Calpeda AC Pump
|
Hi,
I am hoping someone can help me with the model number of the blue Calpeda 220vac pump used for salt water cooling of the AC units. The brass plate on my pump is corroded and I am not able to clearly see the specs. This is for a 1999/2000 model SM. Thanks. Mark Cream Puff SM #275 |

Hi Mark,
The calpeda pump on our SM2000 #330 is the CM-20 Centrifugal Pump Model BMP-35. I bought my in Holland at www.barcomarine.nl It was about €500. But they could rebuild it for €250. Hope this is helpful. Rink SM2K #330 Razor's Edge [Non-text portions of this message have been removed] |

To be more precise it is the CM-20 with article number 08.811.203 (at least at their catalogue).

Usually, when the seal starts leaking, some salt water ruins the bearing closest to the pump. If you need 1 bearing, replace both of them. If you are not sure about rebuilding the pump, take it to a water-well pump shop or a swimming pool equipment repair facility. The water-well pump shop will be much better. They can rebuild the pump for you...the bearings and seal are standard sizes. If the pump has failed, you probably need a new capacitor...see: http://groups.yahoo.com/group/amelyachtowners/photos/album/324976668/pic/58456993/view?picmode=&mode=tn&order=ordinal&start=1&count=20&dir=asc A suitable replacement can be found at most any electrical supply store. If you are looking to replace the Calpeda: Basic rule of thumb: 1 gallon per minute (GPM) is required for every 4,000 Btu's of capacity. I believe each of the A/C units are 9,000btu. 9,000 * 3 = 27,000/4,000= 6.75gal/min * 3.785=25.55liters/min * 60 = 1,532 liters/hour....6,75gal/min * 60 = 405gal/hour I rebuilt our Calpeda in Penang, Malaysia...easily found all of the parts, had a motorcycle repair shop press the new bearings on the shaft.

Thank you for the information. The pump is running a little rough and makes an occasional squeal. It has also leaked a very tiny amount of water. This leads me to the bearings and seals as a good place to start. I had never thought of a well water shop; what a great idea. I'll buy a new capacitor while I'm at it. It seems to me that this would be a good item in the spare parts bag just to keep Murphy away. Thanks again!

The squealing is the bearings...the water leak is the mechanical seal. It is a very good and very solid pump also very basic...repair it with new bearings and seal...it will last another 5-8 years...then do it again. Get the water-well shop to also check the impeller...it is metal, but may be in need of replacement, based on the age of your boat. Also, there are some drain plugs on the cast iron pump housing...check these as they tend to deteriorate. Check the check-valve on the output...it probably needs to be replaced as well.
