Default Mascon double action piston pump

Hello all
I was looking in the scrap yard out home the other day for some batteries and found a Mascon double action piston pump and, long story short, it came home with me.
when I got it home I could not believe there was no wear on the guide rods or piston rod, it wasn't seized and the pipes unscrewed. Even the greasers are there.
I took the valve caps off, tipped the flaky rust out and everything looks good. As per usual I didn't have time to have a look into the guts to see how the bore is but I reckon it'll be OK. Sadly it's been converted to a V belt (it was broken) so flat belt pullies are gone.
Now I'm back in Brisbane I've been trying to look into the Mascon pump history and found there isn't much information available out there. About all I could get was they were made and sold by McPhersons. Is this correct? I thought it is but better to ask then to assume wrong information. McPhersons also sold Ajax didn't they?
The pump I found under the heavy steel pile is a 2E which I assume is a 2 inch bore and I reckon it's about a 4 inch stroke. The outlet is about 1 1/2 if my memory serves me well. It was all a bit of a hurry. Finding it in the heavy steel pile was kinda appropriate. It weighs 96kgs.
Nearly all the Macson pumps I found on the net were huge. 5x5 and the like. By looking at the ad it seems that they made 5 sizes.
I did find a couple of ads and one ad was for 1936 and McPhersons did not advertise Ajax pumps but the ad had pumps which I've seen as Ajax pumps.
So did McPhersons make Macson pumps and later renamed them Ajax or what's the story?
Cheers and thanks
Scott
PS: didn't find any good batteries if your wondering.

This ad from The Mail in late 1936

Hi

I recently acquired a 1 1/2 inch double action piston pump, very simular to the Ajax A 1.5 but with very minor differences. The only marking in M cast into the top of the pressure chamber and the letter M punched into the type space on the tag on the gear housing. Is this pump a Macson Pump? This is the only pump of this type I have seen. I will take photos tomorrow and put them up. Also I am guessing that the name Macson comes from the manufacturers name McPherson's. Any thoughts?

Regards

Ian

Hi Team,
Macson pumps, machine tools as well as Ajax certainly seem to have been brands used by McPherson's over the years.
My 1955 and the 1960 Centenary Catalogues mention both Macson in the machine tool range and Ajax for water pumps at those times.
TROVE may bring up some info.
Link mentions some possible sites of interest for further study.

Interesting subject this of another now gone great Australian Company with manufacturing resources--all no doubt gone to China.

Cheers,
Eddie B.

This one is a Macson.
I don't have a tidy knowledge of the history of the brand name.
As far as I have scratched around and learned over the years McPherson was importing and selling workshop machinery,rebadging them with his name, before making his own copies of some machines.I will go out on the limb a little and say that the company was importing as 'McPherson' and then progressing to making copies of lathes and workshop machines.The next phase might be McPherson and Son,and their own product during that later time was branded Macson.My old flat bed lathe is from somewhere close to 1915,and is carrying a large cast embossed 'McPherson' logo.
The 'MACSON' brand as far as I know is the joining of MAC(McPherson),and SON.Someone who 'really' knows might correct me?
My fathers old lathe is definitely one of those two or three name maker pommy lathes,imported,then badged with a 'McPherson's' agency badge.

Yes well these little pumps were oft used to supply domestic water . Operating with a pressure switch and an electric motor mounted on top . Uncle Herb had one in his later years at the old farm . I now have that pump but have not done any thing with it.. It was described in the early Mc Phersons cataloque as the Ajax self oiling piston pump type A1 1/2.

Hello all
Not many do Paul. I haven't really forgotten about the Macson/Ajax which came first, the chicken or the egg saga and have been doing some research.
Mr Goose's early McPherson's catalogue with Ajax pumps in it may give some light. What year is the catalogue Mr Goose? A scan would be great!!!!

Hopefully my new camera will be here today to take some pictures of the pump in question. If you put Paul's pump on some dirt and take the drive pulleys off, you'll see ours.

I've always wondered if old Billy used the Ajax name for pumps to capitalise on the Ajax name as in the fastener range? Ajax were the rivets used on the Sydney Harbour Bridge I found a reference to somewhere?

Cheers Scott

Hello
Woohoo....camera came.
Those with keen eyes will notice a couple of teeny weeny differences between Paul's pump and this one.

Cheers Scott

Hello all
It's not as rusty as Paul's Cobba. Ours has some paint on it.

OK now. Some things I've found out. If any item is wrong please tell us about it. Mr Goose, your cattledog may be very handy here seeing it's an early issue.

- Macson trademarks from around 1922
- Ajax pump works existed from around 1939 to 1966
- Ajax pump works opens in Kyneton 1948
- Ajax acquires Forrers in 1988
- KSB AG acquires Ajax and becomes KSB Ajax Pumps in 1991
- Ajax diamond label trademark (bolts and stuff I think) from 1929-1972 (hence the Sydney Harbour Bridge link)
- 1st Macson lathe about 1915
- Macson machine tools closing down 1981-1982

So from that you could kinda surmise that Macson pumps were built up until about 1939. When did they start? 1922 or a bit before? Anything wrong with that theory?

One way our pump can be very roughly dated is by the use of Gargoyle grease. When did Gargoyle grease become Mobilgrease? Around 1930?

Cheers Scott

Slightly off topic; ubtil a few months ago I servicedthe lift at the former McPherson's building at 76 Commercial Road, Newstead. Lift is original from the mid 50's excepting the buttons.

In the building entrance there is a brass image of a micrometer in the terrazzo.

Sorry for calling it "rust" Scotty, I meant "Patina".

Hi All

To get back to my question, is my pump a MACSON?

Regards

Ian

PS: Hi Scotty I have a friend with a Macson just like yours.

Hey guys I am currently trying to restore a macson style B double action piston pump. I’ve got most of it pulled apart but I’ve come to a holt trying to pull the plate that stops the plunger and plunger Rod from coming out..... (the plate has four bolts in each corner, a large hole in the middle for packing and two threaded holes either side) the plate wiggles a bit but doesn’t want to come out (believe me I’ve tried) is there a trick to pulling it off?

PLEASE HELP

Scotty will be able to set you right Jaybear.
I have a vague memory of mine coming apart there.I think the little brass tab has some instructions.From memory once the square cap is loose you turn it?I'm only guessing now,trying to remember,but i think the brass pump tube keys onto a couple of lugs when turned?

Yes well we must clarify which pump we are discussing The pump that Paul shows is no doubt a Macson , very much the same as the Billabong ,again an Ajax. The pump that Clappers hows is the Ajax pump mentioned previously that is used for domestic water supply ,pressure switch and top mounted elect motor.

Yeah, right. I have no idea to tell you the truth.
I suppose it' a good enough excuse to see how it goes apart. Been needing an excuse to do it. Now there's one. Goodo.
Give me a few days Mr Bear.
At a guess: that square plate is how the liner comes out. There may be 2 tags on the other side of the plate which has a screw or two attaching it to the liner so when the plate comes out, so does the liner.
Sound feasible?

Cheers Scott

Hello all
Good memory it seems. It looks as the liner should come straight out and the turning needs to be done to withdraw the stuff box without the liner

Cheers Scott
