Iwaki L-MD-70RT Liquid End Mag-Drive Pumphead
When a mag-drive pump starts losing pressure or shows signs of wear at the casing or impeller, replacing the entire unit isn't always necessary. The Iwaki L-MD-70RT liquid end is a standalone replacement pumphead built specifically for MD and WMD series mag-drive pumps, letting you restore full performance without swapping out the motor. Made from GFRPP polypropylene, it's designed to resist the kind of chemical exposure that breaks down lesser materials over time, making it a practical choice for process and transfer applications where corrosion resistance actually matters.
Because this is a seal-less, magnetically driven design, there's no mechanical shaft seal to fail or leak, which cuts down on the maintenance headaches that come with traditional centrifugal pumps. The twin bearing system spreads out thrust loads to help extend service life, while the hollow rotating design keeps bearing temperatures in check during continuous operation. With 1 inch NPT threaded port connections, it's built to drop into existing MD-70RT and compatible pump assemblies with minimal fuss, giving facilities a straightforward path to getting equipment back online.

FAQs
Q: Is the Iwaki L-MD-70RT a complete pump or just the wet end?
It's the liquid end (pumphead) only, meaning it includes the casing, impeller, and related wet components but not the motor. It's designed to pair with an existing compatible motor assembly.
Q: What pumps is the L-MD-70RT compatible with?
It's built for Iwaki's MD and WMD mag-drive series, including models like the MD-70RLT-115 and MD-70RT-220 pump and motor assemblies.
Q: Why choose a mag-drive liquid end over a standard sealed pump?
Magnetic drive designs remove the mechanical shaft seal entirely, which reduces the risk of leaks and lowers long-term maintenance needs, especially in corrosive or continuous-duty applications.
Q: What materials make contact with the fluid being pumped?
The wetted components, including the casing and impeller, are made of GFRPP polypropylene, chosen for its resistance to a wide range of chemicals.
Q: Can this liquid end handle continuous-duty operation?
Yes, the twin bearing system and internal cooling circuit are designed to manage thrust loads and heat buildup, supporting reliable use in continuous or heavy-duty service.
