Iwaki L-MD-100RT Reliable Liquid End for Your Iwaki Mag-Drive Pump
The Iwaki L-MD-100RT is a replacement liquid end designed for the MD-100RT and WMD-100RT series magnetic drive centrifugal pumps. Built from glass-fiber reinforced polypropylene (GFRPP), this pump head is engineered to resist corrosion from a wide range of chemicals and process fluids, making it a practical choice for anyone looking to restore or upgrade an existing pump without replacing the entire motor assembly.
Because it uses magnetic coupling instead of a traditional mechanical seal, this liquid end eliminates the common failure points associated with seal leaks, giving operators a cleaner, safer way to move liquids in tight or sensitive environments. The 1-inch NPT threaded ports make it straightforward to connect into existing plumbing, and the alumina ceramic bearing and spindle are built to hold up under continuous duty cycles.
While this style of pump end shows up often in laboratory, medical device, and light industrial cooling systems, it's just as suited to laser equipment, chiller loops, and general chemical transfer tasks. If your current MD or WMD-100 series pump has a cracked casing, worn impeller, or is simply due for a refresh, the L-MD-100RT liquid end offers a cost-effective way to bring it back into service.

Frequently Asked Questions
Q: Is the L-MD-100RT a complete pump or just the liquid end?
It's a replacement liquid end (pump head) only, designed to be mounted onto an existing motor bracket rather than sold with a motor.
Q: What motors is this liquid end compatible with?
It's built to pair with Iwaki MD-100RT and WMD-100RT series motor assemblies using the standard mounting configuration for that pump line.
Q: Can this pump end handle corrosive chemicals?
The GFRPP construction offers good resistance to many corrosive and aggressive fluids, though compatibility should be checked against the specific chemical being pumped.
Q: Does this pump head require a mechanical seal?
No, it uses magnetic drive coupling, which removes the need for a traditional mechanical shaft seal.
Q: What size fittings does the L-MD-100RT use?
It has 1-inch NPT threaded suction and discharge ports.
