I have a Cal Pump 1200 GPH that's been running 24/7 for 7 years now without
a single problem. They make larger pumps also.

I can't believe it, but after looking at the shaft material, I'm not
surprised. It appears to be a flimsy piece of plastic, so I suspect that
the
torque of the motor, combined with any sort of load, results in breakage.

I'm hoping the place that sold it to me will replace it today without too
much hassle.

Anyone else having problems with this pump?
