I collect these pumps in Australia and have the original casting moulds circa 1940's, parts here are easy to buy. I will endeavor to put a video on showing the overhaul process. they run well with a 1425rpm 1/3 hp motor with a 2" pulley which takes it to about 400rpm on a standard cast wheel
it is a easy pump to rebuild the piston comes out just unscrew it with a flat top and the two leather cups are botled together facing oppsited of each other
hi i have the same pump but in better shape , pump was rebilt but do to my stupid fault the out put line got plug and the pump blew the leathers so got to spend 14 dollards to fit it haha will put a pressure switch on it next time
These are good piston pumps, here in New Zealand we use Davies Pumps which are very similar to the one you have there, i have a couple of other videos of pumps i fix and sell..plus parts here are easy to get for these pumps..i think your pump is exactly the same..i fix them with electric and petrol motors..cheers.
thats cool! i didnt know you went to school to be an electrician. im in my last year of an electrical program. i like it alot!
and my dad got me 2 antique compressors for christmas. 1 has its original westinghouse 1/2hp repulshion start induction motor. that thing runs like brand new and is in awsome shape!!
that GE is a nice little motor, i have a couple split phase versions of that. i also have a 1/2hp capacitor start one on an old Goulds jet pump.
This GE is split phase, should have mentioned that in the video. I would like to find a Repulshion Start Motor, I think that is an interesting concept.
thats not a capacitor on top of it? none of my split phase GE's have that housing on top of the motor? ill make a vid of my new toys tommorow! i love the motor i got its really neat. and the centifugal switch uses about 20 ballbearings to push a spring out. its neat! and you can easily reverse a replusion motor (so long as it doesnt have fixed position brushes) by moving the brushes 15 deg before or after hard neutral. simple! fantastic design!!!
Well, Im assuming it is split phase, I can see and hear the centrifical switch. I haven't gone into this motor yet. Im also assuming there is a cap under that cover. Have to have a better look at it later.
well capacitor start motors use a centrifugal switch just like split phase. however a permenant split capacitor motor has no starting switch. the capacitor remains in series with one of the windings at all times. your motor is a capacitor start motor. im sure of it!
my great grandpa had a bunch of those! but most were worn out. i got a couple goulds pumps though. my neighbor gave me an mid teens Duro mfg. co. Piston pump. the motor runs excellent. but my pump us issues with the valves and the piston needs new leathers. piston pumps are nice and quiet!!!
soak that plug down with pb blaster, let it set over night then lock the flat end of a pair of vice grips on it then rock it both ways about 1/8inch a few times then turn it out. as for the pump head, soak it in kerosene to soften and eat away at that gunge in it
PB Blaster does work well, that is what I used on the rest of the pump parts. As for that plug, the threads were painted over so what I did put on it did not penetrate. Shouldn't be a problem.

just stick a weed eater motor on it, much lighter and dosent seem like it would need much power.

I have seen a similar pump powered by a small petrol (gasoline) engine.
The engine was mounted BESIDE the pump on a common mounting base.
Generally the petrol engines are a lot bulkier and heavier than an electric motor.

Do you know the seal placement for this pump?
tsmall06 1 year ago
do you by chance know the model number on this, my dad bought one and needs advice as to where the seals go on it. Thanks a bunch

Very interesting old pump!
I have the virtually identical piston pump built here in Australia under the (MacPhersons) "AJAX" brand name. Model "A1 1/2" meaning a 1.5" bore.
Apparently there was an "A1 3/4" which had a 1.75" bore.
There is a much updated style sold under the "Powermac" name.
I am going to restore mine.

Thats right! Wonder why I was thinking it was split phase, guess that would be kind of redundant.

Can anyone tell me the seal placement for the water pump shown above? Thanks a lot, my dad just got one and does not know where the seals go on it.

@tsmall06 Do you mean the rubber rings in the piston or the rubber washers for the one way check valves?

do you have a practical use for it?

that would be kick ass if you can get a low idle engine on there like a briggs
