Just went through this ordeal. As you know, there isn't much choice for
100 pumps from the 'usual suspects;' it's either County or 'uprated.'
'Uprated' is a brand called 'Bastuck;' I believe they're a German
company. They do appear to have a somewhat better-designed impeller and
compared to County they turn smoother (you probably know I'm not a big
fan of County). Though otherwise a decent pump, the Bastucks have two
issues:
1) The thread for the heater return line--it's probably metric--will not
fit the 100s nifty brass valve; you're stuck using the barbed nipple
that comes with the pump. Disappointing since I've tried to keep my 100M
original as much as possible and I have a lovely, original brass valve I
can't use.
2) The pump body has a threaded plug; for god-knows-what reason the
threads are extremely loose and all but impossible to seal up. I tried
the usual teflon tape, red threadlocker, 'normal' pipe sealant and JB
Weld and none would seal even without being under pressure (the threads
are really rough). I ended up brazing the plug on one pump, but feared I
might have damaged the seal due to the heat required (oxy/acetylene) to
heat the cast iron. In desperation, I bought a County pump but the
bearings felt a bit rough. I got a tip from another Lister and sprung
for a new Bastuck pump; the lister pointed me to this (apparently) new
product from Permatex (NFI):
https://www.acehardware.com/departments/automotive-rv-and-marine/auto-tools-and-maintenance/automotive-adhesives/8008863?store=18108&gclid=Cj0KCQiAzeSdBhC4ARIsACj36uFxSKbyc_YqZGVj2GT45zIVvOr1cj-EUgn2PEmMOG3lBFpIIcC08bMaAv21EALw_wcB&gclsrc=aw.ds
This stuff worked a treat, but be sure to follow the instructions re:
cleaning and let this stuff cure for 72 hrs.
I've seen 'OEM/rebuilt' on eBay but can't vouch for them (they
apparently have an older type seal). Tom Monaco knows someone he trusts
who rebuilds them, but the guy's backlogged and Tom hasn't remembered to
let me know when he gets some done (I've already pestered him a couple
times). Any rebuilt OEM is liable to run $400 or more. Oh, and last I
checked the Bastuck were sold out; BNP had some but apparently they took
them off the shelf (possibly because of the issue with the sloppy plug).
Wanna buy my new, in-the-box County pump? FWIW, the County pump I
received has a similar barbed nipple for the return line and it appears
to be epoxied in.
