Re: Dripless seal

I would not change anything and stay with the Teflon packing. When I had a packing gland, al I wanted was one that doesnít overheat when fastened so that there is no drip and this is exactly what the Teflon packing material delivers.

I would not be worried about scoring on shaft unless the gland is tightened too far.

Re: Dripless seal

Even if the shaft scores, who cares if the Teflon keeps it from leaking.

With a dripless there is the possibility of crevice corrosion where the rotor attaches to the shaft, or scoring in the case of the Volvo seal. No free lunch

I Keep coming back to that, that is there isnít anything to fix.
Where the scoring can come from is sand or silt imbedded in the packing. I doubt even old school flax scored shafts without a little assistance from sand etc.
You can tolerate quite a lot actually by lengthening the hose and moving the packing up the shaft and let it score a new section.
Still, the thought of installing something and forgetting about it for a decade is tempting.
It ran hot when first installed, maybe an hour or so, but I backed off of it and itís not even running warm since then.
Iíve not even adjusted it since that first time. Itís a real pain to adjust.
