    Week into our holiday, out at Windorah,relaxing camped at Cooper ck,bloody nice spot,get the call my Mother had a stroke.
    Unfortunately that was the end of her.She was 86 so not a bad innings.
    Been sorting out stuff since we got back,13 hour drive straight through, one stop at Maccas and fuel at Roma.

    I have 3 brothers so we are all in it, and get on reasonably well so all is going reasonably smoothly so far.

    Been through this 3 times before, hopefully never again.

    Weird isn't it? I have a a Davey Yellow centrif. which pumps from a 100gal. collection tank over to a Big Concrete tank. Sometimes I have forgotten about it & left it running on MT while otherwise engaged. Each time that happens I expect the seal to let go but like yours, it still keeps on ploddin'. I think it is a Carbon nose & spring seal, but still it keeps on going. Fingers crossed.

    I set a Kitchen Timer (which I carry in my jacket pocket) on it these days just in case.

    Grundfoss have been the leaders in mechanical pump seals for years, along with their quality pumps. Silicon Carbide ceramic based seals will stand heat a lot better than just plain carbon types. Just the humidity in a system will help them dissipate heat as well. Their only drawback is that they are brittle and need care if replacing one.

    We find that usually if the tower or for that matter chilled water system runs out of water, there is enough water left in the cavitating pump to look after the seal.
    I cant remember last time we had a seal fail, and in the last few years we have had quite a few towers run out of water,as well as chilled water systems.One site had two towers run dry 3 times a few months ago, although on that particular site once the chillers go out on HP,the condenser water pumps also shut off.

    I guess it would depend if the Discharge pipe was Vertical or Horizontal.

    Vertical would mean fluid already pumped would be available still in the discharge line for "cavitation", & Horizontal, it would be self-draining & therefore not available.


    Or am I talking bollocks?
