I currently have a single speed 1 HP super pump running at 115V that I would like to convert to dual speed or variable speed for electricity cost savings. The wet end of the pump is in good shape, so I would only be looking for a replacement motor. Is there a replacement DS or VS motor that exists in a similar HP rating that can be used with 115V? I haven't found any on the Hayward site or Inyopools, but the amount of options makes it a bit overwhelming. I would really rather not convert to 230V unless I really have to. Thanks!
