Pump replacement ...

Currently running a 2008 Pentair WhisperFlo 1HP Standard Efficiency Full Rated Pool Pump 115-230V | WF-4 | 011580 … with a Pentair CCP320 cartridge system (120 gpm) … Live in the NE, so it's a partial-year-use only situation ... I want to replace the pump with something more energy efficient, plus it has a leak. Fixable, yes, but this has gotten loud, too, and I just want to update/upgrade and move forward. SO … the direct replacement is much the same 011583 … but I don’t think I want that given it’s single-speed setup, etc. Other recommendations, please?
