My sink pump gushes water from the top seal and I assume that new seals are not available. Does anyone know where a replacement pump can be sourced and how the old one is removed from the sink?
Thanks, Keith

Hi Keith.

The bad news is that the Brass Whale 1 1/2" bilge pump that is used on many Contessas as a sink waste pump became obsolete in the 1980's even though it works very well.

The good news is that the spares kits are still available from W.J. Gilmore, 24 Springvale Road, Ballywalter, Co Down, BT22 2RS. We bought one for about fifteen quid earlier this year. We found the disassembly/assembly of the pump straightforward although you have to remove it from the boat first. If you have any queries please get back to us.

Thanks Mark/Liz

The web site does not work but I have found a telephone number W.J.Gilmore tel: 0284 275 8865 begin_of_the_skype_highlighting              0284 275 8865      end_of_the_skype_highlighting and will call them.
I need to get the handle off the pump shaft to release it from the sink but can't see any obvious fixing - does it unscrew? - As these things are rare I don't want to use too much force and break it.

regards, Keith

Hi Keith,

Yes the top black plastic handle unscrews from the brass shaft. You may need to use a mole wrench protected with a suitable cloth on the shaft to hold it steady whilst you unscrew the handle. The whole assembly then needs to be removed from the galley before anything else is taken apart.

I'm not sure that the number is right -  the company has recently moved which was why the website was not working - you may need to write.

Hi I changed the shaft to a metric size and fitted standard seals, machined the bearing to suit, I didn't even think about a repair kit. I really pleased with it, so much pleasure in pumping out the sink

The telephone number for William Gilmore was OK and he has promised to send the seals including the shaft seal. Thank you all for your help.Wink

I recently had the same problem and Mr Gilmore is indeed the correct contact - he sent me an original Spares kit and the pump now works like new.   the number given earlier looks correct.  Any issues making contact let me know and i shall look back in my records.

Hi, I'm trying to source the same rubber gasket but Mr Gilmore's details no longer seem valid, i've tried several times and the number just rings out. 

Does anyone have up to date contact details?

Failing that there is a company (FPE Limited) that makes the part but they need more details about the size etc. of the gasket and i'm currently a long way from the boat, does anyone have spec for this gasket? 

Thanks a lot

I'm having the same problem with contacting Mr Gilmore.  I did get through last year and he asked me to send an e mail which I did, but then he never got back to me.  I have the pump here at home and will contact Fluid Power after the week-end, and send them the seals to see if they can match them.  If they can I will post details as I suspect they might do quite a brisk trade! Thanks for tracking down a firm that might be able to help.

Best wishes,

Hi  That will not be cheap.
A new shaft and off the shelf seal will fix it. very easy to do. I don't mind

Alternately, fit a macerator pump and eliminate the potential for blockage by food waste and the endless pumping to empty the tank for the winter!Smile

Hi Michel

I'm sure I can put a kit together. The shaft is just a standard bit of bar with the threads put on the end and the seals are off the shelf.

Your right the pump works well and also it is correct for the Contessa 32

I will supply a drawing of what is required for the plastic top. so a local machine shop can do it for you.

My email address is available from the forum. Please let me have an email address for you.

I will only charge the cost of materials, This forum is not for profit. I agree with the principal and enjoy helping other Contessa owners.

Fluid Power can supply a suitable seal:
2 Kellow Road
Co Durham
01325 282732
The replacement is not as deep as the original but can be packed out and works fine.   Sorry I have mislaid the ref number - send the old one and they will sort it out. 
Minimum charge, I think you have to buy two.

Yes I concidered that when sorting mine, but the biggist problem is the plastic cap. It's also the bush and seal housing, and the bush wears then the shaft can move side to side and the seal is unable to accept the side movement as you pump out.  That is why I went up a size.

I sent Fluid Power the seal at the top of the pump handle and the seal at the bottom of the plunger along with the bush above the top seal. The new seal at the bottom was just a bit too big to fit back into the pump, but the seal at the top works fine.  They didn't seem to be able to replace the bush though.  I have re-assembled the pump with the new top seal and it seems not to be leaking. If it still holding after our summer cruise then I will be more than satisfied!   The person at Fluid Power I spoke to said he'd e mailed me with a price, but the e mail never got through. It was all, however, quickly sorted out on the phone when I called a second time.

I sent FPE my old top seal on Monday, they machined 4 new ones on Tuesday and I got them back Wednesday.  It looks identical and also more substantial.  Once fitted it turned my weak leaky pump into a water tight high pressure weapon.  Will have to see how it lasts but first impressions are good.
I have a couple of spares.  They charged me £3 each if anyone wants one let me know and for cost plus p&p i'll send on.  Very easy to fit once you get the pump out of situ.

Just as an update some years later Eddie Gilmore has just supplied me with an original Whale service kit for this pump which has transformed it's performance back to original.

Mr Gilmore's up to date contact details are;
07707 030 573
28 Springvale Road
County Down
BT22 2RS

I texted him initially and then after a quick exchange of messages and sending him £20 the service kit arrived within a few days
