Features

The mechanical seal of this type is one-coil spring seal providing excellent resistance against corrosion and slurry. It is a seal which adopts the clutch mechanism for transmission of seal rotating torque, to make up for the disadvantage of spring drive. The knife edge seal of similar construction is also available to the high-viscosity liquid. (Type: PEL, PFL Pressure : 0.5 MPa)
