Iwaki MX-403HCV6 2" x 1.5" Magnetic Drive Pump End
Iwaki's MX-403HCV6 is a high-pressure, sealless magnetic drive pump end built for demanding chemical and industrial fluid transfer jobs. Because there's no mechanical shaft seal, there's nothing to wear out or leak, which makes this pump a smart choice for aggressive chemicals like bleach and sulfuric acid where a traditional seal would eventually fail. The GFRPP casing and impeller stand up to a wide range of corrosive fluids, while the carbon bearing and alumina ceramic spindle keep things running smoothly even when things get demanding.
What really sets this pump apart is its self-radiating design. Iwaki engineered the impeller and magnet capsule with built-in heat dispersion holes that keep fluid circulating around the bearing and spindle, so heat from friction doesn't build up and warp components over time. That also means the pump can handle brief spells of dry running without immediately damaging itself, which is a nice safety net for real-world operating conditions. It mounts to a standard NEMA 145TC frame motor, so it's straightforward to pair with equipment you likely already have on hand.
This listing is for the pump end only, so you'll need to supply your own 3 HP, 3450 RPM, 145TC frame motor to complete the assembly. It's an ideal fit for facilities running filtration, spraying, washing, plating, chemical blending, or surface treatment processes that call for a rugged, corrosion-resistant, low-maintenance pump.

Frequently Asked Questions
Q: Does the MX-403HCV6 include a motor?
A: No, this is a pump end only. It requires a separately purchased 3 HP, 3450 RPM, NEMA 145TC frame motor to operate.
Q: Can this pump handle aggressive chemicals like bleach or acids?
A: Yes, its GFRPP construction and FKM O-ring make it well suited for transferring corrosive chemicals such as bleach and sulfuric acid.
Q: What happens if the pump runs dry for a short period?
A: The carbon bearing and self-radiating structure are designed to tolerate brief dry running without immediate damage, though sustained dry running should still be avoided.
Q: Why choose a magnetic drive pump over a traditional sealed pump?
A: Magnetic drive pumps have no mechanical shaft seal, removing a common failure and leak point, which reduces maintenance and improves reliability with hazardous or corrosive fluids.
Q: Is this pump only used in marine settings?
A: No, it's an industrial process pump commonly used in manufacturing, chemical processing, plating, and water treatment applications well beyond marine use.
