We are using Moog RKP 80 cc pumps (radial piston pump) in our press machines. The maximum tonnage of this machine is 1150 Tons at 300 kg/cm2. The image showing the installation of the pump is attached...
Thank you very much everybody for you valuable help. I have rejected the material and am going for forged En 24 shaft. Even I thought that the high carbon content will make the material brittle.
Thanks once again..
We make hydraulic press machines. We are making a cylinder having a diameter of 1100 mm. The piston size is 800 mm. Length of stroke is 150 mm. The maximum pressure we want to exert is 300 kg/cm2. The chemical composition of the steel which we getting is:
C: .75% Cr: 1.3% Ni: .32% Mo: .18%...

Oops I forgot to mention.. tbuelna ... The images of the valves are that of the inlet valve seat surface before we rework it.
Valuable suggestions awaited....
Thanks once again for the replies. I agree with your point Adrian. We were thinking of increasing the tension of the spring to keep the valve closed even while pump is idling. Regarding the stem of the valve, I am attaching some images of the valve and the pump...
Thanks for the reply. We use this pump on a hydraulic press. The pumps goes up to 230 bars maximum pressure. The pressure is intermittent and is retained over a check valve.
Yes .. the suction piping comes from a tank/reservoir at atmospheric pressure, and that the 70 bar measurement is the...
We are using as radial piston pump which is having seven pistons. The pump rotates at 1440 RPM and delivers 24 litres of oil per minute. The pump is a closed type pump and sucks oil from a high level tank. We have connected a 1 - 1/4" hose to the suction line of the pump. The through and through...
Once again .. Thanks a lot for he replies. Sorry for such a late reply - just joined work again -- was hospitalised..
Well Adrian.. you are correct. I agree with your explanation. You said "It's an elegant solution, it works and the pump name plate is correct. You'll agree once you understand...
Thanks for the replies friends. But the concept is still not clear to me. The pumps name plate says DRS. That means it is a flow control model with X to T line plugged. Now as Adrian says, the manufacturer has adapted the control to work like a power control. This is what I am not quite clear...
I am maintaining a hydraulic press which is having a piston of 600 mm. It works up to 280 bars and creates a maximum force of 800 Tons. It is having a Rexroth A10VSO 71 DRS/32 pump which delivers 100 lpm of oil at 1440 rpm. It is coupled with a 35 HP electric motor. Please find attached images...
