Default Re: Pump overheat protection

I've only heard of one instance of the Aquamist spec pump shutting off from heat. It was the old Shurflo and it was a race car running for a constant for 20min in 40c heat. The pump was also tucked in a rear fender cavity with little airflow.

I've run many of the newer Aquatec pumps side by side, and the Aquamist spec runs much cooler and at a lower amp draw than the others. So in that case, it's better than most.

In the feedback I've gotten from the track guys, high ambient and lack of circulation seem to be the triggers to the pump running overly hot. 20 minutes at 70-80F hasn't been an issue.

Richard should be back in the office shortly and he can add his input.
