Iwaki MD-15RT-115NL Poly Magnetic Drive Pump
The Iwaki MD-15RT-115NL is a compact, seal-less magnetic drive centrifugal pump built for anyone who needs dependable fluid handling without the maintenance headaches of a traditional shaft-seal design. Instead of relying on mechanical seals that wear out and leak over time, this pump uses magnetic coupling to transfer power from the motor to the impeller, which means fewer moving parts, less friction, and a quieter, cooler-running unit that holds up well over years of regular use.
Constructed from glass fiber reinforced polypropylene (GFRPP), the pump resists corrosion from a wide range of aggressive chemicals and is equally at home in saltwater environments. A rotating ceramic spindle paired with PTFE bearings and a ceramic thrust ring keeps wear to a minimum, while the twin bearing system helps the pump handle thrust loads and extend its working life. Its 1/75 HP, 115V motor is paired with 1/2" NPT threaded ports, making it easy to drop into existing plumbing for process transfer, recirculation, or general fluid movement tasks.
Whether the application is industrial process fluid handling, laboratory equipment, aquaculture systems, or any setup that demands a corrosion-resistant, low-maintenance pump, the MD-15RT-115NL delivers steady performance in a small, efficient package. Built-in thermal protection with automatic restart adds an extra layer of reliability, so operators can count on consistent operation without constant oversight.

Frequently Asked Questions
Q: Can the Iwaki MD-15RT-115NL run dry without damage?
A: No, this pump is not self-priming and should not be operated dry, as running it without liquid can damage internal components.
Q: Is this pump suitable for saltwater applications?
A: Yes, the GFRPP construction and ceramic bearing materials make it compatible with saltwater and other corrosive fluids.
Q: What kind of liquids should be avoided with this pump?
A: Liquids containing iron, nickel, or other magnetic materials should be avoided, since the pump relies on magnetic coupling to operate.
Q: Does the pump require regular maintenance like traditional seal pumps?
A: No, the seal-less magnetic drive design significantly reduces maintenance needs since there are no mechanical shaft seals to wear out or replace.
Q: What voltage and horsepower does this pump use?
A: The MD-15RT-115NL runs on a 115V AC, 1-phase motor rated at 1/75 HP.
