However:

...says 'Duty Cycle 30 min' per hour. Clearly they do work for longer than that ... is it worth the risk though when you could get one of these:

The head on these pumps is not much, hence my suggesting you put the tank at about the same altitude as the spindle.

I noticed this in the spec "This series have been equipped with thermal protectors in order that the motors will be able to cut off the power automatically once the motors get too hot while their working." Have you ever had a problem with them?

Quick question. I really appreciate active moderation. Are all posts delayed for moderation or does it let up when the mods are happy with you. This is not a complaint just a query.

Moderation stops after a little while yes. When I joined there wasn't moderation.

Additional big advantage pond pumps is they use a brushless motor, so there are no brushes to wear out. That may be what happened on mine.

The machine is a 600 x 1200 base. My posts are arriving out of sequence while in mod so please forgive me if you get a reply that only made sense 10 mins ago. lol

I have put up the start of my build log.
