Also, the mechanical pump seal and the bearings are easy to replace. 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.
Hope this helps,
