The unit is fitted onto the pump shaft as a built assembly, and no further fitting is required. Cartridge mechanical seals are an attempt to over-come the fitting problems of conventional seals.
We use carbon and SIC as the raw materials for manufacturing the rotary and stationary seal parts. Due to the characteristics of the SIC, the product is endowed with the performance of stable chemical properties, low thermal expansion coefficient and good wear resistance. Besides that, the product is equipped with strong cast iron which gives it long service life. As for the secondary seal, we use EPDM to help the product gain the advantages of weather resistance, ozone resistance, heat resistance, acid and alkali resistance.
We adopt stainless steel as the raw materials to manufacture the frame and face of the seal, which makes the product be of rust protection, high impact resistance, and long service life. With strong technology – computational Fluid Dynamics (CFD), we establish exact geometry and make sure the whole production process conforms to the original production standard of the Alfa Laval. The working principle of this product is to form the thin liquid film between rotating ring and shaft, so that it can efficiently prevent leakage of medium and make the end face lubricated, which help achieve the sealing effect.
