JH7N

JM7N系列应用广泛，互换性好。静环采用浮动式，安装方便，推环由转动搭子卡住，防止弹簧脱落。

其它特殊的技术处理包括静环可限位及弹簧行程受限制，避免碳环过度磨损。

The JM7N mechanical seal range is designed for universal

application and the

interchangeable parts concept is ideal for

stock rationalization. The seal faces are

loosely inserted and can be easily

exchanged, the thrust ring is

retained by the drive lugs

perventing the spring falling out

. permitting all

combinations of materials and

stock rationalisation.
