Iwaki L-MX-F400RFAV Liquid End Only Magnetic Drive Pump Assembly
The Iwaki L-MX-F400RFAV is the liquid end assembly from Iwaki's MX-F series of magnetic drive pumps, built specifically for handling aggressive and corrosive fluids that would quickly wear down a standard polypropylene wet end. Because this is a "liquid end only" configuration, it ships without a motor, giving engineers and maintenance teams the flexibility to pair it with whatever motor already exists on their system or to standardize across multiple pump frames using a single spare part.
What sets this unit apart is its CFRETFE construction, a carbon fiber reinforced ETFE material chosen for its resistance to strong acids, oxidizers, and other chemically demanding media. Combined with an alumina ceramic bearing and spindle, a PTFE-lined mouth ring, and AFLAS o-rings rated for higher liquid temperatures, the L-MX-F400RFAV is designed to keep running reliably in plating lines, etching baths, chemical blending systems, and other processes where lesser materials would fail prematurely.
Because it's a sealless magnetic drive design, there's no mechanical shaft seal to leak or wear out, which cuts down on maintenance headaches and helps prevent hazardous chemical leaks. Facilities that need a dependable, drop-in replacement liquid end for their existing MX-F400 frame, or that are building a new system around a chemically resistant pump, will find this assembly matches the durability and performance Iwaki pumps are known for across a wide range of industrial applications.

FAQs
Q: Does the Iwaki L-MX-F400RFAV come with a motor?
A: No, this is a liquid end only assembly, meaning it includes the pump casing, impeller, and internal wetted components but does not include a motor. It is designed to be paired with a compatible motor separately.
Q: What makes the CFRETFE material different from standard polypropylene pump ends?
A: CFRETFE offers significantly better resistance to strong acids, oxidizers, and other aggressive chemicals compared to standard GFRPP construction, making it better suited for demanding chemical processing environments.
Q: Can this liquid end be used as a replacement part for an existing Iwaki MX-F400 pump?
A: Yes, it is designed to fit the MX-F400 frame and can serve as a replacement or upgrade for existing units using compatible motor and mounting configurations.
Q: Why choose a magnetic drive pump over a traditional seal-based pump?
A: Magnetic drive pumps eliminate the mechanical shaft seal entirely, which removes a common source of leaks and reduces the risk of hazardous chemical exposure, while also lowering long-term maintenance needs.
Q: Is this pump end suitable for high-temperature applications?
A: The AFLAS® o-rings used in this configuration are chosen specifically to extend the acceptable liquid temperature range compared to standard elastomers, making it a better fit for warmer process fluids.
