FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
