Product Overview
Custom Bottom-Drive Magnetic Stirrers to Meet Your Requirements
Whether you need specific motor power for different viscosities, a tank sized to fit your production space, or a custom impeller shape to optimize mixing, our bottom-drive magnetic stirrers can be made to order.
From small-scale experiments to industrial production, low-power precision stirring to high-power mixing, standard tanks to custom dimensions, and general-purpose impellers to structures designed for special materials, every detail can be tailored to your application for more precise and efficient mixing.
Product design
The containment shell and tank use a detachable design for easy maintenance. The tank connection flange is welded. The containment shell and tank flange provide a secure seal and allow cleaning without dead spaces.
Applications
Suitable for stirring systems in stainless steel reaction tanks and solution preparation tanks.
Key features
Zero leakage: a static seal using a welded containment shell replaces a dynamic mechanical seal to address leakage.
Easy maintenance: simple construction enables convenient disassembly, assembly and cleaning without cleaning dead spaces.
Efficient stirring: the bottom-mounted design can stir small quantities of material; the distinctive impeller accommodates different media.
Operating principle
The unit consists of inner and outer magnets, a containment shell and a drive motor. Parts in contact with the material use 316L/304 materials. A permanent-magnet coupling drives the stirring shaft. The rotating impeller creates a vortex, and centrifugal force circulates material against the tank walls to achieve homogenization, mixing, dissolution and dispersion.
Technical advantages
A shaft-seal-free magnetic-levitation drive uses a permanent magnetic field for contactless stirring, addressing shaft-seal leakage and wear, reducing maintenance costs and preventing material contamination. The intelligent variable-frequency system automatically adjusts speed according to viscosity, with mixing uniformity exceeding 99%, suitable for complex systems such as high-viscosity emulsions and suspensions.
