the difference is the irrigation pump is not turning at high RPM constantly running high temperatures...

But Im smiling that we are comparing a high tech racing superbike with a simple irrigation system. ..... so all the bikes that are not leaking coolant must faulty and the owners should take them into dealers for a repair :mad:

Dewatering on the mines the pumps run flat out without any leaks, there massive too needed a crane to lift them.

I don't know of many water pumps , slurry pumps, de watering pumps that run high rpm's.....please enlighten us :confused: unless you ride your bike at 2000 rpm and think it's reving high :confused:

The weight of a pump does not determine its rev range .........your post makes no contribution........

Nor does the engine rpm that its attached to. It is gear driven after all so
who knows what ratio of pump to crank revolutions exist.

And even then, its not shaft rpm that is really important, more about the relationship between shaft size and rpm, ie the surface speed difference between
the rotating and static parts and the friction coefficients of the seal materials.

The shaft on the water pump is about 6mm so surface area is not that big? but im certain it gets hot as hell??

I have yest to see a water pump running 10K but stand to be corrected....cavitation comes to mind?

I have just had some pics sent to me by my wife who informs me my 1299 is having a period again..:mad: water all over the floor, and the bike has not been running, this is after its been standing for almost 3 weeks now.

Pics suggest coolant is leaking from the thermostat housing ..I will have to look at this when I return.

I read in one of the threads guys were suggesting bikes do leak as the atmospheric pressure moves, they were referring to cool bikes that were just standing? anyone comment on this?
 
Even if the pump is geared down, it would have to be capable of pushing enough coolant around at idle , so it would still spin 5-6000 rpm at least when getting towards redline?
The shaft temp would cap out no more than the coolant temp. Your bike starting to sound like it could be lemon juice on the floor ?

My 899 dribbles a bit here and there. Planning on doing the magnesium clutch side in a few months and am going to pull the water pump and seal and see if one of my suppliers through work can source a viton seal. Not sure what the compound of the factory seal is does anyone know for sure?

I cant find it anymore, but there was somebody on here who pulled the OEM waterpump apart and replaced the seals for something different. There even was a pic of the old seal and the new replacement and the OEM seal was very thin and soft.

thanks photobucket....

Not so sure about the ...... posts? That said forgive me I'm not siting in a warm internet cafe with wi fi
We have limited internet access very slow and only 3 days a week for less than 20 mins per guy if that,..

Halo how do I post pics using an iPhone, it's the only device I have, also could you post an exploded view of the thermostat housing for me?

Just want to get my head around it
 
Put pictures on dropbox.....link from there.

No exploded view and threw out my leaking one, its two parts top and bottom with a seal in between made out of cheap plastic.
