Also, I can't find a higher output for this "Series 5" March pump.
Additionally, the AC-5C-MD Magnetic Drive Pump
(March Pump recommended by Veco and Coastal Climate Control) is rated by March at 17GPM or 1,020GPH. This may be the reason they recommend this pump.
I believe the output is too low on the AC-5C-MD, and suggest that you keep searching.

Agree, but I wonder why Veco (manufacturer of the Climma AC) doesn't recommend this pump, rather another March pump. Possibly cost, because it is at least 50% more? As far as I am concerned, the March LC-5C-MD is the best pump to use for the AC. The only question I have, is there one that is 1200-1500. The first chance I get, I'll ask Veco why they don't recommend this pump. I'll let you know.
Here is an example of a March liquid cooled pump
I had the pump in my hands in St Maarten. It is totally encapsulated in what appears to be some form of epoxy and NOT PAINT and there is no way for it to rust.
There are 2 copper pipes coming from the pump section to cool the motor. I would however get the next size larger to get maximum water volume.

I believe this is the wat to go.
I was curious and looked at the March info. I believe the 'AC' designation refers to an open style motor that should not be exposed to the possibility of water getting on the motor. The 'CP' designator is an open drip proof motor that would tolerate exposure to some drippage (?) from above. They also have TEFC motors available for some direct exposure to water. However, I think all these motors except the 'LC' submersible variety are standard carbon steel motor housings with some form of a painted finish that apparently does not tolerate a salt air or humid environment i.e. they all will show surface rust at some time. Good luck with your preventative maintenance project.
