The BIERI Radial Piston Pump HRK is a lightweight, compact high pressure pump with a hollow shaft design. This allows a very space-saving connection of the motor without the need for a housing and coupling on the box cover. With optional pump protection valves, the series is unmatched in terms of versatility and spatial optimization.
