Watermaker Feed Pump

Hi again,

I have another problem regarding the feed pump for the water maker. The pump is shot, it's a 220v 50hrz 50ltr (13-15 gal) per hour (max flow) magnetic drive. I can't seem to find anything like it...

I don't have 110v service to that area of the boat and I don't really want to wire it in either. I figure I have two choices; a replacement 220v pump or a 12 volt pump. If I go with a 12 volt pump it's going to have be a beefy one for sure. Has anyone got some experience with this type of setup?

Thanks for the expertise,
Meck

Re: Water Maker Feed Pump?

For 12VDC pumps look at fishwell or potable water supply. For AC voltages look at air conditioning pumps or raw water cooled refrigeration pumps.

Re: Watermaker Feed Pump ?

The same Series 5 March pumps are also available for marine air conditioning and sold in boat parts stores. They are, however, not cheap so if you can find a similar pump sold for an other purpose, like Beer, then the prices might be considerably less.

Re: Watermaker Feed Pump ?

As I understand it, the AC-5B-MD is basically the same as the AC-5C-MD, but with the 5B's Polysulfone and Stainless Steel replacing the 5C's Polypropylene and Ceramic Magnet for the Cover, Impeller Assembly, and Rear Housing components.

Not so cheap - AC-5C-MD @ $328.00

Hey, thanks everybody. I found the March Pump Magnetic Drive Pump AC-5C-MD at starmarinedepot.com for $260, the 115v version was a bit less. Thats the best price I found and was pretty much what I was expecting to spend.. Thanks again
