Please state the required setting in clear text on the order
(e.g. qVmax = 20 l/min; pzero stroke = 70 bar).
The pump will then be set to the desired values and the operating noise optimised accordingly.

Without indication in clear text, the flow and the zero stroke
pressure will be set to the relevant maximum values and
the operating noise optimised to these maximum values.
Thanks to their specific design, type PV7... vane pumps with adjustable
displacement boast a low flow pulsation and achieve very high
repetition accuracy with low pressure peaks during the down control.
The noise optimization achieved by adjusting the height
adjustment screw provides for a low operating noise.
Hydrodynamically lubricated plain bearings ensure a long life cycle.
The axial compensation of the displacer provides optimum volumetric efficiency.
Variable displacement
