I'm trying to find out if a sihi lohy 2704 is a single stage or a 2 stage pump. Its 3hp. It does'nt have a crossover pipe like many 2 stages but it does have a deep groove in the body that is similar to a smaller sihi 2 stage that I have that does'nt have the crossover pipe either. I have looked online extensively and have'nt been able to come up with anything. Any help would be appreciated. Thanks. A little more info. The groove I'm talking about goes around the circumference of the "belly" of the pump as if to possibly separate two sections. Its a little off center.
