Pump components comprise a body, a drive rotor, housing the vanes, a stator (mobile ciruclar ring) for varying eccentricity and consequently displacement, and side distribution plates with AXIAL HYDROSTATIC COMPENSATION which delimit the inlet and outlet chambers.  A guide block balancing adjustment screw (not to be tampered with by the user), a displacement adjustment piston, a maximum volume adjustment screw, a pressure regulating device, and a pressure regulator adjustment.  Please see Pdf catalogues for further information.
