ok, this is definitely stuff for engineers and not for chemists (like me) :-) Thanks for the input. If I don't find a good engineering company that can give me some direct answers based on the same information that I posted here, I will come back to you ;-) For the hydraulic pressure: I don't...

wow, a lot of things that I never heard of before :-) I have not yet decided which engineering company could develop this 'monster pump', but this could be very useful information. Thanks. However, someone told me a stepper motor with torque of 20Nm and bal screw of 5 x 20 would give me...

The direction will be vertical and I will have to overcome a pressure of 1400 bar (max.) that is put on a plunger of 10mm. Basically, it will be a syringe pump, driven by a stepper motor for high pressures. This will be used in analysing equipmant for laboratories (HPLC)

well, 1200 kg linear force would give about 12000 N Since I will be pushing only in 1 direction, I think a linear hybrid would be the thing to have ? But I can see that even the biggest one can only push 500 lbs (200 kg) ...

stepper motor for 1200 kg linear "force" Hi all, For a project I need to bring over a linear force of 1200 kg onto a steel rod of about 10 mm. I would like to have some guidance in how I could do this with a stepper motor. How 'heavy' does this motor have to be ? I most powerful ones I've...

yep, I just figured it out myself. I was confused with the term 'ton', which sounded as 'really really a lot', but is actually just 1000 kg ... :-)

What all respect, but I don't think this is right...

Pressure would be atmospheric, because the pressure is building up the moment the syringe starts flowing. The syringe has to be able to flow so fast that the whole system reaches a backpressure of 20,000 psi. I don't know if you are familiar with HPLC, but this is exactly what I am planning to...

Hi all, I am looking for the correct calculation of the torque (or linear force) that is needed on a syringe plunger to overcome a backpressure at the nozzle of 20,000 psi. I have to decide which syringe pump I will be using for my application, but their is a lot of choice and mainly I need...
