Quietest hi flow pump for Air Conditioning

[oceanjake]

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?

I have 5 A/C and utilize 2 March Pumps. Three units one one pump and two on the other. Nice to have redundancy in case something happens while remote in the islands. March pumps are VERY quiet.

I found our Oberdorfer 104 to be quiet enough. My advice would be to call Depco pump and ask their advice. They know their stuff and carry about every pump known to man.

I have a Koolair pump as my watermaker feed pump. It’s designed primarily as a marine aircon pump. Continuous rated and super quiet. Super easy to replace pump parts.

One model is both 240/120 and 50/60Hz. Choose the sealed model. Not expensive.

www.koolairpump.com Very impressed.

Wow those koolair pumps look just like match pumps but are way better priced. I wish they had one with a larger output fitting but for $220 I think it’s worth a try. Thanks.

FWIW, Joe at Depco said today that they have sold several March pumps as replacements for the knock-off Coolaires....
