Kev is still a youngster though Abes (got stuff in my freezer older than him) so a lump of old iron will not trouble him much! Smile
A nice pump though, the only Pearns pumps that I have seen are the small 'boxy' ones similar in size to the Lister domestic's.

not yet mr jones
still thought it wasnt working just as it should so stripped the lower cast caps,
and brass so i thought drain tap as it turned out to be a air suction valve nothing comes out just sucks air in ,to start the phospher bronze valve off,opening and closing to start lifting the water "weird but true "
and the 4" diameter bronze poppet valves were not sitting on the seats with chunks of rust and stones in them.
now it pumps water fast as duck and if i turn the tap off ,it holds pressure for over 30 mins in the top end 2x poppets just the piston needs gland seals removing and cleaning and the refitting and oiling up before the next test

as for the paint job will give it all a good soaking and rub down ,
and see what lies beneath the black cruddy greese and sump oil that has been on it since the summer of 1973 when it was last used and put back in the shed well atleast that far back from his memory as he just got a new PETTER PAZ1 and used it on the pump to break it in. when were paz1 made from and too ,for a better dating reference ,

stu mate
you are getting to now the way i work well now mate
and it maybe staying as is on the paint side
will see after she has a bath and a good scrubb down
thinking to leave as is as the paint is old but not as old as the pump was last painted from his memory 1950-60s when his dad restored it
good old sump oil and grease baths when not in use , and as always does a good preserving job
just bloody nightmare to get off my hands and tools ive used a carryer bag of rags so far on it and its far from clean yet
the bearings and piston well the parts the oily greese cant get to were well seized but not rooten "bonus for me
glad to help your old bones, and give them a lay down for you mate Very Happy lol! lol!

Good to hear that the oil/grease covering has saved such a great looking pump, has to be worth a few bags of rags in my book, you should have took it down the car wash and pressure washed it, at night so no one could see all the gunk on it. Laughing Laughing Laughing
Kev just a thought and not a place I've been to, but would the Manchester industrial museum be able to help you date it in any way, as in the year the company started, closed, what was built there etc. They may have some old records or books on the firm.

well the pump has had a second complete stripe down and all the poppet valves polished up and seats to match and another pound or two of rust and sludge removed from the insides, the piston has had a light deburing and all over 200 sand paper degaze, and a single new ring of 1/2"x1/2" gland has been fitted as i found a peice in my steam engine parts boxes , it now holds pressure overnight at all pressurized side,
but with a small leakout at the piston on the low pressure side, but the 2nd and 3rd valves seal it up tight and will blast water out with out turning it over,
3 days later when i open the tap , so well happy with the monster, thinking i need to get a presssure gauge for it and see what the output is ,as it blast out water at about 20 rpm , so woried if it was designed for steam powering and one of there most popular pumps were for boiler supply feed pumps ?????
and with the amount of one way stop valves ,and lowspeed pressure ????????

im now worried that the amanco maybe to fast rpm wise for the output as it will hydrulic and stop turning at hand speed if the tap is half one affraid affraid
so for the maths me help please
amanco 450 rpm with a 6" pulley going to the pump with a 21" pulley with my maths i get it to arround 125-130 rpm at the pump ??

2.5" bore x 5.5" stroke what is the water capacity per stroke or min hour ??????
i think the pump displaces 500ml per 1x revolution so i get 60 litres per min 500+ gallons per hour
anyone that can do maths better than my divy maths head please do dig in
thanks kev

Did you try using this calculator to work it out Kev?

http://www.csgnetwork.com/pulleybeltcalc.html

Maybe Neville can help he put the link up as he used it to work out his pulley sizes.
