Mechanical seal is the most advanced and effective obturator for rotating pump shafts. Mechanical seals are designed to prevent leakage of the rotating liquids, serious accidents are excluded.
General transition from packing to the rugged mechanical seals in the construction design of the centrifugal pumps renders possible to improve pump efficiency and thrust control valves usage can ensure minimal axial rotor’s take-of run. Qualitative mechanical seal gives noticeable reduction of the power consumption level of the pumping facilities and systems.
