Re: [Amel Yacht Owners] Re: Globe Run Dry Impellers

This is intriguing. It would seem the failure rate of the pump would be less likely than the impellers. What do you do with the original mechanical pump? Leave it in place without the impeller and connect the March pump to it? Or, does the March pump connect directly to the heat exchanger?

 

Also, how can you be sure the March pump delivers enough water at full load? The impellers move a lot of water through the engine.

 

 

 

With best regards,

Hi Mark

 

The MARCH pump is a centrifugal pump used with air conditioners to pump the water around.

They come in a 230VAC version and quite a few Amel owners have mounted them in front of the ONAN and use them to pump the saltwater cooling instead of the dreaded impeller. You connect it to the AC output of the generator and saltwater in from the manifold and out to the heat exchanger.

I bought one some time ago and will eventually install it....makes sense for the Calpeda aircon pump we have too as it has no direct connection between motor ground and the saltwater thus isolating the bonding system from the AC ground.
