No. You need a bronze pump.
The three-speed technology is designed to reduce noise & power consumption. The best way for you to set the pump depends on what you will be using it for, but general instructions can be found in the manual: http://s3.pexsupply.com/manuals/1293801581942/42920_PROD_FILE.pdf
High speed pumps more g.p.m. and uses more wattage. You can adjust to your application. This way it can replace several different models of pumps by setting it to what works best at the lowest wattage.
The answer depends on how many zone valves are on the loops. The pump may be too small if there is only one.
