March pumps usage question

[ziggy13]

I have 2 of the standard March pumps that everyone has for homebrewing. I can't seem to find the information I'm looking for on the March or any other site.

Is there some sort of usage limit for these pumps? Can I run it for hours straight, or is there a limit? I'm going to use the pump for fly sparging but I don't want to burn the thing up. Are these things built to be ran continuously?

they are continuous usage.
I recirculate my HLT almost constantly during my brewing time to maintain temps, same with my MT with the other pump. Havent had a problem yet.
There is a link on here about the pumps, a guy (can't remember his name) that makes them answers questions.
