Product Dewspiption
The Meibao MMF Series is a revolutionary permanent magnet direct drive magnetic pump that sets new standards for energy efficiency, compactness, and quiet operation. Featuring a beyond-IE5 efficiency motor with frequency conversion control, this series delivers significant energy and cost savings compared to traditional pump designs. The lightweight, fully encapsulated plastic housing provides IP66 protection and exceptional corrosion resistance. With a super-quiet, fanless cooling design, the MMF Series is specifically engineered for cleanroom environments and applications with strict temperature and humidity requirements, making it the ideal choice for semiconductor, pharmaceutical, and high-purity chemical processing.
Energy-Saving & High-Efficiency Design
Equipped with a beyond-IE5 efficiency motor and frequency conversion control, delivering substantial energy savings and reduced operating costs compared to conventional pump systems.
Super-Quiet Operation
Fanless cooling design ensures minimal noise levels and low temperature rise, making the MMF Series ideal for noise-sensitive environments such as cleanrooms, laboratories, and semiconductor fabrication facilities.
High Protection & Corrosion Resistance
Integrated, fully encapsulated plastic housing provides IP66 protection against dust and water ingress. Constructed from high-performance materials including GFRPP, CFRPP, PVDF, and ETFE, offering excellent resistance to aggressive chemicals.
Lightweight & Compact Design
Embedded, modular component design results in a lightweight, space-saving footprint that simplifies installation and integration into existing equipment.
100% Leak-Free Magnetic Drive
The sealless magnetic coupling eliminates the risk of leakage, protecting operators and the environment while reducing maintenance costs.
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.
