A Backup Ring is a sealing part used in Gear Pumps to prevent leakage between the Gear pump housing and the rotating Gear shaft. It is typically made of plastic material, that can withstand the pressures and temperatures encountered in Gear pump operation.

Attributes:
• Helps maintain the desired pressure levels within the Pump
• Withstands the sliding motion and compression forces exerted by the rotating Gear shaft

Applications:
A Backup Ring acts as a barrier, preventing the hydraulic fluid or lubricant from bypassing the seal and leaking into the pump housing.
