Magnetic mixing tank has characteristics of no leakage, fully sealed, corrosion resistance and energy saving. Because of its non-contact transmission torque, taking static seal to replace dynamic seal, it solves the leakage problem that other shaft seals cannot overcome. Since all materials and the mixing components operate in a sterile and sanitary state, the magnetic mixing tank is an ideal replacement for processing machines in the industries of pharmaceutical, fine chemicals, cosmetics and bioengineering. It is a sterile liquid mixing tank with mixing device installed at the bottom or sideways if necessary, enabling CIP and SIP. There can be different seal heads, jackets or single wall, from which customers can choose for different combinations according to requirements.
