads when they are on, but mostly pretty close to the head. If I did what you ask, it would look 98% the same.

OK Thanks for the info.

Exactly. On/off and the difference between the shortest to longest pulse is small. And it makes waves.

Correct. The flow always goes from very little (never stop) all the way to 4500gph. You just control the lenght. I don't see any difference between W2 and W3. The short cycle is 4 seconds and the long cycle is 12 seconds. No waves, just a ramp up and ramp down stream.

And then there is this ELSE mode that I have no idea how it works or compares to Vortech.

It does all kinds of gyrations. Up and down, sometimes fast and sometimes slow. Very random. If I could get it to max the flow at about 2-2500gph I'd like it for just stirring up the water.

I think at that price I'll buy one of the power converters and see what it does.

Hmm, that sounds like you are getting 1M between 2 terminals, 200K between 1 of those and the third, and some capacitance between the other and the third.

Well that should rule out it being a BLDC motor. Not sure what it is, but there is still the possibility that they have potted control logic right into the motor, which would lean back towards PWM or 0-10V as a possibility.

Time to read the threads on the other sites and see if anyone has investigated what this pump actually uses.

Thanks for the response, Ron. The ELSE mode, as you described, seems to be comparable to the Vortech ReefCrest Random mode which is the most popular mode preferred by Vortech users who don't want waves in their tank or don't like the pulsing noise made by the pump.

I am anxious to receive my two WP40s which were shipped out Monday. I am excited about what this pump can do. I know it is no Vortech but the performance to cost ratio is so high making such acquisition an easy decision.

[fishresponse]

I'm interested as well but way too much pump for my 18" x 24" x 24" tank. Anxious to see the wp25 in action

[SimonSKL]

I just went to Jebao website and saw this picture. The top model could be WP25 but the site doesn't identify or provide any detail. It could just be different ways to attach WP 40 to the glass.

[wakeboardgeek]

Is there an option similar to reefcrest mode on the vortechs?

Maybe you could tell us what thr 'reefcrest' mode on an MP40 is? If I had one, I probably wouldn't have bought a WP40.

See this post about the Reefcrest mode (ELSE Mode)

i do not think there is one . i believe you will not find this in the china pump for the time being

[Joserodz]

Ordered one last night...

I can't understand your sentence. Sometimes things get lost in translation. Your buying the equipment not the paper work that comes with it. Lets all play nice.
