Return Pump For 180

[freshwater]

Should I get a Velocity t4 pump for my return or a MD40RLXT Japanese Motored Iwaki Water Pump for my return on a 180 gallon tank. I am looking for a farely quiet pump since it will be going in a dentist office and I am looking for around 1200 gph since there are 2 1" drains. Or are there any other pumps people would recommend?

Iwaki's are very good reliable pumps in my experience. I also hear a lot of my larger US bretheren talkin about I think the name is Blue One pumps... No personal experience with them, but I hear they're good
