Thanks for your information i got a problem that the charge pressure drops from 30 bar to 10bar when the control lever is operated. also this happens when temperature raises to 40°C . That 90series 055 pump is installed on Volvo DD80 Tendum vibratory road Roller
i have a 90 series sauer danfoss. the charge pressure is okay, but the pump makes a knocking sound as if it was losing pressure somewhere inside the pump. I am stuck with this situation.........the pump seems to be producing pressure, but then as soon as I try to move it forward or reverse, it starts making the knocking sound.also the power it is giving to the wheels is very low.............it appears as if the forward and reverse pressure settings are set at too low.I did swap the multifunction valves with a running machine........and that settings should be okay as the same valves work perfectly fine on the other machine.I would highly appreciate your advice.....thankyou

Dont forget true delta charge pressure....is plus or minus case drain ....
