The new IntelliFlo i1 011059 230V variable speed pool pump up to 1HP has a unique hydraulic platform that was specifically developed for compliance with certain flow rate regulations in specific geographical areas. In some regions, pool owners with smaller plumbing diameters may face regulations that restrict the rate of flow on replacement pumps in certain applications, thereby precluding them from using some of today's most energy-efficient pump models. The IntelliFlo i1 pool pump provides all the great features that have made our standard IntelliFlo^® pumps the best-selling industry standard, but is engineered to limit the flow to the equivalent of a 1 hp WhisperFlo^® pump. Furthermore, IntelliFlo i1 pool pump has a max amp rating of 7 amps, which helps make retrofits easier in applications limited by an existing wire gauge size.
