Apex Sealing did a recent mechanical seal repair of our S1 Big Bore 1.750", Silicon Carbide vs Silicon Carbide, Aflas 316SS.
As received Repaired to like new condition
Mode of Failure:
When product dries, it leaves a powder on the seal faces. The faces were stuck together during pump startup. When the pump started up, the impact of the anti-rotation pins caused the Silicon Carbide faces to break.
Repair Process:
During the repair, we used a complete mechanical seal repair kit in this seal. We added new; Tungsten Carbide Rotary face, Tungsten Carbide Stationary face, Aflas O-rings, springs, setting clips, set screws, Teflon back-up rings and Teflon gland gasket. We informed the customer to use a flush to keep the seal faces clean and switched them to Tungsten Carbide faces.
