I’m looking for a quieter replacement for my Dayton centrifugal pump. The requirements are as follows: 230v. Quiet. 1” input and output (could adapt this if needed). Enough flow for the 5 AC units I have aboard. Current pump is 60gpm but is overkill. I’ve used March pumps in the past on smaller boats and they were whisper quiet. I don’t see one to meet the specs above though. Ideas? Suggestions?
