Hydraulic unit for automatic pusher

[Lakhdar]

Good morning all ! I hope to be in the right place I have just recovered a small hydraulic group, which I will use to transform a manual pusher into a car, but I do not know if the order allows it. I therefore ask for your help.

[Rabbit]

A pusher of what?

[dedeleco]

The maximum pressure Pmax 700 bar is enormous, gigantic, equivalent to 7km of water above, that at the bottom of the oceans of 7 km deep, and therefore there is an error on this label ????
If they are mbar, it is low with only 0, 7bar or 7m of mas water ???

So everything is incomprehensible for this pump motor !!!

Please give as much info as possible, history of past uses, various photos, etc.

It is a hydraulic pump with high pressure and very low flow

The indicated flow x pressure gives a power of 480 W

With that, you can raise mountains, but very slowly.

So, a special material of high pressure fittings and hoses must be used, for example for hydraulics.

oh yes, you need steel pipes and well screwed fittings ...

700 Bar, it's not nothing, it's the equivalent of 700 kg on 1 cm²

I wonder if it's not a HAWK pump

Impossible to know without the photos of the inside of the box !!!

In the labs, we go up to much more 10 to 15Kbars with this kind of material, for high pressure bomb !!

With diamond cells, we go up to the megabar to find out the properties of materials towards the center of the earth.

hello, to be more precise, I have a horizontal sausage pusher, and I was thinking of putting a small jack at the end of this hydraulic unit, which was used to crimp fittings.

Well I see that it takes a regular in hydraulics!

This pump is twice the pressure usually used in hydraulics but is not a rarity for its application which allows to lighten the clamping tool allowing a smaller cylinder with a shorter stroke and an equivalent outlet pressure.

Yes lakdar it is possible to use this 250 watt pump to operate a cylinder!

You can give me your real application with the useful outlet pressure that you need and I will calculate the cylinder diameter that you must obtain from a hydraulic cylinder manufacturer.

Also give me the capacity of the oil tank to calculate the length of the cylinder that it is possible to have.


You can also bring the device to a hydraulic dealer
which will do the math in no time and provide you with the right cylinder for your application.


Hi Rémundo!

The Hawk piston pumps that I know well are intended for water and in particular for pressure washing.

So everything is incomprehensible for this pump motor !!!

Well, it's hydraulics!


Dédélecon has still got its nose in an area that it does not know but hey we are used to it!

PS: When you don't understand you don't put your nose in it !!!

classic excavator hydraulics are 200bar, but hydraulic equipment at 700bar is not that rare

enerpac cylinders is 700bar, with flexible and automatic connections that go well

small bottle jacks often also work much more than 200bar
