Iwaki MX-F400CFVX Mag-Drive Pump End (Less Motor)
For facilities that move aggressive or sensitive fluids day in and day out, the Iwaki MX-F400CFVX brings a level of dependability that's hard to overstate. Built as a non-metallic magnetic drive pump end, it eliminates the shaft seal entirely, which means no seal to wear out and no risk of the leaks that often come with traditional centrifugal pumps. That design choice alone makes it a favorite in plating lines, chemical blending operations, and filtration setups where downtime simply isn't an option.
What really sets this pump apart is how it handles the tough moments most pumps struggle with. Thanks to its self-radiating structure and non-contact spindle design, the MX-F400CFVX can tolerate brief dry-running conditions and keep working even when a discharge valve closes unexpectedly or suction conditions turn less than ideal. Its split volute casing forms a vortex chamber that reduces internal recirculation, so the pump keeps its efficiency even under demanding process loads.
Sold as a pump end without a motor, the MX-F400CFVX pairs easily with standard NEMA frame motors, giving engineers and maintenance teams flexibility when specifying or replacing equipment. Whether it's handling bleach, sulfuric acid, or other corrosive chemistries, this pump end delivers the kind of steady, low-maintenance performance that keeps production lines running smoothly.

Frequently Asked Questions
Q: Does the Iwaki MX-F400CFVX come with a motor included?
No, this pump end is sold less motor. It is designed to be paired with a standard NEMA frame motor selected separately based on the application's power requirements.
Q: Can the MX-F400CFVX run dry for any period of time?
When fitted with a carbon bearing, the pump's self-radiating structure allows for brief periods of dry running, though extended dry operation is not recommended for any magnetic drive pump.
Q: What orientation should this pump be installed in?
The MX-F400CFVX should always be mounted horizontally to ensure proper bearing lubrication and operational stability.
Q: Is this pump only suitable for marine use?
No. While it is used in marine applications, the MX-F400CFVX is a versatile industrial pump end suited to chemical processing, plating, filtration, and general fluid transfer across many industries.
Q: What happens if the discharge valve is accidentally closed during operation?
The non-contact magnetic drive design helps the pump withstand running against a closed discharge valve for short periods without sustaining damage, thanks to its cavitation-resistant spindle support.
