This series of vane pumps features excellent flow-versus-speed characteristics. An internal flow control valve ensures that the pump’s output flow remains constant or decreases as rotational speed increases. An integrated safety valve prevents hydraulic system overload, with adjustable pressure settings. These pumps are widely used in power steering systems of medium- and heavy-duty trucks, as well as in power steering systems of other construction machinery.
