the opposing pressure starts to exceed the kinematic pressure. Centrifugal pumps are sometimes used in hydraulics as supply pumps .

Pressure that is produced after filling, e.g. on the gas side of a hydraulic accumulator or on pumps on which the suction side is pressurised.

All measures which a manufacturer of hydraulic pumps can take to keep the amount of noise generated as low as possible. Alternative: secondary noise reduction measures

above an inlet or outlet opening. In the case of a negative inlet height, the suction pressure for pumps is lower than the ambient pressure (Figure Z 8).

spindle pumps are very quiet. However, no volume adjustment is possible. The pressure range is largely under 60 bar at an output volume of up to a few thousand lpm. However, screw spindle pumps for up to

Velocity at which the pressure in a device increases. It is measured in bar/s and defines, e.g. on pumps, the amplitude of the pressure pulsation-induced oscillations and with it also the amount of noise
