introduction

Single end/balanced/arbitrary rotation/spring isolated from medium/in accordance with DN2490 standard

HJ92N series mechanical seals are suitable for solid particles and high viscosity media, such as sugar and paper making, sewage and other industries. The spring is protected from sticking and damping in the medium, which makes the design stable, safe and reliable.

Operating limits of running parameters

d,=18..  100mm 0.625 ".4"

P,)=0.2... 25bar  3... 360PSI

ZF92N: t=-50... 220℃ -58°F... 430 ° F

V,=20m/s  66ft/s

ZF977GN: t=-20.... 180℃ -4°F... 356 ° F
