SS / SSN & DP / DPN Features and Benefits Two standard gland configurations For sizes from.000 to 3.500 (24-85mm) the seal is a SSN or DPN. The SS / DP are available from 3.625 to 4.750 (90-20mm).

3 SS / SSN & DP / DPN Features and Benefits Two standard gland configurations For sizes from.000 to (24-85mm) the seal is a SSN or DPN. The SS / DP are available from to (90-20mm). /4 NPT flush / vent port supplied with a stainless steel blanking plug as standard. Fits both small and ANS+ box bore pumps without modification. Modular Seal Face Design Hydraulically balanced face design ensures optimum fluid film during process fluctuations. A wide range of inventoried materials allows maximum flexibility and delivery performance. Metal-to-metal pin drive eliminates potential impact damage. aptured Rotary O Ring aptured O ring design prevents extrusion under vacuum conditions. Multi-Spring Design Alloy 276 helical coil springs ensure accurate uniform seal face loading throughout the seal life. Springs are placed out of the product media to eliminate clogging and loss of face loading. Reliable Drive Drive screws clamp directly on to shaft or sleeve to minimise drive loss. Drive screws which do not deform the seal sleeve ensure easy removal and refitting for equipment maintenance. Robust setting clips guarantee correct working length and can be re-used for removal and refitting. SSN artridge Single Mechanical Seal DPN artridge Double Mechanical Seal
