Product Dewspiption

The Meibao MGM/MGB Series Mechanical Diaphragm Metering Pump is a precision-engineered dosing solution designed for accurate and reliable chemical injection in water treatment, chemical processing, and industrial applications. Featuring a mechanically driven diaphragm with no diaphragm protection plate on the material side, this pump ensures smooth material passage and minimal clogging risk. The variable eccentric mechanism guarantees smooth flow pulsation, while the enhanced structural design and wear-resistant ball bearings ensure stable operation even in harsh environments. Available in PVC, PVDF, and 316SS wetted materials with PTFE diaphragms, the MGM/MGB series offers exceptional corrosion resistance and versatility for handling a wide range of chemicals, including high-viscosity and slurry media.

Precise Dosing Control

Mechanical diaphragm design with 30%-100% adjustment range and ±1% static accuracy, ensuring precise and repeatable chemical dosing.

Smooth Flow Pulsation
Variable eccentric mechanism adjustment ensures smooth flow pulsation, minimizing pressure fluctuations and improving process stability.

Enhanced Structural Design
Reinforced construction suitable for harsh operating environments, with wear-resistant ball bearings for more stable operation and extended service life.
Oil Bath Lubrication

Drive components are lubricated in an oil bath, significantly extending service life and reducing maintenance requirements.

Flexible Adjustment Options
Flow can be adjusted in both shutdown and running states, with manual, electric, or variable frequency adjustment methods available.

Typical Applications

Water Treatment: Chemical dosing for pH adjustment, disinfection, and flocculation.
Chemical Processing: Precise injection of additives, catalysts, and reagents.
Petrochemical: Dosing of corrosion inhibitors and process chemicals.
Pharmaceutical: Accurate metering of active ingredients.
