Product Dewspiption

The Meibao MFL/MFX Series High Precision Chemical Liquid Filter is a professional-grade filtration solution engineered for electroplating solutions, chemical baths, and industrial fluid purification requiring superior precision. Featuring a two-stage progressive filtration design, this series combines primary coarse filtration with secondary deep filtration (activated carbon or precision cartridge), achieving impurity removal rates exceeding 98%. The filter barrel is manufactured through one-piece injection molding with no welding points, ensuring 100% leak-free operation and exceptional corrosion resistance. With blind-hole cartridge design providing wide filtration area and high efficiency, this series is widely used for chromic acid, nickel plating, acid copper, alkaline zinc, and other demanding electroplating applications.

Two-Stage Progressive Filtration

Dual-barrel series connection design: the first barrel performs primary interception of large particles and impurities, while the second barrel enables activated carbon adsorption or micron-level precision filtration, achieving deep purification in one step.

100% Leak-Free One-Piece Molding
The filter barrel is manufactured through integrated injection molding with no welding points or pores, fundamentally eliminating leakage risks and ensuring long-term reliable operation.

Superior Corrosion Resistance
Available in high-quality PP, FRPP, or PVDF materials with thick-walled construction, providing excellent resistance to strong acids, alkalis, and aggressive chemicals. Service life up to 8-10 years.
High Precision Filtration

Blind-hole cartridge design provides wide filtration area with precision down to 1μm, effectively removing particles, decomposition products, and suspended solids.

Intelligent Overload Protection
Equipped with precision intelligent overload protection switch that monitors current and load status in real-time, automatically cutting power during abnormal conditions to prevent motor burnout.

Typical Applications

Electroplating Industry: Filtration of plating solutions including acid zinc, alkali zinc, hardware acid zinc, and basic copper.
Surface Treatment: High-precision chemical bath filtration.
PCB Manufacturing: Etching and developing solution filtration.
Chemical Processing: Corrosive chemical liquid purification and recovery.

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.
