Product Name: Steel spring for mechanical seals
The steel spring energizes the seal and supplies all the load needed for sealing when the media pressure is too low to fully actuate the lips.
The spring also makes up for variations in gland tolerance and normal seal wear. As a seal loading device, a metal spring is more accurate than devices such as O-rings for controlling friction. The flexible spring allows for an extensive tolerance range that can help surmount hardware misalignment and eccentricity, without causing added friction or the inability to seal.bellow spring
