Iwaki MX-402CV6 Mag-Drive Centrifugal Pump End, 145TC Frame, Less Motor
Fluid handling systems that deal with aggressive chemicals need equipment built to avoid leaks at the source, and that's exactly where the Iwaki MX-402CV6 earns its keep. This is a magnetic drive centrifugal pump end designed without a mechanical shaft seal, which means there's no seal to wear out, weep, or eventually fail under pressure. The casing and impeller are made from glass fiber reinforced polypropylene, giving the pump strong resistance to a wide range of corrosive fluids while keeping the unit lightweight and easy to service. Inside, a high-density carbon bearing and an alumina ceramic spindle work together to handle friction and heat, even tolerating brief dry-running conditions without damage.
What makes this pump end particularly practical is its use of a standard NEMA 145TC frame, so it pairs with a readily available 2 HP, 3450 RPM motor rather than requiring a specialty drive unit. The internal magnet design is engineered to keep the rear thrust surface and bearing from grinding against each other during operation, and built-in heat dispersion holes help circulate fluid around the spindle to carry heat away efficiently. That combination reduces wear over time and helps the pump hold up under continuous duty. It's a solid choice for chemical transfer, chemical re-circulation, and scrubber system applications where reliability and corrosion resistance both matter.
Because this unit ships as a pump end only, it's best suited for facilities replacing an existing IWAKI MX-series pump end or building out a system where the motor is sourced separately. The FKM O-ring seals are compatible with a broad range of process chemicals, rounding out a pump end that's built for demanding industrial and chemical-handling environments.

Frequently Asked Questions
Q: Does the Iwaki MX-402CV6 come with a motor included?
A: No, this model is a pump end only. It requires a separately sourced 2 HP, 3450 RPM, 145TC frame motor to operate.
Q: What makes a magnetic drive pump end different from a standard seal pump?
A: A magnetic drive pump end transfers rotational energy through magnets rather than a mechanical shaft seal, which removes a common leak point and reduces maintenance needs over time.
Q: Can the MX-402CV6 handle brief dry-running without damage?
A: Yes, the carbon bearing and self-radiating design are built to tolerate short periods of dry running without significant wear.
Q: What fluids is this pump end suitable for?
A: The GFRPP casing and FKM O-rings make it well suited to a broad range of corrosive and industrial process chemicals, though compatibility should be checked against the specific fluid in use.
Q: Is a specialty motor needed to run this pump end?
A: No, it's designed around a standard NEMA 145TC frame, so a commonly available 2 HP, 3450 RPM motor of that frame size will work.
