Product Description
Model Code Explanation
Product Introduction
CWB magnetic vortex chemical pump (hereinafter referred to as magnetic vortex pump) is a new pump that applies the working principle of a permanent magnet coupling to a centrifugal pump. With reasonable design and advanced manufacturing process, it features full sealing, zero leakage, low flow, high head and excellent corrosion resistance, reaching the advanced level of similar foreign products.
The magnetic pump adopts static sealing instead of dynamic sealing, so that all wetted parts of the pump are in a completely sealed state, thoroughly solving the problems of leakage that cannot be avoided by mechanical seals on other pumps.
CWB magnetic vortex chemical pump uses corrosion-resistant and high-strength engineering plastics, alumina ceramic and stainless steel as the main materials, thus providing excellent corrosion resistance and ensuring that the pumped medium is free from contamination.
Product Features
CWB magnetic vortex chemical pump adopts a magnetic drive structure, ensuring tight sealing of the pump and enabling leak-free transfer of corrosive, flammable, explosive and highly toxic chemical media.
1. High head and low flow, with a specific speed generally less than 40;
2. Simple structure, compact size and light weight;
3. CWB magnetic vortex chemical pump is equipped with a self-lubricating circulation loop to extend the service life of the sliding bearings;
4. A cooling circulation loop is added to remove eddy-current heat from the magnets in time;
5. CWB magnetic vortex chemical pump adopts cantilever blades to reduce the impeller radial force;
6. As the viscosity of the pumped medium increases, the pump efficiency drops sharply; therefore, the kinematic viscosity of the medium should not exceed 5×10⁻⁶ m²/s.
Product Applications
The magnetic pump is compact in structure, attractive in appearance, small in size, low in noise, reliable in operation, and convenient in use and maintenance. It is widely used in chemical, pharmaceutical, petroleum and other industries for pumping acids, alkalis, oils, rare and precious liquids, toxic liquids and volatile liquids, as well as in supporting circulation water systems and filter units. It is particularly ideal for handling liquids that are prone to leakage, flammable or explosive.
