Product Dewspiption

The Meibao MZK Series Stainless Steel Centrifugal Pump is a high-performance, corrosion-resistant pumping solution engineered for demanding chemical transfer applications. Constructed from premium SUS304 or SUS316 stainless steel, this series offers excellent resistance to a wide range of acids, alkalis, and aggressive chemicals.

Featuring a self-cooling design with a cooling water tank, the MZK series can run idle (dry) without damaging mechanical seal components, significantly enhancing operational reliability.

With a direct-coupled coaxial structure, fluid mechanics-optimized impeller, and low-noise stainless steel bearings, this series delivers high efficiency, stable performance, and long service life for industrial chemical processing, wastewater treatment, and surface finishing applications.

Idling Capable with Self-Cooling Design

Equipped with a cooling water tank that keeps the mechanical seal continuously immersed in coolant, the pump can operate dry (idle) without damage to seal components, reducing maintenance costs and downtime.

Corrosion-Resistant Stainless Steel Construction
Available in SUS304 and SUS316 stainless steel, providing exceptional corrosion resistance for handling strong acids (up to 98% concentration), alkalis, and various chemical media.

High-Efficiency Direct-Coupled Design
Features a coaxial direct-coupled structure (motor shaft as pump shaft) with excellent concentricity, reducing vibration, noise, and energy loss while improving overall efficiency.
Optimized Hydraulic Performance

Engineered with fluid mechanics principles and a scientific hydraulic impeller model, delivering stable performance, high flow rates, and low noise operation.

Low Maintenance & Long Service Life
Utilizes stainless steel bearings with low vibration and noise, plus mechanical seal design that does not damage the shaft, ensuring long service life and easy maintenance.

Typical Applications

Chemical Processing: Transfer and circulation of acids, alkalis, and aggressive chemicals.
PCB Manufacturing: Etching and developing solution transfer.
Metal Surface Treatment: Chemical baths and cleaning solutions.
Electroplating Industry:Plating solution transfer and circulation.
