Why Chemical Industry

Safe Transfer of Aggressive Chemicals · Heavy-Duty Corrosion-Resistant Pumping Technology

Chemical production involves a wide range of challenging fluids, from strong acids and alkalis to solvents, polymers, and temperature-sensitive chemicals. Meibao provides reliable pumping solutions for chemical processing, petrochemicals, and fine chemicals, covering applications from tank unloading and reactor feeding to chemical dosing and circulation.

Our MB-F fluoroplastic pumps, MB-MD magnetic drive pumps, and MB-D diaphragm metering pumps are designed for demanding conditions such as high corrosion, high temperature, toxic media, and precise dosing. High-purity wetted parts, low-dead-leg flow paths, and zero-leakage designs help improve safety, cleanliness, and process reliability while reducing maintenance and contamination risks.

The Challenge

Why Chemical Pumping Requires More Than Corrosion Resistance

Chemical processes involve corrosive, high-temperature, toxic, and contamination-sensitive media. Pumps must withstand harsh operating conditions while minimizing leakage, emissions, and residual contamination.

High Corrosion + High Temperature

Concentrated acids, oleum, and hot chlorine can cause severe corrosion, even in specialty alloys. Chemical pumps must handle both highly corrosive media and high temperatures without compromising service life or process stability.

VOC & Toxic Gas Emissions

Mechanical seal leakage can release hazardous chemicals such as benzene, toluene, and chloroform. Chemical plants need reliable sealing solutions to minimize leakage, VOC emissions, and operator exposure.

Cleaning & Batch Changeover

Dead-leg areas can trap chemical residues, making cleaning slow and difficult. Strict processes require low residual volume and low contamination levels to ensure fast, reliable, and repeatable batch changeover.

Meibao Solutions

Engineered for Corrosion Resistance, Zero Leakage & Easy Cleaning

Meibao combines advanced materials, sealed-drive technology, and sanitary flow-path design to address the toughest chemical pumping challenges. From high-temperature corrosive fluids to toxic media and strict cleaning requirements, our pump solutions are designed for safer, cleaner, and more reliable operation.

Ultra-Thick Liner + Specialty Alloy Protection

MB-F Series uses 6.0–8.0 mm FEP/PFA liners with Hastelloy C-276 or titanium components for harsh corrosive and high-temperature media. Corrosion rate can be below 0.01 mm/year in 98% H₂SO₄ at 50°C, with a design life of up to 87,600 hours.

Zero-Leakage Magnetic Drive + Dual Containment

MB-MD Series uses a fully sealed magnetic drive with optional dual containment and pressure monitoring. It helps prevent media leakage and reduce VOC emissions by ≥99.8%, while achieving up to 92%–96% magnetic drive efficiency.

Zero-Dead-Leg Design + SIP/CIP

MB-MD-S Series features a sanitary zero-dead-leg flow path with residual volume ≤8 mL, plus standard SIP/CIP capability. It delivers TOC ≤0.5 ppm, while reducing batch changeover cleaning time by up to 58% and water consumption by 42%.

Wastewater & Exhaust Gas Treatment Vietnam

Anti-Clogging Self-Priming Pump for Wastewater Lifting: 380 L/min Stable Flow, 0 Leakage, Annual Savings

The Problem

Vinh Hao Industrial Wastewater Treatment Station is located in an industrial park in Vietnam. It is responsible for treating industrial wastewater from several factories in the park. One of the key processes is the wastewater lifting system, which transfers industrial wastewater collected in the equalization tank to the downstream biological treatment units.

Our Solution

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.

The Result

Since installation and commissioning were completed in December 2025, the 8 MA-50032L self-priming pumps at Vinh Hao Wastewater Treatment Station have operated continuously for more than 8 months.
