This series is a typical mechanical seal for process pumps. It is similar to the SL2-series, and can be applied to high viscosity fluids and slurries. Shape and materials of the stationary ring are the same as that of the SL2-series. It is widely used as a standard mechanical seal and our records indicate substantial balanced and unbalanced available, with various material and shape combination suitable for a wide variety of needs.

Application range : Dw: 20...80 mm. Pressure: 12 bar. Temperature range: -20 oC ~+200oC Circumferential speed: 20 m / sec. Item no.
