Iwaki MX-F250CFVX 1x1 ETFE Mag Drive Pump End, Less Motor
If you're moving aggressive chemicals through your process line, the Iwaki MX-F250CFVX gives you a pump end built to handle it without the wear and tear that ruins metal alternatives. It's a seal-less magnetic drive centrifugal pump end, so there's no shaft seal to leak, and the wetted parts are made from high-grade ETFE, one of the most chemically resistant plastics available. That combination makes it a popular choice for plating lines, etching baths, chemical blending, filtration loops, and general transfer work where the fluid being pumped simply cannot come into contact with metal.
What sets this particular configuration apart is the CF bearing system, which is engineered to survive brief periods of dry running, closed-valve conditions, or cavitation without immediately destroying the internals. Add to that the split volute casing design, which reduces internal recirculation losses and pushes more of that flow efficiently out the discharge port, and you get a pump end that's both tougher and more efficient than older single-casing designs. It ships as a pump end only (less motor), with 1 inch by 1 inch NPT suction and discharge ports sized to fit a standard 56C frame motor, so you can pair it with the motor you already have or one that matches your voltage and enclosure requirements.

Frequently Asked Questions
Q: Does the MX-F250CFVX include a motor?
No, this model is sold as a pump end only. It's designed to be paired with a compatible 56C frame motor.
Q: What makes the CF bearing system different from a standard bearing?
The CF bearing system is built to tolerate brief periods of dry running, cavitation, or operation against a closed discharge valve without the immediate damage a standard bearing setup would suffer.
Q: What chemicals is ETFE resistant to?
ETFE offers strong resistance to a wide range of acids, bases, and solvents, which is why it's used in aggressive chemical transfer and processing applications, though specific chemical compatibility should be verified against a resistance chart for your exact fluid.
Q: Can this pump run in a self-priming setup?
No, this is a flooded suction pump. If you need suction lift capability, Iwaki's SMX series is the self-priming equivalent of this design.
Q: What industries typically use this pump end?
It's commonly used in chemical processing, metal finishing and plating, semiconductor and electronics manufacturing, water treatment, and general industrial fluid handling, not just marine or maritime applications.
