Whale Gulper 220 How to dismantle & replace gear?

[Franziska]

Hi there,

today my Gulper 220 shower drain pump failed on me. Apparently the white gearwheel inside got stripped of some teeth.
The pump is in daily use for about a year and lifts only 1m. The lines are not clogged up. Guess its "normal ??????" wear.

I found info on the web that some people got replacement parts, but could find noone who actually explains how to take off the white gearwheel.

Please see the image here.

I wonder if

1)
I should remove the electric motor & wormdrive (how??)
2)
I should hammer out the bolt in the white gearwheel in the direction of the wormdrive
3)
if I should hammer out the bolt in the white gearwheel in the opposite direction of the wormdrive

Once its off, any idea where I could get a bronze replacement gearwheel in Holland?
I am hesitant to use a plastic one again.
Still if anyone has the correct email of where I can get a plastic replacement that would be helpful too.

Many thanks,

Fran

Fran,

Not a clue. However, I have a few of these pumps and I have talked directly to Whale to get service parts. I'd give them a call. I found them helpful.

I just replaced a diaphragm in one of these, in constant heavy use as a gray water pump for 13 years and not a lick of trouble; one of the few items of gear on the boat which has been so trouble-free.

I think it's odd and troubling that it would eat a gear. I would replace the whole pump if I were you.

Hi,

actually everything except the gearwheel is fine. I researched it and that seems to be the only piece which fails on very few of these pumps. Apart from usual replacement parts, such as diaphragms.

I would hate it to have to throw away an expensive pump, just because a small plastic gear fails.

Thats why I need a pointer how to get the part out and where to find a suitable replacement (preferably bronze). I am in touch with Whale, but have not heard back yet.

N8N8,

Fran

Whale is going to be the right place.

Your post reminded me to order a whole spare pump, which I just did.

Really sucks when things like this fail far from civilization.

I wasted a whole day in a magical place I could have been exploring trying to find a spares kit for this pump, then tore the whole boat apart looking for the spares kit I knew I had but couldn't find

Over the winter I'm going to have a comprehensive review of my spares inventory. A big part of having fun while cruising is avoiding spending the entire time fixing the boat. You can't prevent the failures, but you CAN make sure you have the proper parts and tools on board. With the right parts and tools to hand, properly organized and stored where you can find them (!), many of these failures are not a problem.

It would great if someone could post a list of spares one should carry. I realize different vessels, different spares, but a good general one would be wonderful since I'm a newbie and could use one. Thanks all

I don't have it handy to check but I think Nigel Calder has a recommended spares list in his cruising boat book. I know one of his books has recommended list of tools. In any case, it's a place to start and they are both good books anyway.

Dock head, I have a spare pump with nitril innards ( for diesel xfer) on the big boat. I'm trying to standardize on these guys.

Thank you, will use info.

Hello,

I could not find a replacement part at all not even from the manufacturer.
I can sell you a new 3D printed gear wheel for the price of £3GBP + postage.

The gear works well on my whale Gulper IC . You will have to try it on your pump.

Ali

Any chance I could get the stl? I've been looking around for a replacement...

Necroposting! Almost 10 years ago (!), I wrote in this thread about ordering a spare 220 Gulper. Funny, just last weekend I finally installed it.


The by then 23 year old original pump finally burned up a bearing or something and started screaming. That's after a lot of work, as it pumps out one of my showers, one of my sinks, kitchen, washing machine. A lot of pumping. I had replaced the diaphragm a couple of times during a period when I was putting chlorine down the system before I figured out that it destroyed these diaphragms. After ceasing this practice, the diaphragm failures stopped.


The gears -- metal, not nitride -- were still good.



This is a very good pump.
