Joel,
What does it depend on? Will some pumps run on a higher frequency better than others? I don't know much about electric motors in general, but from I have learned is that frequency is crucial to how they run/ how fast they spin. Voltage isn't so much of an issue though...
TIA!
Cheers,
Jim

Depends on the insulation, packing, basically the quality of construction around the windings whether it will handle it or not. If it can't, it'll be obvious after about an hour. I think the skimmer design is still interesting if another pump can be fitted in there.
Well we will find out in about 10 days.<a href=showthread.php?s=&postid=11822640#post11822640 target=_blank>Originally posted</a> by jimdogg187
I don't think you can successfully run a pump designed for 50Hz on a 60Hz frequency with a converter....
The voltage will convert over, but the motor will have difficulty running on higher the US frequency.
I could be wrong though

From one with a PhD in electrical engineering:
Only testing will find out if the pump is designed with a safety factor enough to take the additional load. I have found that many centrifugal pump manufacturers use a smaller capacity motor than
they should, taking advantage of the fact that today's barnishes used to insulate the windings are a lot better.
Not sure what it means exactly but I understand the part that each pump model is manufactured a bit differently (as in, Quiet One vs. Sicce, for example). Just have to test and see.

So I'll find out if its running ok in a few hours, thats cool. I agree with you about the design of the skimmer running with another pump if the original doesn't work. It only cost $172 dollars with the voltage converter and shipping. So its not like I'm breaking the bank:smokin:
I got the one pictured on the 9th post of this thread
The other one has the picture with the nasty skim but I think this one is designed better. So far the transaction has been good. I've received about 4 replies to emails. Sometimes you can't even get that from companies here in the states. Don't get me wrong it takes me a while to decipher what they are saying but all seems OK.
If you look at the picture on the 9th post you can clearly tell that its the BM100 because the 100 and the 99 are completely different. They charged me 39.99 for shipping because I had originally ordered the BM99 but I changed it to the 100. Four dollars is no biggie. I payed 119.99 BM100
39.99 shipping
12.00 voltage converter
---------
$171.98 total
I tried posting a link to the ebay site and it didn't work. Thats why I just said that I got the one like post 9.
