water pump and electicity Hz...

[boyohboy2]

Would the different Hz (frequency) creats problem when running the pump?
I just got a Seio that is 220V/50Hz,... with a stepup transformer, now running here in Canada 110V/60Hz (ie transformer setup the voltage to 220V/60Hz).
For some reason I can only run it at the lowest flow setting (still alot of flow tho), once I turn the control up, the impeller will just shake and makes very little flow. Duno if it's the problem of the Hz or the pump itself. Forgot to "test" it when I was still oversea with the 220V/50Hz electricity. Will the 10Hz different create problem? Maybe since the Hz is too fast, when running at the higher flow setting of, the Seio impeller/motor just cant' handle it?! Lower flow setting is ok coz it's less load on the motor?!

Well on a good side, at least I got it for less than 1/2 the price so no complain, the flow is enough for me already at the lowest setting anyway... but want to try how much flow is the highest flow

Any electrician here?

Where I live we have 115V 50hz power and my sequence Dart pump is 115V 60hz. While it runs fine on 50hz it is about 20% less flow then when I test it on my 60hz Standby Generator.

In your case I think that you might burn out the pump on 60Hz power as you are overloading the pump. You might get away with it on low setting but I would not try the High if I was you.

Frequency adjusts the speed of the motor.

You could either try contacting Taam about getting a new impeller meant for 60 hz. Or you can get a variable frequency controller, which are very expensive.

I agree about the Frequency adjusting the speed, I just don't figure how a new Impeller is going to help! Even if it has a greater pitch and slows down the RPM's it does not change the amount of current that the coil windings are receiving.

I've heard of someone's pump running cause it was the wrong frequency and all they had to do was replace the impeller.

One thing I want to know is will the higher Hz "overload" the pump at all? I mean if it's overly too fast, the the impeller's design may not be able to turn. But in terms of electricity goes, the voltage & current isn't related to the Hz, right?

The "high" and "low" flow setting on the Seio isn't really much other than restricting the input slots... so either way isn't affecting the current/Hz/etc of the pump I think.

 

[RobbyG]

Yes the current is changed by the frequency. By upping the Freq/HZ you will be increasing current flow through the coil.
I would take a guess that the motor will burn out if run on 60hz.
It all depends on how much tolerance was added, but overtime it will certainly do damage.
