feature

· Sealing Function: The primary function of the rectangular ring is to provide a seal that prevents the leakage of fluids or gases under high pressure. It ensures that the pump operates efficiently by maintaining a tight seal during operation.

· Reducing Friction and Wear: The rectangular ring reduces friction and wear between the plunger and the stuffing box, thereby extending the lifespan of the plunger and other components.

· Maintaining Pressure: It helps maintain internal pressure within the pump, ensuring stable performance under high-pressure conditions.

Position:

· Inside the Stuffing Box: The rectangular ring is typically installed inside the stuffing box, working in conjunction with the packing and the packing gland. It is positioned between the plunger and the stuffing box, providing a seal by compressing the packing.
