WOW!....I was considering bidding on this today, as it is nicer condition than mine.
The bid went all the way to $281.10 with shipping!.....Now just cleaning Mine up sounds like a better plan

I suspect the piston seal(s) were oiled leather, and may well be long gone or petrified. I’m thinking that like a hand pump, once you get the cylinder bore nice and slick, it wouldn’t take much to fabricate seals from polyethylene. My dad rebuilt a well pump and cut seals out of cool whip bowl lids.
No leather piston or seal, just a clack-valve in the piston.
A ball bearing as a non return valve and a piston with holes and a round T shaped valve that sits inside the piston

Dennis, I am interested in pictures of the piston of the pump. Actually of the whole inner workings. I have followed your report on the construction of the Pericaud, but I have not seen detailed pictures of the piston and the non-return device. Or did something pass me by? My old head is a bit sloppy sometimes.
Solder won´t stick...
But if screwed tightly down to a neat wooden base, forcing the broken "leg" back in place (should it break, it can be glued back with JB Weld), it wouldn´t worry me much, as i doesn´t look like dezinc to me, more like abuse.
Pump #3 with (cracked base) sold for $187.50 plus shipping. I had no idea the market was this Hot on these!

The non return valve is a ball bearing at the bottom 0f the column that rest in a bevel edged hole in the base .
The piston is hollow with 5 holes in the head of it.
1 is in the center and 4 around that .
A T shaped piece .( the leg is a loose fit in the center hole .
The top of the T is a disc that covers the other four holes .)
The T drops in to the piston and moves up when the piston goes down thus allowing water through
The piston and around the piston rod and when the piston comes up the T valve (seals?? ) the four holes .
The piston rod connects to the piston via a wrist pin allowing movement .
I will chicken scratch some pictures later
Hi Dennis,
Thank you for the detailed description of the setup and function. I can now get a better picture.
(and I believe one is listed as cracked in the base)
