internal gear pump fixed displaced for around 4.0 e-4 m3/rev.
(OP)
Trying to configure a internal gear pump fixed displaced for around 4.0 e-4 m3/rev.
Cant find any suitable pumps on Parker or BoschRexroth. Can anyone suggest something

Check for laboratory equipment like www.michael-smith-engineers.co.uk

I have a practical question, to work with a double acting piston cylinder (1m Stroke length).
If i want to have a cylinder velocity of 0.5m/s,
1.Is having a pump displacement of 1.5e-4 m3/rev feasible ?
2. and a PRV operating at Pmax= 3e+007 Pa?
3. the pressure that develops in the hoses goes around 5e+7Pa ?
Are these good values????
I want to adjust these 1,2, 3 values to depict a real system. The problem is if i try to make the hose pressure to be around 3 e7 pa then I have to operate prv at 1e7 pa and then the pump displacement goes really high. (4e-4 m3/rev to achieve 0.5 m/s ) and I cant design the hoses drops as no equation is available. Peter here suggests to use some equation for calculating pressure drops but i cant find any relevant scientific papers on it. Please suggest ....
Regards,
Sara.

If 3 e7 Pa means 300 bar (4350 psi) - that is high but probably not too high. What I do not understand is your whole hydraulic configuration. You have a pump at fixed speed which is not VFD controlled, right? The set pressure of the PRV cannot be less than the pressure you see in the hose between pump and cylinder. Otherwise nothing will move.
