Iwaki L-MD-10 Liquid End: A Sealless Wet End Built for Dependable Fluid Handling
The Iwaki L-MD-10 is the liquid end, or wet end, for the compact MD-10 magnetic drive pump. Instead of buying a full pump and motor assembly, this part lets you replace just the fluid-contact section, which is the piece that actually wears out from years of continuous transfer duty. Built from glass-fiber reinforced polypropylene, it resists a wide range of chemicals and won't corrode the way metal housings do over time, making it a smart choice anywhere fluid purity or chemical exposure is a concern.
What sets this liquid end apart is the sealless magnetic drive design at its core. Rather than relying on a mechanical shaft seal that eventually leaks or wears out, magnetic force spins the impeller from outside the sealed chamber. That means no packing to replace, no seal failures to worry about, and a lot less maintenance over the life of the pump. A fixed ceramic spindle supports smooth, low-friction rotation, helping the unit run quietly and consistently even under regular use.
This part fits naturally into small-scale industrial, laboratory, and process environments where a compact, low-maintenance pump end is needed. Because it's non-metallic and chemically resistant, it works well beyond typical water transfer jobs. It suits everything from laboratory fluid handling and equipment cooling loops to chemical dosing setups and general recirculation tasks, giving facilities a reliable, budget-friendly way to keep an existing MD-10 pump running without replacing the entire unit.

FAQ Section
Q: Does the L-MD-10 include a motor?
A: No. This is the liquid end only, designed to attach to a compatible Iwaki MD-10 mag-drive motor assembly. It's intended for users replacing just the wet end of an existing pump.
Q: What liquids is this liquid end compatible with?
A: Thanks to its GFRPP construction, it handles a broad range of chemically aggressive and corrosive fluids, along with general process water, within its rated temperature and viscosity limits.
Q: Why choose a sealless magnetic drive design over a traditional seal pump?
A: A sealless design removes the mechanical shaft seal entirely, which eliminates a common failure and leak point. This means less maintenance, longer service intervals, and safer handling of aggressive liquids.
Q: Can this liquid end be used for non-marine applications?
A: Yes. While mag-drive pumps are popular in aquatic settings, this liquid end is equally suited to laboratory, chemical processing, cooling, and general industrial transfer applications.
Q: How do I know if the L-MD-10 is the correct replacement for my pump?
A: Confirm your existing unit is an Iwaki MD-10 series mag-drive pump before ordering, since liquid ends are matched to specific motor and pump size combinations.
