JM7N

JM7N系列应用广泛，互换性好。密封环非紧嵌入，替换方便，推环由转动搭子卡住，防止弹簧脱落。静环可限位，弹簧行程 受限制，避免碳环过度磨损。

The JM7N mechanical seal range is designed for universal application and ideal suited for standardization. The loosely inserted seal faces are easily exchanged, permitting all combinations of materials and stock rationalisation.
