Itís getting harder and harder to find a recirculating pump that is 40watts supposedly the new ones convert to 80 watts while the voltage and hertz stay the same. I hate how loud they are, so Iím attempting to find a different pump to make it work.

LGís recirculating pump is 45 watts- but I believe itís DC Pump right?
Can anyone tell me if you can put a DC pump in place of a washer that had used a AC pump?
I canít find the voltage and hertz to figure out if it would be compatible.

The new LG washer recircs are DC, everything before current gen (current gen would be TurboWash 360 gen) should be AC.

No you can not fit a DC pump instead of an AC pump without much fiddeling.
A DC pump is driven like a variable speed DC motor via an inverter - or variable frequency drive sometimes called.
Just far less power hungry, thus the driving circuit is smaller and cheaper.

But you can fit basicly any AC pump that physicly fits the space.
Most recirc pumps I've seen are just the same as the drain pumps used with maybe a different duty cycle taken into account.
