Products Name:Model M7N mechanical seal
Products Details:Single end / non balance / arbitrary rotation / DIN24960 standard, M7N series is widely used, interchangeability is strong, sealing ring is not tight embedded, easy to replace. The pushing ring is jammed by the driving belt to prevent the spring from falling off. The static ring can be limited, and the spring stroke is limited to avoid excessive wear of the carbon ring.
