Iwaki MX0400 Magnet Drive Pump (Part Number MX0400)
The Iwaki MX0400 is a heavy-duty magnet drive pump built to keep tough, corrosive, or hazardous fluids fully contained. Instead of relying on a mechanical shaft seal, it uses a ferrite magnet coupling to transfer power to the impeller, so there's no seal to wear out and no path for the fluid to leak out over time. That design makes it a dependable choice for plants that move aggressive chemicals day in and day out, since operators don't have to worry about seal replacement schedules or the safety risks that come with a leaking pump.
This pump is set up to work with a standard NEMA frame motor, which makes installation, replacement, and long-term maintenance much simpler than pumps that require specialized or proprietary motors. Its GFRPP wet end resists a wide range of corrosive chemicals, while the alumina ceramic shaft and bearing options add durability in demanding service. The split volute casing improves flow efficiency and helps the pump handle brief dry-run conditions or a closed discharge valve without the kind of damage that would sideline a conventional centrifugal pump.
Whether it's supporting a multi-unit chemical feed system, a long supply line, or an elevated process loop, the MX0400 is engineered to run continuously with minimal fuss. It's a practical fit for facilities that need reliable, low-maintenance fluid transfer without sacrificing safety or performance.

Frequently Asked Questions
Q: Does the Iwaki MX0400 pump come with a motor included?
A: Some configurations include a NEMA motor, while others are sold as head-only units. Confirm the specific configuration before ordering if a motor is required.
Q: Can the MX0400 run dry without damage?
A: It can tolerate brief periods of dry running thanks to its self-radiating structure, but extended dry running is not recommended and can cause premature wear.
Q: Is the MX0400 self-priming?
A: No, this pump requires a flooded suction installation. For self-priming needs, the SMX series is the equivalent alternative.
Q: What chemicals is the MX0400 suitable for?
A: Its GFRPP wet end and ferrite magnet coupling make it suitable for a wide range of corrosive and hazardous chemicals, including bleach and sulfuric acid.
Q: How should the MX0400 be mounted?
A: It should always be mounted horizontally and can be installed either indoors or outdoors with adequate surrounding clearance.
