I had one just like it on my Hans Christian. Actually, I had two. One was for the pumpout of the holding tank
and the other was for the emergency
manual bilge pump
. I rebuilt both while I had the Hans Christian.
I was told that these pumps were built in Taiwan
by duplicating big Whales pumps. Sure enough, I was able to get rebuild
kits that were nearly identical to the original parts
. I took one apart and measured the diaphragm
and ordered the kit that had one of the same size. It turned out that the other parts fitted as well.
Caution - We nearly lost
our boat when one of the diaphragms split. We were healed over for a long time and the through hull
seacock was not closed. Water
came in through the pump for a long time before I discovered the problem. After that, I made sure that the seacock was closed. Getting the new diaphragm
in the Bahamas
was not easy.
These brass pumps will last forever if you can get the parts. On mine, there were no identifying model numbers.
