Hyd Pump - What did I just buy?

[Lil Giants]

So the magnetic connection will determine how much pressure it's capable of?

I'm not sure Joe I've talked about these with Freddy awhile back , we both agreed It just will not work for what we need . I guess in a sense it will these pumps are for some labatory/medical use not requiring a lot of press I think The 2 small pumps I have came with the motor and mag drive , not changing anything on them I can't get but a drip out of the outlet . for the kind of Pressure Joe and I get out of the bigger 1's they must have 1 heck of a magnet coupling . I didn't pay alot for the few I have ,but they require modification for our use . for what the cost new , your better of buying what we have available in the hobby already . I'll use what I have , cause I have them now , but in the future will just save for the Jung set up . I was really impressed with it for the few min. I took the controls of Ed's excavator . next is valves I just keep going back and forth on buying or make . I got to speend another grand on a collet chuck and collets for the lathe so I can make the plungers being that the big chucks I have now can't hold much smaller then 3/8" . tooling seems to win out these days though .

well i finally got 1 to a useable state

smaller original pump as I got them



The 1st thing I did was cut the back of the housing down where ththe motor couples to the pump to give me more useable shaft without a slotin it for the goofy mag coupling . then made the sealing/coupling plate much like Joe did . then , using the bell that came with the motor to attach the motor much like the original . Instead of mag coupling I got the smallest bore lovejoy coupling from McM . The motor that came with it musta been gelded so , I had a 55T integy lathe motor and a RC4wth 4:1 reduction put it all together and ahlala insta pump at 15 bar pushing against the gage . bear in mind this is the smaller of the 2 type I have . it also has no relief valve .
