MNX Series Magnetic Drive Pump

Product Dewspiption

The Meibao MNX Series is a state-of-the-art magnetic drive pump engineered for the safe, reliable, and efficient transfer of corrosive, toxic, and high-purity fluids. By utilizing advanced magnetic coupling technology, the MNX Series completely eliminates the need for dynamic shaft seals, ensuring zero leakage and significantly reducing maintenance costs and environmental risks. Its compact design and wide range of corrosion-resistant materials make it the ideal solution for demanding applications across the chemical, pharmaceutical, electronics, and metal finishing industries.

Key Features

100% Leak-Free Magnetic Drive

The magnetically driven, sealless design eliminates leakage and emissions, providing a safer and cleaner working environment while protecting your pump from damage caused by dry running.

Superior Corrosion Resistance
Constructed from high-performance materials including GFRPP, CFRPP, PVDF, and ETFE. This ensures exceptional resistance to a broad spectrum of acids, alkalis, and solvents, guaranteeing a long service life even in the harshest chemical environments.

High-Efficiency & Energy-Saving

Features a nano-technology rear magnet for strong magnetic force and high efficiency. The spiral volute casing design reduces internal friction and noise, optimizing hydraulic performance and reducing energy consumption.

Robust & Durable Construction

Engineered with a rugged design that includes a thrust ring to control the axial position of the impeller and prevent the bearing from contacting the rear thrust ring during idling. This minimizes frictional heat and ensures consistent lubrication for long-lasting, maintenance-free operation.

Wide Range of Applications

The MNX Series is suitable for a diverse range of applications, from chemical transfer and electroplating to wastewater treatment and semiconductor manufacturing, offering a versatile solution for various industrial fluid handling needs.

What is the maximum viscosity the MB pump can handle?

The MB magnetic drive pump is optimized for low-to-medium viscosity liquids (up to ~200 cPs at operating temperature). For high-viscosity media above 200 cPs, please contact our engineering team — we may recommend a reduced speed operation or a gear pump alternative.

Can the MB pump handle HF acid?

Yes. The MB pump with PTFE or PVDF wet-end is fully compatible with hydrofluoric acid at concentrations up to 50% and temperatures up to 80°C. PTFE offers the best HF resistance. For semiconductor-grade HF applications, we recommend our dedicated HF Series with ultra-pure material specifications.

What is the pump's NPSH requirement?

NPSH requirements vary by model and operating point. Typically, the MB series requires 2-3m NPSHa. We recommend ensuring the available NPSH (NPSHa) from your installation is at least 1m higher than the pump's required NPSHr. Full NPSH curves are available in the product datasheet.

Do you offer ATEX / explosion-proof versions?

Yes. ATEX Zone 1 and Zone 2 certified models are available for environments where flammable gases or vapors may be present. Please specify the ATEX zone and gas group (IIA, IIB, or IIC) when requesting a quote.

Can I get spare parts for this pump?

Yes. We stock a comprehensive range of spare parts for the MB series including magnet assemblies, impellers, shaft sleeves, and containment shells. Parts can be shipped within 5-10 working days to most destinations. We recommend ordering a spare parts kit with your initial order for critical applications.
