AMT 3150-300-92 Viton / Silicon Carbide Seal Rebuild Kit
The AMT 3150-300-92 is the genuine all-seal rebuild kit built around Viton elastomers and silicon carbide seal faces, listed for AMT’s 315, 424, 425 and 426 series pumps. "All seal" is the useful part of that description: this is not just a mechanical seal, it is the complete set of sealing components the pump needs for a proper rebuild.
The silicon carbide specification is what sets this kit apart from the standard build. Silicon carbide is harder than the sand and mineral grit that gets between seal faces, and it conducts heat several times better than ceramic, so the rubbing interface stays cooler and survives moments of marginal lubrication that would craze a softer face. In abrasive or continuous-duty service, a silicon carbide pair simply outlasts carbon by a wide margin.
The Viton elastomers cover the other half of the problem. It is usually the elastomers, not the faces, that end a seal’s life — a secondary seal that has swollen or hardened stops the rotating face tracking the shaft, and the seal weeps even though the faces look perfect. Viton resists the solvents, acids, oils and heat that destroy nitrile. Fit the kit complete and confirm the part number against the parts breakdown for your pump before ordering.
