Iwaki MX-403CV6 Polypropylene Mag Drive Pump End
The Iwaki MX-403CV6 is a seal-less centrifugal magnetic drive pump end built for demanding chemical handling work. Because the magnetic coupling eliminates the shaft seal entirely, there's no packing to wear out and no seal to leak, which makes this pump a favorite for facilities that can't afford unplanned downtime or fluid loss. The polypropylene construction stands up well against a wide range of acids, caustics, and other aggressive chemicals, so it fits naturally into settings like chemical recirculation loops, scrubber systems, plating lines, and general chemical transfer work.
This is a pump end only, meaning it ships without a motor and is designed to pair with a standard 3 HP, 3450 RPM, 145TC NEMA frame motor. That setup gives plant engineers flexibility to match the pump to whatever motor configuration already fits their system, rather than being locked into a single fixed unit. Inside, the carbon bearing and alumina ceramic spindle are built to handle the friction and heat that come with continuous duty, while the self-lubricating design relies on the pumped liquid itself to keep moving parts cool, so priming before startup really matters.
For anyone maintaining or replacing pump ends in chemical processing environments, the MX-403CV6 offers a dependable, low-maintenance option that keeps things running without the constant seal inspections that traditional pumps require. It's a practical choice for teams looking to standardize on a rugged, chemically resistant pump platform across multiple applications.

Frequently Asked Questions
Q: Does the MX-403CV6 come with a motor included?
A: No, this is a pump end only. It requires a separately purchased 3 HP, 3450 RPM, 145TC frame motor.
Q: Can this pump run dry for any length of time?
A: No. The pump is not self-priming and relies on the pumped liquid for lubrication and cooling, so running it dry can cause seizure and rapid wear.
Q: What chemicals is this pump suitable for?
A: The GFRPP casing and impeller offer broad resistance to many acids, caustics, and industrial chemicals, though a chemical resistance chart should be checked for specific fluids and temperatures.
Q: How often can this pump be started and stopped?
A: Start/stop frequency should be limited to no more than six times per hour to avoid premature pump damage.
Q: Can this pump handle slurries or liquids with solids?
A: No, this pump is not designed for slurries, and performance can be affected by the viscosity and specific gravity of the liquid being pumped.
