Product Dewspiption

The Meibao MFR Series Chromic Acid Chemical Liquid Filter is a specialized filtration solution engineered specifically for the unique challenges of chromic acid and other strong oxidizing, highly corrosive chemical baths. Chromic acid presents severe corrosion and contamination risks to standard filtration equipment. The MFR series addresses these pain points through an all-non-metallic construction using premium UPVC and PVDF materials, ensuring no metal ions leach into the solution and no corrosion-induced failure occurs. Combined with a filter cartridge nut-type sealing design for zero leakage and an idling-capable pump that tolerates dry-running conditions, this filter provides reliable, high-purity filtration for demanding chrome plating, PCB etching, and surface treatment processes.

Full Non-Metallic Construction

The filter chamber is constructed entirely from UPVC and PVDF materials with no metal components in contact with the solution, preventing metal ion contamination and ensuring high-purity chromic acid filtration.

Superior Anti-Corrosion & Anti-Oxidation
UPVC/PVDF materials offer exceptional chemical stability, withstanding long-term exposure to chromic acid and other strong oxidizing chemicals without swelling, embrittlement, or dissolution.

Zero Leakage Sealing System
The filter group utilizes a cartridge nut-type locking design with VITON rubber seals, ensuring each cartridge is independently sealed for zero leakage, eliminating the risk of hazardous chemical spills.


Idling Capable Pump
Equipped with a specially designed corrosion-resistant pump that can run dry without damage, accommodating fluctuating liquid levels and intermittent operation without risking pump burnout.


High Precision Filtration
Compatible with various filter materials including filter paper, filter cartridge lock-cap, and filter bag types, providing flexible precision options for different filtration requirements.

Typical Applications

Chrome Plating: Filtration of chromic acid baths for decorative and functional chrome plating.
PCB Manufacturing: Etching solution filtration and purification.
Surface Treatment: Passivation and conversion coating solution filtration.
Metal Finishing: Chromic acid anodizing and bright dipping solution maintenance.

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.
