Just curious... what's the difference between FW and Ocean Motions?

I was wondering this myself. This thread started out sounding like someone had found the cure for cancer but Ocean Motions has been doing this for quite a while. I don't get it.

He seems to indicate that there are issues with the standard FW versions. Mine are custom to accommodate higher flow, has anyone else experienced any issues with custom fw's?

This is how it started out.
"After doing research and many email's back and fourth I just ordered the new Flowwolf v2.0 flow diverter.
Here is some information "
Not sure where the cure for cancer was?
I do believe the difference is clear if you are interested you can check them out at

Had a look at the oceons motions web. It looks like a far superior product. I wish I had known about a year ago. First thing is there is no actual contact between motor and water. It is magnetically driven. Flowwolf the stepper motor spindle is in contact with water. This is a potentially the weak point as if the seal wears off the motor breaks. Second thing is the rotating drum. The OM drum has 2 cut outs thus at any point there is always a port open which avoids water pressure build up. The flowwolf drum has only 1 cut out so water pressure builds up and jams the drum in one position. And since a stepper motor is used the torque is damaged. Both these issues is what has been happening to my flowwolf. If these design issues are not resolved the flowwolf will always break down.

Oh, that's why I asked since I haven't heard about issues with OM. Isn't it available in UK?

While the Ocean Motion is a nice product now, it too had to go thru problems and tweaking. OM even closed for awhile because of health reasons and just did open back up. For me I bought the Flowwolf because of the controller options along with Lucas excitement with his WELL TESTED new verson of the Flowwolf. One of the great things that come with sharing is knowledge and we now know the V2 & V3 does not work as promised.

hey when you guys say the motors are braking what are you meaning,
are they locking up and not spinning or are they burning up? the seal leaking and letting water in to the motor..
they use stepper motor in some cnc machines & rotary tables so its hard for me to think that water pressure is going to lock one up. but anything can happen.
do any of you happen to know the pressure (psi) that is being placed on the drum?
I am wondering if going to a bigger motor one with more hp&tq if that would help or some kind of gear reduction unit that would take some of the force off the motor..
has anyone been using the fwx with any luck. I would hope that something that is coating over 800 usd it would work
looks like i will be stopping my order and getting a refund after reading all of this. I emailed them all night at work and the answer i was getting was making the product sound good.. but you cant polish ****

Hello Brad,
FWX testing on final prototypes started well about a year or so. Minor adjustments were made to final production (current) model.
The main benefit from FWX over other flow diverters is the fact that the driver gets a constant feedback from the motor in terms of position, speed, acceleration and current/overcurrent so, if a stall or any other malfunction condition is detected, motor current is switched off and corresponding alarm is sent to FWX Surface and to you personally via email.
Based upon the cycles/day, firmware calculates when servicing of the device must be done. This only implies unscrewing of the motor block, taking apart the drive mechanism and lube the shaft seal. If maintenance is done on a regular basis, this is a trouble-free device.
As an example: Running the unit on X-Random mode at full speed and 1 second delay between movements gives you a 67 day maintenance schedule.
All parts taht are likely to be eroded by sand are protected, there’s no way sand or other debris can get into these critical parts. The drum is also fully detachable by hand, it's coupled to the drive mechanism, but not fixed to it. This allows for very easy inspection/cleaning.
The only consumable part is the shaft seal. There’s one installed on the device and a spare one in the box (must be replaced yearly, very easy to replace too). All US customers will have a US based contact with spares in stock: shaft seals, drums, drive mechanisms and motors.

this is an email i got from them last night
and if it helps anyone needing replacement seals they are all metric, 5x16x7 mm, double lip (VITON). try orings.com
i order head oring from them for my drag racing 2 stroke motors

The units use a stepper motor. A stepper motor works with grips which turn a shaft (push/pull effect). If for some reason the drum which is attached to the shaft gets stuck in a position the grips quickly wear out. So what happens now is the motor is still turning but the grips because they have been worn out dont turn the drum inside the flowwolf.
