Works great!

I replaced an electric pump with this AODD pump. Even though I had to get an air compressor also. In the long run it is a way better pump that moves product and I don't need to worry about the impeller getting bound up.

I definitely recommend. This AODD pump is very reliable for the price. I use this transfer pump all day long for very hot liquids and have yet to deal with any leaking. I will continue to go with this one. And I will buy more if I need.
