Iwaki MD-30R-115NL Magnetic Drive Centrifugal Pump
If you need a small pump that just keeps running without drama, the Iwaki MD-30R-115NL is worth a close look. It's a magnetically coupled centrifugal pump built from glass-fiber-reinforced polypropylene, so it shrugs off a wide range of chemicals and won't corrode the way a metal pump would over time. Because the impeller is driven magnetically rather than through a shaft seal, there's nothing to leak and very little to wear out, which is exactly why these pumps show up so often in labs, coolant loops, and process equipment where reliability matters more than raw power.
Powering the pump is a 1/16 HP, 115V single-phase TENV motor, quiet enough to sit right next to sensitive equipment without adding noise to the room. The 3/4 inch hose barb ports make plumbing straightforward, and the compact footprint means it fits into tight equipment enclosures where a bulkier pump simply wouldn't work. An internal cooling circuit also helps keep bearing temperatures in check during continuous duty, which extends the working life of the pump.
Whether it's circulating coolant through a laser system, moving fluid in a blood analyzer, or handling general chemical transfer and recirculation in a process line, the MD-30R-115NL is built to run continuously with minimal upkeep. It's a dependable, low-maintenance choice for anyone who wants a pump that does its job quietly in the background.

Frequently Asked Questions
Q: Is the Iwaki MD-30R-115NL self-priming?
A: No, this pump is not self-priming. It requires the pump housing to be filled with liquid before startup, and it should never be run dry, as this can damage the internal bearings.
Q: What liquids should be avoided with this pump?
A: Because the pump relies on magnetic coupling to drive the impeller, liquids containing iron, nickel, or other ferromagnetic particles should be avoided, as they can interfere with the magnetic coupling.
Q: Can this pump run continuously?
A: Yes, the MD-30R-115NL is designed for continuous duty. Its internal cooling circuit helps manage bearing temperature, allowing it to operate for extended periods without overheating.
Q: What is the difference between the MD-30R-115NL and the MD-30RT-115NL?
A: The MD-30R-115NL uses 3/4 inch hose barb port connections, while the MD-30RT-115NL uses 3/4 inch NPT threaded port connections. Both share the same 1/16 HP, 115V motor and pump body.
Q: Is this pump suitable for marine or raw water use?
A: While Iwaki magnetic drive pumps are used in some marine and raw water applications, the MD-30R-115NL is a general-purpose process pump commonly used in laboratory, medical, chiller, and industrial transfer applications, not exclusively marine settings.
