    How do you balance the pin wheel so that it does not damage the bearings??

    by threading evenly, and my orp 3000 on ts 3 is quieter than the pin wheel. ps what bearings other than two rubber goodies and plastic washer on each side of impeller? ps do people balance enkamat impellers? like the factory made one for my aquamedic skimmer?

    On ceramic shafts/bearings unbalanced impellers ware uneven causing seizures of the impeller. This causes the stator to over heat and burn out.

    Many years ago Aqua medic patented the pin wheel and Deltec the needle wheel. Yes we tried the above mod only to find that it worked very well for a few months until disaster.

    So from my experiences please do this mod with forewarning that it will go wrong sometime soon.

    the total weight difference is about 2.5 grams total . if you look at my aquamedic impeller which is a combo of enkamat and two sides of a pin wheel there is no way in hell that it
    is any more balanced than this. weight or any other wise.

    Guys, enjoy the discussion but keep personal "attacks" out of it or take it to PM we will not tolerate that on the open forum

    I don't think this will cause any problems. I've been running my skimmer for 7 months now with the enkemat mod and it is silent and still working perfectly.

    The bearings at the end of the impeller shaft. Some impellers have fixed shafts that run on ceramic bearings at each end of the impeller shaft. Others have shafts that are secured at each end by a rubber retainer and the bearing/bush is the center of the impeller. In all cases from my experience these give issues after time if the impeller is unbalanced or the air restriction to great.

    Uhhmm first off the pic is of a needle wheel as used by Aquamedic and Deltec used the pin wheel. I converted 2 needle wheel pumps as above pic with Enkomat about 4yrs ago and they still running strong today, never missed a beat. I have just done the enkomat conversion on a AM 5000 Twin and expect no problems even with ceramic shafts.

    if we look at the standard OTP pnwheels they are notorius for going out of balance. I experienced 3 myself with different pumps and i am sure there have been others on the forum who experienecd it as well. skimmer pump starts making a noise and once u change it, its all sorted. Great video Nemos
