An Internal Retaining Ring, also known as a snap ring is a type of fastening device used in a piston pump to secure various components in place. It is designed to fit into a groove or recess on the inner diameter of a cylindrical bore or shaft, holding the components securely. It consists of a thin, flat, circular metal ring with a small gap or opening. This opening allows the ring to be expanded or contracted for installation or removal. It ensures the piston remains properly aligned and centered within the cylinder, maintaining efficient and effective pumping action.Attributes:• Provide strength and durability.• Designed to resist corrosion.• Withstand vibrations and rotational forces.Applications: An Internal Retaining Ring helps to maintain proper alignment and ensures the efficient operation of the pump.
