Nice pump, but specs are NOT as good as a WMD-30RZT Iwaki for the exact same price!!! Customaquatic has the 30RZT for 149.99.
It is a tad smaller. You would figure that considering it is not a mag drive pump. It's a direct drive.
As far as heat goes, ALL inline pump motors will get very warm. The question you should be asking is what is the output of the motor in HP. Then find the best pressure/flowrate ratio to output power. The 30RZT is rated at 1/16HP or about 47W. That's the figure people need to watch as that is how much energy a pump will heat the water (by friction). The 30RZT is also spec'd for 33' head @120gph.
Just some food for thought from a happy Iwaki owner.
