An Internal Retaining holds different parts in place by fitting into a groove inside the pump housing. This ring prevents the axial movement of components, ensuring they remain securely in their designated positions during operation. The ring withstands high pressures and stresses to maintain the integrity and functionality of the piston pump.Attributes:• Maintains accurate spring tension for consistent performance.• High load capacity to support spring forces within the pump.• Provides enhanced retention to prevent spring displacement.Applications: An Internal Retaining Ring is located inside the piston pump barrel, where it secures the spring to maintain the correct tension and alignment of the spring, ensuring the proper functioning of the hydraulic system.
