The Piston Pump Orifice is a sealing insert positioned on the piston pump head in conjunction with the mounting screw. This provides a tight seal around the piston assembly, preventing internal fluid leakage and maintaining pressure integrity. It ensures consistent contact with adjacent parts, reducing wear and enhancing the pump operation. Attributes:• Supports stable pump operation under load.• Provides tight contact for minimal fluid loss.• Prevents internal fluid leakage around the piston.Applications: The Piston Pump Orifice is used in piston pumps to seal the pump head assembly at the piston and screw interface, preventing fluid leaks and maintaining consistent hydraulic pressure for efficient pump function.
