Gianneschi Idromini domestic fresh water pump

[Deleted User YDKXO]

If someone would bother adding up at list price all the components installed on a boat, probably the conclusion would be that builders are losing money on every boat they build...

To give you some idea of OEM discount, my company buys spare Bosch hydraulic pumps from one of the manufacturers we represent. I know for a fact that the manufacturer puts a 50% mark up on the pump. We put a similar but slightly lower mark up on their price and then there is the transport cost on top. We can still sell that pump to our customers at a lower price than they can buy it for from Bosch UK at a non OEM price. The difference between OEM and non OEM prices is often crazy, not for all component suppliers but many. My guess is that Ferretti would buy that €800 pump from Gianneschi for around €300-400 or maybe less. Thats not going to make the OP feel any better

Vas that is the OEM pump from squadron 78. I'd buy it but for the fact the one I have will last 21+ years.

blimey!

and I'd buy it if I could de-rate it and run it at up to 20A, tbh I find .5KW a bit silly for two heads, two showers and a galley

It will still be working after 21 years but you might not get much sleep if someone runs a tap

Based on what I can find on the net the €800+Iva is actually a bit of steal

Most prices I can find are well over £1k

Cleghorn Waring sell that pump badged. Maybe they will offer you a deal.

I am not sure how great it is. I replaced one at 11 years. A bit young I thought.

J.,

you don't get ANY sleep if someone runs a diaphragm pump anyway, so nothing to loose there!

Jez, are you really sure that you cant get the spares anymore? Last year I bought spare parts for my 2 sea water toilet flush pumps. 27yo. They tried to sell me new pumps, but I bought the parts instead, direct from gianneci, at the price of a jabsco pump ,

 

[Whitelighter]

That's just what the engineers told me.

Thing is I don't have the model numbers at home.

if you can get the model nr and a picture, I can asc them
this was the second time I ordered parts from them, I also did a rebuild on my blacktank draining pump a few years ago.

 

[Portofino]

Mine packed up @ approx 13 y ,replaced with a suitable boggo Jabsco ,I think ?

Was noisey as well can,t say I miss it .
Thought things have moved on in 1 1/2 decades .
You can get a Jabsco in any chandelier- so no show stopper and reasonable as allready pointed out .
Feels a bit kings new suit this thread tbo

if you have 2 nice pumps installed,
I would defo try to make these run again,

we have a pair of these in Blue Angel,
and had 3 occasions that a pump failed during a holiday,
first it was a broken relay , next it was the expansion tank, and next was the pressure switch,

At the moment of a failure, you realise how handy it is, that after turning a switch and a few valves, you have fresh water again !!!
and can solve the problem later at ease...

a few weeks ago I've replaced both the expansion tanks by these new shiny SS
these Giannechi pumps are 27 yo and still running smooth with little noice.

 

[Whitelighter]

Decided to replace like with like so a new Gianneschi pump ordered. Going to make sure the new pump easily fits the old kit before ordering a second.
We still will have some redundancy as the old pump works, its just makes a noise so if we get really stuck its not the end of the world.

Thanks as usual for all thoughts etc

Right decision IMHO

B, just in case you missed Rafiki's thread on his pump, I already suggested to Hurricane the same thing that you could also do, i.e. connect them in parallel.
I explained the rationale in this post, but in hindsight I suppose that I should have explained a bit better what I meant by "in parallel".

From what you said, I guess that you have a T connection on the pipe coming from the tank, with one valve each side (or an "L" type 3-ways valve), which you can open/close, depending on which pump you wish to use.
Downstream of each pump, you might have another couple of valves, used in the same fashion (you might have none, though - they aren't strictly necessary, in fact). I also suppose that each of those pressure switches controls its own pump.

Now, what you could do with your setup instead is the following:
1) leave BOTH the intakes from the tank to each pump always open;
2) leave the respective downstream valves (if existing) also open;
3) wire each of the two pressure switches to control BOTH pumps.
4) leave both pumps electrical connection always on.

This way, what you've got is a seamless fail proof system.
Just think about it: every time either one or the other pressure switches reaches its low setting, BOTH pumps run together.
You will use BOTH expansion tanks together rather than just one at a time, therefore both pumps will run for the same time, because they need to refill double the volume.
BUT, the interval between each run will be halved AOTBE, because you are using twice the expansion tank volume.
Therefore, the wear and tear is equally distributed on both pump, exactly in the same way as you would use a single pump, switching to the other one every week (or whatever).
Besides, ANY pump can fail, as well as ANY expansion tank, or ANY pressure switch, but you will enjoy continuous service without doing anything at all.

In fact, if there's one problem of this setup, is that you might have one component failing and not even realize that (!).
Though I'm sure you don't need to learn from myself how to suck eggs, if you fancy fitting some alarm sensing such fault.
Me, I'm rather leaving that to periodical onboard checks.
The probability of having two Gianneschi pumps failing together, or one right after the other, is probably lower than being hit by a lightning anyway! :encouragement:

Surely that will double the noise?

Any updates on the ongoing quality of newer Gianneschi pumps?

This is a very old thread and based on it I purchased a new Gianneschi Ecoinox pump about 18 months ago.

I am just wondering how your pumps are going because mine suddenly became very noisy over the last week or so.

 

[PowerYachtBlog]

Gianneschi - simply put it the best pump ever made and deemed by many as Nuclear proof. I have seen fifty year units still working well.
My friends mid eighties Ferretti has a pair which still work as good as a Swiss Watch.

 

[Hurricane]

Mine has been working for 14 years.
About 7 years ago, I bought a spare (inc the pressure switches) but to date, I haven't needed the spares.

 

[Kub Cat]

Good news, maybe there is a simple solution to mine.

I spoke to the dealer today and sent photos, waiting for a reply.
