40CY-50 sewage pump spare mechanical seals

Single face/non-equilibrium/arbitrary rotation/in accordance with DIN24960
H74N series are widely used with strong interchangeability. The sealing ring is not tightly embedded and easy to replace.The push ring is stuck by the transmission strap to prevent the spring from falling off.Static ring can be limited, the spring travel is limited, to avoid excessive wear of carbon ring.
