Product Summary

High pressure seals are critical components for rotating equipment under high pressure. A high pressure seal is typically designed to operate within ambient pressure to about 1,500 psi. At a very high pressure, the seal must have sufficient strength to resist extrusion into the clearance gap. The chart below illustrates the recommended limits of the combination of clearance gap (diametral), seal hardness, and pressure differential. A high pressure seal has techniques to avoid extrusion in whicn include decreasing the clearance gap, increasing the elastomer modulus (Mod 100) and the use of backup rings. Backup rings can be made of many rigid polymeric materials and are used on the low-pressure side within the gland to help prevent extrusion. Standard size backup rings are available for a high pressure seal in many materials.High pressure   seals are designed for heavy duty service involving high pressure and sliding velocities. This seal has positive drive arrangement and sturdy construction making the seal suitable for high pressure application. Multiple spring design provides uniform face loading. The seal is supplied as a cartridge unit and can be directly bolted to stuffing box. These seals are normally used in main oil pipelines, water injection pumps and boiler feed water pumps.A mechanical seal is a device which helps join systems or mechanisms together by preventing leakage (e.g., in a plumbing system), containing pressure, or excluding contamination.
