Iwaki MX-400CV7 1.5" Magnetic Drive Pump End – Polypropylene
The Iwaki MX-400CV7 is a rugged, seal-less magnetic drive pump end built for demanding fluid transfer tasks where leak-free operation matters most. Constructed with a polypropylene housing, Viton seals, and a PTFE/alumina ceramic bushing, this pump is designed to handle a wide range of corrosive and non-corrosive liquids without the risk of shaft seal failure. Its non-contact magnetic coupling means there's nothing to wear out where the drive meets the wet end, which translates into fewer maintenance headaches and longer service life even in tough environments.
This pump end ships without a motor, giving buyers the flexibility to pair it with the drive they already have on hand or select one that matches their exact horsepower and voltage needs. With 1.5" ports and a best-efficiency point around 40 GPM at 29 feet of head, the MX-400CV7 fits nicely into small to mid-sized transfer systems, recirculation loops, and process lines. It's equally at home moving chemicals in an industrial setting, supporting filtration and washing processes, or handling fluid transfer duties on a boat or in a marine equipment room — the polypropylene construction and chemical-resistant wetted parts make it a versatile choice across applications, not just a marine-specific unit.
Owners appreciate that the MX-400CV7 is part of Iwaki's well-established MX series, a line known for its self-radiating structure that helps dissipate heat and tolerate brief dry-running or closed-valve conditions better than typical mag drive pumps. Whether you're replacing a worn-out pump end or specifying a new pump for a chemical transfer application, this model offers a dependable, budget-friendly option backed by a trusted manufacturer.

Frequently Asked Questions
Q: Does the Iwaki MX-400CV7 come with a motor included?
No, the MX-400CV7 is sold as a pump end only. You'll need to pair it with a NEMA-frame motor rated for 3/4HP that matches your application's voltage and mounting requirements.
Q: What kind of liquids can this pump handle?
Thanks to its polypropylene housing and Viton seals, the MX-400CV7 works well with a variety of chemicals including bleach and other corrosive fluids, as well as general industrial and marine fluids, though compatibility should always be checked against your specific chemical.
Q: Can this pump run dry for any period of time?
Brief dry-running is tolerated better than typical mag drive pumps thanks to the self-radiating structure, especially when equipped with the carbon bushing option, but sustained dry running is not recommended and can damage the bearing.
Q: Does the MX-400CV7 require flooded suction?
Yes, this model requires a flooded suction installation. If self-priming is needed, Iwaki's SMX series is designed for that purpose instead.
Q: Is this pump suitable for marine use?
Yes, the MX-400CV7 is commonly used in marine air conditioning and onboard fluid transfer systems, though it's equally suited to industrial chemical processing and general fluid handling applications outside of marine settings.
