Iwaki L-MD-15R Magnetic Drive Liquid End: A Reliable Replacement for MD & WMD Series Pumps
Keeping a magnetic drive pump running smoothly often comes down to having the right liquid end on hand, and the Iwaki L-MD-15R is built to make that replacement simple. This liquid end assembly includes everything needed to restore the wet-end performance of an Iwaki MD-15R or WMD series pump, from the front and rear casings to the impeller and O-ring seal. Because it's a genuine Iwaki component, it's engineered to the same tight tolerances as the original pump, so fit, flow, and sealing performance stay consistent after installation.
The GFRPP (glass-filled polypropylene) construction gives this liquid end strong resistance to a wide range of chemicals, acids, and corrosive fluids, making it a practical choice well beyond typical water transfer applications. Facilities running chemical dosing systems, industrial process lines, water treatment equipment, or laboratory fluid handling setups all benefit from a liquid end that won't degrade under repeated exposure to aggressive media. Its sealless magnetic drive design also means there's no mechanical shaft seal to wear out or leak, which reduces maintenance headaches over time.
Whether the goal is routine preventive maintenance or repairing a pump that's showing signs of wear, this liquid end offers a straightforward way to extend the service life of an existing Iwaki pump without replacing the entire unit. It's a cost-effective solution for facilities that want to keep spare parts on hand and minimize downtime when a rebuild is needed.

Frequently Asked Questions
Q: Does the L-MD-15R liquid end include the motor or drive unit?
A: No. This part is the liquid end only, consisting of the front casing, rear casing, impeller, and O-ring. The motor and magnetic drive coupling are separate components.
Q: Can this liquid end be used on both MD and WMD pump models?
A: Yes, the L-MD-15R liquid end is designed to be compatible with both the MD-15R and WMD-15R series pumps.
Q: What kind of liquids is the GFRPP material suitable for?
A: GFRPP offers strong resistance to many acids, chemicals, and corrosive fluids, making it suitable for chemical dosing, water treatment, and general industrial fluid transfer applications.
Q: Is any additional hardware needed to install this liquid end?
A: Installation typically uses the existing mounting hardware from the original pump assembly. No special tools beyond standard wrenches are generally required.
Q: How do I know if my pump needs a liquid end replacement instead of a full pump replacement?
A: If the pump motor and magnetic drive still function properly but you're seeing wear, cracking, or reduced flow performance from the wet end, replacing just the liquid end is usually a more economical option than replacing the entire pump.
