Pressure rated or not?

[Bullet]

How do you tell if a pump is pressure rated or not? I need to find out if the Dolphin ampmaster 4700 is pressure rated. I need it to drive a duel beckett skimmer and the pump need to be pressure rated for the best performance.

Thank-you!

I don't know for sure but the statement "Side discharge wet end, designed with latest technology, moves water extremely well at low head pressures" leads me to say no. I usually see them used in closed loops with almost zero head so I doubt it is pressure rated, but I definatley could be wrong.
