BMX Series Magnetic Drive Vortex Pumps

Product Description

The BMX Series (Vertical) Magnetic Drive Vortex Pump is a non-clogging pump developed by our company based on advanced foreign technology and market demand. It adopts a magnetic coupling drive design, completely eliminating dynamic mechanical seal leakage problems. With a fully vortex, open impeller and wide flow design, the clearance between the impeller and pump casing is equal to the discharge diameter. It is single-stage, single-suction, horizontally installed, with horizontal suction and tangential discharge. The pump features high efficiency, low vibration, smooth operation, and the impeller inlet stirs foreign objects, providing strong anti-clogging capability and excellent cavitation performance. It is especially suitable for handling particulate and fibrous media.

Applications include petrochemical, plastics, rubber, pulp & paper, metallurgy, sewage treatment, and other industries for conveying media containing large particles, fibers, sludge, or high gas content.

Design Features

• Innovative and practical structure design of the pump body and impeller creates a vortex flow inside the pump casing. Large, highly abrasive particles flow toward the center of the channel, while smaller, less abrasive particles contact the chamber and impeller surfaces, reducing wear and extending pump life.
• The impeller is of open type, with no gap requirement with the front cover (wear plate). Impeller clearance can reach 30–100 mm. Most solid particles bypass the impeller and are directly discharged, minimizing wear and reducing clogging risks.
• Even with minor wear on flow components, pump performance remains stable, significantly extending impeller lifespan.
• For crystallizing or precipitating media, the impeller structure delays scaling on the impeller surface.

Working Principle

When the impeller rotates, centrifugal force increases the energy of the medium. Fluid between the blades moves together with the impeller. Medium near the impeller outlet forms a direct flow due to greater centrifugal force, while the medium in the middle forms a circulation flow.

The medium flows out through the pump outlet, generating head. Solid particles and fibers in the medium gain energy through circulation flow. Most solids bypass the impeller and are discharged through the outlet, enabling the pump to handle complex or impurity-laden fluids.

Advantages:

1. Excellent non-clogging performance, capable of passing solid particles up to the size of the outlet diameter.
2. Most solid particles do not pass through the impeller, greatly extending impeller life.
3. Good suction and cavitation resistance.
4. Capable of pumping liquids with high gas content.
5. Capable of pumping high-concentration, high-viscosity liquids.
