Ultra-Pure Chemical Delivery Systems · Semiconductor-Grade Precision Pumping Technology
Electronics and semiconductor manufacturing requires pumps with high cleanliness, chemical resistance, and stable performance. Meibao pumps are designed for demanding processes such as copper electroplating, chemical circulation, and wet cleaning, handling chemicals including TMAH, acids, alkalis, and plating solutions.
For PCB etching, stable flow and spray pressure are essential for consistent etching quality. Meibao corrosion-resistant centrifugal and metering pumps provide reliable chemical circulation and precise dosing for acidic and alkaline etchants.
In photovoltaic manufacturing, processes such as wafer texturing, edge isolation, and quartz tube cleaning involve highly corrosive chemicals such as HF, HNO₃, and KOH at elevated temperatures. Meibao vertical sump pumps and magnetic drive pumps provide corrosion resistance, stable operation, and leak-free chemical handling for wet-process equipment.
Key Challenges in Electronics & Semiconductor Fluid Handling
Electronics and semiconductor processes require extremely clean, stable, and reliable fluid handling. From trace metal contamination to chemical corrosion, flow pulsation, and temperature drift, even small variations can affect process quality and production yield. Meibao focuses on these critical challenges with high-purity, corrosion-resistant, and precisely controlled pumping solutions.
Advanced Pumping Solutions for Critical Wet Processes
Meibao provides high-purity pumping solutions designed to address the most demanding requirements in electronics and semiconductor manufacturing. From ultra-clean fluoropolymer flow paths to advanced anti-permeation sealing and precise VFD control, our solutions help maintain chemical purity, prevent leakage, and ensure stable process performance.
For HF and hot HCl service, MB-F pump liners are thickened to 8.0 mm (vs. standard 6.0 mm) with an additional 0.2 mm ETFE barrier layer—HF permeation rate reduced to < 0.01 g·mm/(m²·day). Static seals use Kalrez® 6375 perfluoroelastomer O-rings (rated to +240°C); dynamic sealing utilizes contactless magnetic coupling or dual mechanical seals with barrier fluid—zero leakage recorded over 8,000 hours continuous testing in 49% HF at 90°C.
All MB-MD Series pumps are standard with PMSM (permanent magnet synchronous motors) + closed-loop vector control—flow regulation accuracy ±0.3% with response time < 50 ms. Impellers feature 7 backward-curved vanes with outlet angle 25°–30°—CFD-optimized flow pulsation reduced to ±0.8% (a 75% reduction vs. conventional pumps). The integrated PID temperature compensation module maintains plating bath temperature within ±0.3°C across –5°C to +85°C range.

The customer's three main problems—clogging, leakage, and self-priming failure—were closely connected:
• To prevent clogging, the impeller needs wide flow passages that can handle solid particles.
• To prevent leakage, the traditional shaft seal needs to be removed.
• To ensure reliable self-priming, the pump needs strong air-water separation and self-priming capability.
