I look for gear manufacturer for hydraulic pumps

as from title I look for a gear manufacturer for hydraulic pumps, if possible it should be a manufacturer of hydraulic pumps.
the working pressures are low type on the 30 bars and the standard hydraulic pumps are too large and not adaptable to our project.
all in a circumference of 60 mm maximum.

Thank you.

I'm sorry, but I don't know if you're looking for a supplier or model 3d.

What kind of gear? internal or external gear pumps?

 

[Mauri:66]

is it a rebus?

 

[MFT]

from what I understand you would like to build....the pump

Are you crazy? ! (in the positive sense)
However, I suggest you insert the compensated bushings, you are still "remained" to the old type of construction:biggrin:

p.s: I worked a few years for a well-known gear pump manufacturer

p.s.2 and also (ot): check the private mail. Thank you.

I stayed at the old model because some years ago I found myself in my hand a gear pump for the lubrication of the old lathes that we used in high school and then I put myself to make some account and I modeled one. In fact there is the optimized version that has so many extra things, including the self-lubrication of the bearings and is made by round and not by painting, only that I do not have the charts of the courses since for those data is equal to this which is complete in its analysis.

I need to know you, I want to see who you are and what you do.
You are one of the few (there are others who are not offended) who in here seems like a real engineer, category to me very dear:smile:.
I wanted to do that in life and to listen to family members I made the greatest caxxata of life.
I ended up being a designer, but I always miss a piece.
There is little to do, the designer is true that you do on the field but, must have a scientific culture and this does not learn it in the workshop.
I would like some time to get back to studying but not for the title of study, for the taste of giving more rigor, order and consistency to the things that are learned superficially in life.
I wonder if life will give me this opportunity.

Well, this is the result of many late nights until 2 and a half in the morning after studying for university exams... and the many mornings from 2 to 5 of the summers.
When I have time I close in my world and open myself to the study of new things, which I still ignore in various fields. over time I'm building some charts that allow me to make measurements very quickly and the checks differ by a 5% and most because "I want" to read the interpolation on the curves.
In my archives there is always some material useful to the survival of the profession:finger:

I mainly personally take care of r&d design of machine tools, carpentry, various cinematisms, small and large mainly mechanical or hydraulic or aeraulic equipment, delight me in thermal treatments and processing, safety at work and design and construction according to legislation, organization and optimization of related activities. this and other in the various years for work or for needs or for pleasure, combined with the possibility to work in the workshop and be productive: from the lathe to the milling machine, from the file to the magnetic drill, to mount and test plants, weld, fold sheets etc etc etc. etc. I like things and I can't forget them.

I broke my back and my brain between books and work.
I took an old degree, but not in engineering.
I did it while I was working and started working in the yards.
but I was wrong to listen to relatives' advice, I should have studied what I liked and not what they recommended.
It will be for another life, this has gone like this:

What the fuck?
And I have to tell you that you must never have regrets?
try to see the half-full side:
Even though you don't have a degree in engineering (but I still think you have technique) you know how to pack.

If I could trade my degree with the knowledge that's in here, I'd do it flying.what matters, especially in this field, is not the form but the substance!and you have a lot of them:

Thank you for your estimate.
I come from science with a degree in economics.
that little I learned I owe it to the hard head and the luck of having met really remarkable people (unfortunately there are no more).
I'm not living a great time, you look around and you see the desert, companies that close, the country that rolls... I don't know what to think.
I feel like closing the hut and leaving.

Sorry I was in a hurry to post.
I really want to build a gear pump
flow and pressure are low.
the pump will have to stay all inside a 98mm cylinder with a 500w engine of the same size.

I am now using a lobe pump and since I have problems with cold operation I would like to switch to a gear pump to solve some problems.

info on pumps
we installed a lobe pump with mineral oil iso 32
to improve the pump at low temperatures we used a bio iso22 oil with high index of visciosity.
so doing we have improved both at low temperatures and at high temperatures,
to use this oil we had to increase the precision of the pump
the latter has problems of smoothness (because too precise) and with dirty oil (small debris) the pump tends to get stuck.
the control unit that I am building is very economical, there is no space, there are no euri and no one will ever replace or clean oil filters

At this point as many automatic gates I would like to try an internal gear pump.

the streets are two:
-a-find a manufacturer of very cheap and small internal gear pumps
-b-or find gears for pumps and build the pump carcass to be inserted into the control unit.

then the questions are 2:
road -a- do you know manufacturers of internal gear pumps?
road -b- do you know gear manufacturers for pumps?

like all things if there are companies that build pumps of this size are happier than investing money to build it.

Additional notes:
I have in the house an old pump with gears z13 d17,5 h20,5 module a middle way between 1,125 and 1,250.
I adapted this pump with my control unit and noticed that:
with piston loaded with equal weight, that this gearbox and my last more precise lobes control unit have about the same speed.

So I thought about self-constructing her by taking gears and self-constructing my pump carcass... say what's wrong? ? ?

thank you very much and cordial greetings

Excuse me, but what pressure are you going to?
What's the scope?

for 98mm cylinder do you mean diameter 98 mm?

If you have high pressures, let the idea of self-construct you because you should realize enough "series".

in all cases to me it turns out that there are small pumps (for external gears) for control units (they would be in a diameter of 100mm quite well). go see any builder and you will see that you find all the sizes you want.

pressure 10 30 bar piston diameter 40mm internal boring

I don't have high pressures and I can't spend on a finished pump that I have to disassemble throw away the pieces rebuild parts and adapt it to me. I'd just throw away money.

I'll be the one, but I'll be the one who doesn't understand.

from how you wrote it looks like you want to put a pump in a cylinder :biggrin:

Let's do something simple: If you can, take a picture of your system so we can figure out a little better.
among other things I am also convinced that you are confusing the external gear pumps with the internal ones.:tongue:

to answer your question: make ad hoc a pair of gears to fit your needs will cost you at least as much as a new pump. If we talk about micro pumps (pompe group 0.5...the family of pumps dedicated to the control units) you can well take it with max 50€.

maybe here you could find something that does to your case:
http://www.vivoil.com/it/indice-prodotti/pompe-unidirezionali/
http://www.vivoil.com/files/vivoil_p_it.pdfother pump manufacturers are:
house, salami, sauer danfoss, Marzocchi, hp (group bondioli&pavesi), oleodynamic petrone, meta, etc.

edit: ....forget "only" the world leader: bosch

thanks for your many answers

I can't put you photos:
These are external gear pumps but adapted to work immersed in the oil all together with the engine.

to cut short I decided to proceed with the construction of the pump, you know some company that produces gears beyond meves, microengines, moreali....thanks you

 

[meccanicamg]

you can build a multi-stage pump or increase the flow or pressure depending on how you connect the travases or if you want larger flow rates and you have a low gear module increase the b band of the same.

I think the matter is easier than what you think without having to shake up internal gears. all gear builders you find on white pages like ceba and others.

 

[Ing Italy]

multistage pumps i.e. centrifugal multistage? .I had never heard of volumetric multi-stage masses if not sometimes those in palettes also because the volumetrics already give high prevalences. ..mixed multistage are monsters then
