I believe it is either a five or seven horse motor running on 220v. I believe the pipe coming out of the casing is two inch. Im not sure what the casing size is but it is very good cold water and never runs dry. I wish that I could have afforded more water but each size bigger got to be crazy expensive. I had looked at a twnety horse moter with a six inch pipe but it was just too expensive. The twenty horse motor would have been able to fill the pond. The setup I have now just keeps it at the level I have when I turn it on.
