Iwaki MXM-5431CFAH Magnetic Drive Chemical Process Pump (Less Motor)
Handling aggressive chemicals safely comes down to one thing: keeping the liquid completely sealed away from the outside world. That's exactly what the Iwaki MXM-5431CFAH is built for. Instead of relying on a mechanical shaft seal that can wear out and leak, this pump uses a magnetic coupling to drive the impeller, so there's no seal to fail and no fluid path to the atmosphere. The CFR-ETFE casing gives it strong resistance to a wide range of corrosive chemicals, while the high-density carbon bearing lets it tolerate brief dry-run conditions without immediately suffering damage — something that matters a lot when suction lines occasionally lose prime.
This is a pump end only, supplied less motor, and designed to mount on a standard NEMA 182TC frame motor. That makes it a practical option for facilities that already have a compatible motor on hand or that want to standardize their spare motor inventory across multiple pumps. With a 2 inch suction and 1-1/2 inch discharge, both on 150# ANSI flanged connections, it fits cleanly into typical process piping without needing custom adapters. The alumina ceramic liner ring and spindle add further wear resistance in demanding duty cycles, and the Aflas O-rings extend chemical compatibility into higher-temperature applications.
Facilities running chemical transfer, blending, plating lines, surface treatment, or general corrosive-fluid circulation will find this pump suited to continuous industrial use, not just occasional transfer duty. Because the motor is sold separately, buyers get the flexibility to pair it with the exact horsepower, voltage, and enclosure type their operation already standardizes on, while still getting Iwaki's sealless magnetic drive reliability at the pump end itself.

Frequently Asked Questions
Q: Does the MXM-5431CFAH include a motor?
A: No, this model is supplied as a pump end only. It requires a separately purchased motor built on a NEMA 182TC frame.
Q: What kinds of chemicals is this pump suitable for?
A: The CFR-ETFE casing and Aflas O-rings give it resistance to a wide range of corrosive fluids, including bleach and sulfuric acid, making it a common choice for chemical transfer and surface treatment lines.
Q: Can this pump handle brief loss of suction without damage?
A: The high-density carbon bearing is designed to tolerate short periods of dry running better than a standard bearing, though sustained dry running should still be avoided.
Q: What port connections does this pump use?
A: It has a 2 inch suction and 1-1/2 inch discharge, both configured as 150# ANSI flanged connections.
Q: Is this pump only used in marine or water-related settings?
A: No. While it can handle water-based fluids, it's primarily selected for industrial chemical process work such as blending, plating, etching, and corrosive chemical transfer across many non-marine industries.
