Iwaki MX-F401CFVX Magnetic Drive Pump End
The Iwaki MX-F401CFVX is a rugged, sealless magnetic drive pump end built for facilities that can't afford leaks or downtime. Instead of relying on a traditional shaft seal, this pump uses magnetic coupling to move fluid, meaning there's no wearable seal to fail and no drip path for aggressive chemicals to escape through. The CFRETFE casing and impeller, paired with FKM O-rings and a high-density carbon bearing riding on an alumina ceramic spindle, give this pump the chemical resistance and durability needed for demanding transfer and recirculation work.
What makes this pump especially practical is how it handles real-world operating conditions. Its self-radiating design channels pumped liquid around the bearing and spindle to draw heat away from moving parts, helping the pump tolerate brief dry-running events without seizing prematurely. Because it's a pump end only, it pairs with a standard NEMA 56C frame, 1-1/2 HP, 3450 RPM motor, giving buyers flexibility to source or reuse compatible motors instead of being locked into a proprietary drive package.
Facilities running chemical transfer lines, plating baths, scrubbers, or precision cooling loops rely on pumps like the MX-F401CFVX because consistency matters as much as raw performance. With 1.5-inch NPT inlet and outlet ports and flow capacity reaching into the 75 GPM range, this pump end fits comfortably into mid-size industrial systems where reliable, seal-free chemical handling is non-negotiable.

Frequently Asked Questions
Q: Does the Iwaki MX-F401CFVX include a motor?
A: No, this is a pump end only. It requires a separately purchased 1-1/2 HP, 3450 RPM, NEMA 56C frame motor to operate.
Q: How much dry running can this pump handle?
A: It can tolerate brief dry-running periods thanks to its carbon bearing and self-radiating design, but extended dry running causes seizure and part wear, so priming before startup is essential.
Q: What liquids can this pump handle?
A: It's built for chemical transfer and recirculation of compatible fluids based on its CFRETFE and FKM wetted materials, but it cannot handle liquids containing slurry.
Q: Is there a limit on how often the pump can be started and stopped?
A: Yes, frequent cycling should be limited to no more than six start/stop cycles per hour to prevent premature damage.
Q: Does this pump self-prime?
A: No, the MX-F401CFVX is not self-priming and must be manually primed with the pumped liquid before each initial startup.
