The Main Hydraulic Pump Head is a key structural and hydraulic distribution component in an axial piston pump system. It forms one end of the pump casing connection side and provides the interface for hydraulic ports, internal flow channels, and mounting for core internal elements such as the valve plate, cylinder block, and bearing supports. This component is manufactured to high precision to ensure tight tolerances between the rotating group and the fluid flow paths. Inside the pump head, hydraulic oil is directed into the pressure and return sides of the pump through well-defined galleries. It also houses sealing interfaces to prevent leakage between high- and low-pressure zones.Attributes:• High resistance to pressure, heat, and vibration.• Maintains fluid flow direction, pressure balance, and sealing integrity.Applications: The Main Hydraulic Pump Head is installed on the main hydraulic pump to support and align core internal pump components while directing hydraulic oil between pressure and return circuits within the main pump.
