Mark,
My March pump puts out 951 GPH @50 hz.  True, this is less than Calpeda.  I loosely used Bill Rouse's formula of 1 GPM for every 4,000 BTU which says I need min 405 GPH. I have more than double using that metric.  In any event all works well for over a year.   The pump I replaced was a March LC-5C-MD (original Calpeda failed ten years ago) which had a slightly lower capacity than current unit:  54.8 LPM vs. 60 LPM.   It lasted nearly nine years.  Two of three AC's are original and run well.  Aft unit was replaced with Marine Air 10K unit as previous owner wanted to be frozen.

I’m not sure that the AC model has sufficient flow ratings when compared to the TE model. Keep in mind that when plugged into 50 Hz the pump operates about 10% lower. The TE model more closely matched the original Calpeda’s specs.

Hi Oliver

We replaced original pump with March.  It cost much less than Italian pump and has an excellent reputation.   See below

Oliver,

 

We replaced the expensive Italian Calpeda pump installed by Amel with this: https://www.coastalclimatecontrol.com/index.php/product-catalog/product/260-march-1500-gph-115-230v.html. It works much better than the Calpeda (very old technology and expensive parts - also not suitable to ground to the bonding system). The March pump doesn't need to connect the housing to the bonding system since it is plastic where seawater touches (you will need to connect to the ground). You can probably get the pump cheaper if you shop other than coastal climate: http://www.ebay.com/itm/March-pump-TE-5-5C-MD-1-Phase-115-230V-TEFC-/361876817634?hash=item54418a06e2:g:rMkAAOxygPtSyFqm

 

If you wish to replace with the same pump (after all, ours lasted 15 years) Coastal Climate is the USA dealer: https://www.coastalclimatecontrol.com/index.php/water-pumps.html  They are the people who recommended the March pump to me and it has worked well for 2+ years. It was an easy swap as the foot print and hoses are similar. You need to jump the wiring to make it 220v (instructions are included – very easy to do)

 

 

 

With best regards,

 

Mark

Hi everybody!

 

We have the original Calpeda BCM20E AC pump on board of our 13 year old SM 2000. We would like to buy a spare pump as long as the boat is in the US, where it is easy and cheaper to buy. 

 

Has anyone experience with the march AC-5C-MD AC pump. It runs 50 or 60 hertz and it has an magnetic drive, what sounds interesting. The inlet connection is 1 inch and the outlet is 1/2  inch would this fit?
