Iwaki L-MX-400RV7 Liquid End Only – Mag-Drive Pump Head Replacement
If you're running an Iwaki MX-400 series magnetic drive pump and the motor is still going strong but the wet end has seen better days, the L-MX-400RV7 liquid end gives you a straightforward way to bring the pump back to full performance without replacing the whole unit. This liquid end only configuration includes the pump casing, impeller, and wetted components engineered specifically for the MX-400 platform, built from polypropylene with Viton sealing material to stand up to a wide range of chemicals, water treatment fluids, and industrial process liquids.
Because it's a seal-less magnetic drive design, there's no mechanical shaft seal to wear out or leak over time, which means less maintenance and fewer chances of fluid escaping into the surrounding environment. This makes the L-MX-400RV7 a practical choice for facilities handling aggressive or hazardous chemicals where leak prevention matters just as much as flow performance. Whether it's part of a chemical dosing system, a cooling loop, or a general fluid transfer application, this liquid end restores the pump's original hydraulic capability while keeping downtime to a minimum.
Swapping in a new liquid end instead of buying a complete pump also makes sense from a cost and sustainability standpoint. It lets you keep your existing motor and baseplate in service, cuts down on unnecessary equipment turnover, and gets your system back online faster since installation is typically a bolt-up replacement rather than a full re-plumb.

Frequently Asked Questions
Q: Does the L-MX-400RV7 include the motor?
A: No, this is a liquid end only, meaning it includes the pump casing, impeller, and wetted components but not the motor. It's designed to pair with your existing MX-400 series motor.
Q: What chemicals is this liquid end compatible with?
A: The polypropylene and Viton construction offers broad chemical resistance, but compatibility depends on the specific fluid, concentration, and temperature. It's best to confirm with a chemical compatibility chart before installation.
Q: Can I install this liquid end myself?
A: Yes, most users can install it with basic tools since it's designed as a bolt-up replacement onto the existing MX-400 motor and baseplate, though following the manufacturer's installation guide is recommended.
Q: Why choose a liquid end replacement instead of a full pump?
A: If your motor and baseplate are still functioning well, replacing just the liquid end saves money and reduces downtime compared to purchasing an entirely new pump.
Q: Is this liquid end suitable for continuous duty operation?
A: Yes, the MX-400 series liquid end is built for continuous industrial and process applications, though actual duty cycle depends on the specific fluid and operating conditions.
