Ampmaster 3K and heat issues??

[cayecaulker]

Has anyone ever had an issue with the ampmaster 3000 raising ones water temp?

It seems strange to me. The tank water doesnt seem to be in contact with any type of heat source from the pump and yet when I turn it on (closed loop) it raises my tank temp over 1 degree F.

Any suggestions?

1*F isn't really too bad IMO.. I have one and it is pretty silent and dosen't put out too much heat.. They move alot of water for the power they use... A little heat gain is worth it I think...

NwG, your right, the economy of these pumps are great.

I like to run my tank at 80-82F so 1 degree can make a difference to me.

I just dont understand how the heat transfers to the water using the ampmaster.
I do understand how something like a mag pump can generate heat though.

Caye,

The heat is created in the winding of the motor, and in the friction of the bearings.

The shaft through the pump acts like a heat sink absorbing the heat, and transferring it through the pump housing to the impeller.

Ahhh...

Thanks Dave. It's starting to make a little sense to me now.


Are the bearings in the pump serviceable or are they sealed?

Is there anything to the service other than cleaning the impeller and its housing?

You need to keep the impeller and housing clean .

You can put a dab of very light oil at the front of the shaft. Everything else is sealed.

I recommend using a compressor and blowing out any of the areas you can reach.
