I have been researching for a possible lower energy replacement pump. The one I have was purchased as part of a package for our above ground pool. Its a 27' round AGP. The pump is a Hayward SP1520Z1EFTC, HP 2.0, SF SPL. What I would like to know is the service factor so I can see what BHP the pump really is. I have searched the www tirelessly and found nothing.
I called Hayward and was told what a replacement part no is and it is also a 2HP pump. He would not answer my question about what is the SF. I asked if this is a true 2HP he said it is a "special low head" pump so it probably has a small impeller. Reduced HP?
I then called AO Smith, they would not tell me the SF either and that their customer, Hayward, asked not to have the it printed on the label.
Does anybody have a clue what the actual HP of this pump is?
So I guess this is a marketing trick to sell lower HP pump as a 2 HP pump to uneducated pool buyers.
