Iwaki MX-402HCV6 Mag Drive Pump End
The Iwaki MX-402HCV6 is a sealless, non-metallic magnetic drive pump end built for facilities that need dependable fluid transfer without the leak risk of a mechanical seal. Its glass-filled polypropylene casing and Viton o-rings make it a natural fit for aggressive chemicals, including bleach and sulfuric acid, while the carbon and alumina ceramic bearing and spindle assembly keep the pump running smoothly under demanding conditions. This is a pump end only, so it pairs with a standard NEMA frame motor for a complete, easy-to-install system.
What sets this pump apart is the self-radiating structure built into its design. That engineering allows the pump to tolerate brief periods of dry running and helps it resist cavitation, even when working against a closed discharge valve. The split volute casing forms a vortex chamber that guides fluid efficiently toward the discharge port, reducing internal recirculation and improving overall performance. Whether the application involves filtering, spraying, washing, plating, or general chemical transfer, this pump end is engineered to hold up over the long haul.
Because it's not limited to one industry, the MX-402HCV6 shows up across surface treatment lines, chemical blending operations, and general industrial process work. Its non-corroding, non-metallic construction means it can be installed indoors or outdoors without concern for a corroding baseplate, and its compatibility with standard motor frames keeps replacement and setup straightforward for maintenance teams.

Frequently Asked Questions
Q: Does the Iwaki MX-402HCV6 come with a motor?
A: No, this is a pump end only. It's designed to be paired with a standard NEMA frame motor, which is sold separately.
Q: What makes this pump suitable for corrosive chemicals?
A: The GFRPP casing and Viton o-rings resist attack from aggressive fluids like bleach and sulfuric acid, and the sealless magnetic drive design removes the leak path that a traditional mechanical seal would create.
Q: Can this pump run dry for any period of time?
A: The self-radiating structure allows for brief periods of dry running when the pump is fitted with a carbon bearing, though sustained dry running should still be avoided.
Q: Is this pump limited to marine use?
A: No, this pump end is used across a wide range of industrial settings, including chemical processing, plating, surface treatment, and general fluid transfer applications, not just marine environments.
Q: How is the MX-402HCV6 different from the standard MX-402CV6?
A: The "H" designation typically indicates a higher head version within the MX-402 lineup, giving it a different performance curve than the standard CV6 model while sharing the same materials of construction.
