Iwaki MX-401CV7 Mag Drive Centrifugal Pump End (No Motor)
Businesses that move corrosive or hard-to-handle liquids need a pump that won't leak, wear out early, or fight against the chemical it's supposed to be pumping. The Iwaki MX-401CV7 solves that problem with a magnetic drive design that removes the mechanical shaft seal entirely, so there's no seal to wear down and no point where fluid can seep out over time.
Built with a glass fiber reinforced polypropylene casing and impeller, this pump end is made to stand up to aggressive chemicals without corroding or breaking down under regular use. Inside, a carbon bearing and alumina ceramic spindle keep things running smoothly, and the pump's self-radiating structure pushes pumped liquid around the bearing and spindle to carry heat away, which helps prevent warping and extends the life of internal parts even under demanding conditions.
This is a pump end only, so it pairs with a separately purchased 1-1/2 HP, 3450 RPM, 56C frame motor. That setup gives shops and facilities flexibility to match the pump with a motor they already have on hand or one that fits their specific power requirements, making it a practical option for chemical recirculation, filtration, plating, spraying, and similar process work across a range of industries — not just marine or industrial chemical plants, but also general manufacturing, laboratory setups, and equipment cooling applications.

Frequently Asked Questions
Q: Does the Iwaki MX-401CV7 include a motor?
A: No, this is a pump end only. It requires a separately purchased 1-1/2 HP, 3450 RPM, 56C frame motor to operate.
Q: Can this pump run dry without damage?
A: It can tolerate brief periods of dry running thanks to its carbon bearing, but extended dry running will still cause seizure and premature wear, so the pump should always be primed with liquid before use.
Q: What kinds of liquids can this pump handle?
A: It's designed for chemical recirculation and similar process liquids, but it cannot handle liquids containing slurry or heavy particulates.
Q: Is this pump self-priming?
A: No, the MX-401CV7 is not self-priming and must be primed with the liquid to be pumped before startup.
Q: How does the magnetic drive design improve reliability?
A: By removing the traditional shaft seal, the magnetic drive design eliminates a common leak and wear point, while its internal structure controls magnet movement to reduce friction and heat during operation.
