Some are street capable but most are strip only. Here is one that will work on the street:

Meziere lists the pump as having 2000-3000 hours of life. This is 3 years of 2 hours per day use. These things are not cheap. IT is cool on some cars to not have the belt drive to the water pump.

Before you buy call the manufacturer....not the person selling it. Ask if the thing is useable on the street and ask the life rating....
