Iwaki MD-100RT-220 Magnetic Drive Pump, Polypropylene, 1" NPT, 220V
The Iwaki MD-100RT-220 is a seal-less magnetic drive centrifugal pump built for anyone who needs dependable fluid transfer without the maintenance headaches of traditional shaft-seal pumps. Because the motor and pump chamber are magnetically coupled rather than mechanically linked, there's no seal to wear out, leak, or replace over time. The glass-fiber reinforced polypropylene housing stands up well to a wide range of corrosive and aggressive liquids, making this pump a practical choice across chemical processing, laboratory, industrial, and general fluid-handling setups where a durable, low-maintenance solution matters.
Paired with a 1/3 HP, 220V single-phase TEFC motor, the MD-100RT-220 runs quietly while still delivering solid performance for its size, moving fluid at up to roughly 35.6 GPM at zero pressure with a maximum head of about 39 feet. Its twin bearing system, PTFE bearing surfaces, and ceramic thrust ring are engineered to handle thrust loads and reduce internal wear, which helps the pump hold up under continuous or repeat-cycle use. The 1" NPT threaded inlet and outlet ports make it straightforward to integrate into existing piping without needing special adapters.
This pump fits naturally into OEM equipment, recirculation loops, chemical transfer lines, laser and chiller cooling systems, and other process applications where a compact, non-metallic, magnetically driven pump is preferred over a traditional metal or seal-based unit. It's not self-priming, so it should be installed below the fluid source, but once set up correctly it offers a quiet, efficient, and long-lasting way to keep fluid moving.

Frequently Asked Questions
Q: Is the Iwaki MD-100RT-220 self-priming?
A: No, this pump is not self-priming. It should be installed at a level lower than the fluid source, ideally at least 12 inches below the liquid level, to ensure proper priming and avoid air entering the pump.
Q: What types of liquids can the MD-100RT-220 handle?
A: It's well suited for water-based and many chemically aggressive fluids compatible with polypropylene. It should not be used with liquids that significantly swell polypropylene, such as certain paraffinic or halogenated hydrocarbons.
Q: Can the MD-100RT-220 run continuously?
A: Yes, its twin bearing system and cooling circuit are designed to support continuous-duty operation in appropriate applications, though actual run life depends on the fluid handled and operating conditions.
Q: Does this pump require routine maintenance?
A: Because it uses a seal-less magnetic drive design, there's no mechanical shaft seal to maintain or replace, which significantly reduces routine maintenance compared to traditional centrifugal pumps.
Q: What power supply does the MD-100RT-220 require?
A: It operates on 220V AC, single-phase power, and should never be run at a voltage other than what's specified on the motor nameplate.
