feature

· Sealing Function: The compression ring applies pressure to the packing or seals, ensuring they tightly fit between the plunger and the pump body, preventing fluid leakage. This is essential for maintaining the pump's performance under high-pressure conditions.

· Fixing the Packing: It holds the packing in place within the stuffing box, preventing it from shifting during the plunger's reciprocating motion. By applying consistent pressure, the compression ring helps the packing effectively fill the gap between the plunger and the pump body, creating a reliable seal.

· Reducing Wear: By compressing the packing, the compression ring reduces wear on both the packing and the plunger during reciprocating motion, thereby extending the lifespan of the packing. It also helps distribute pressure and heat evenly, avoiding localized wear and overheating.

Position

· Inside the Stuffing Box: The compression ring is installed inside the stuffing box, positioned directly above or below the packing. It is located between the packing and the packing gland.

· Sealing Assembly: In some designs, the compression ring is part of an overall sealing assembly that includes multiple packing rings, spacer rings, and other sealing components.
