Serie MDW

Product catalog summary

Overview: The IWAKI MDW series represents the largest class of fluoroplastic magnetic drive pumps globally, designed for high efficiency and durability in chemical process applications. These pumps are suitable for chemical transfer, recirculation, and scrubber liquid recirculation, offering a robust alternative to conventional sealed pumps.

Specifications: The MDW series features a maximum flow capacity of 300 m³/hr and a maximum discharge head of 98 meters. The pumps are constructed with fluoroplastic and fine ceramic wetted parts, providing high chemical resistance. The robust structure includes high-strength ductile cast iron external armor and a unique rear casing design for high casing pressure resistance.

Design and Maintenance: The MDW pumps incorporate a back pullout system for easy maintenance and inspection without removing pipework. They are ISO compliant, ensuring dimensional compatibility with international standards and interchangeability with conventional sealed centrifugal pumps.

Materials and Construction: Key components include PFA, ETFE, CFRETFE for the wet-end materials, and SiC for the bearing/sleeve. The pumps are available in various configurations, including different motor types and outputs, with options for special versions and drain configurations.

Performance Curves: The document provides performance curves for different models (MDW50, MDW80, MDW100) at 50Hz, illustrating the relationship between capacity and head.

Dimensions: Detailed dimensions are provided for each pump model, highlighting the size and configuration options available.

Safety and Legal Considerations: Users are advised to read the instruction manual carefully for safe use. The document also notes that export licenses may be required due to international export control regulations.

Additional Series: The document briefly mentions other series such as MXM, MDE, and MDM, each with specific features and performance metrics suitable for various industrial applications.
