Function and application

    •  Double-acting liquid lubricated mechanical seal

    •  Two identical pairs of seal rings

•  Ideal mechanical seal for applications for medium pressure range up to 40 bar (abs.)

•  Use of modular design opens up many different extension options

    •  Mechanical seal used most in agitators worldwide

Advantages

•  Life cycle cost savings due to extremely robust construction

•  Use of FEA ensures optimized stress distribution in every seal ring

•  Special spring designs ensure uniform pre-tensioned conditions even at significant agitator shaft displacements

    •  Almost zero-leakage under the roughest conditions

    •  High tightness/ low leakage
