Iwaki MD-15R-230GS Magnetic Drive Pump
The Iwaki MD-15R-230GS is a compact magnetic drive centrifugal pump built for anyone who needs to move liquids without worrying about leaks, seal wear, or constant maintenance. Its GFRPP polypropylene body and impeller stand up well to a wide range of fluids, and because the pump uses magnetic coupling instead of a mechanical shaft seal, there's nothing to wear out or drip over time. The close-coupled 1/75 HP, 230V single-phase motor keeps the whole unit small and quiet, making it easy to tuck into tight equipment layouts or benchtop setups.
What sets this pump apart is how little attention it needs once it's running. A twin bearing system absorbs thrust loads and extends service life, while the hollow rotating design creates an internal cooling circuit that keeps bearing temperatures down during continuous operation. With 1/2 inch hose barb ports on both the inlet and outlet, it's straightforward to plumb into an existing system, and the few moving parts inside mean less to inspect and replace down the road.
Because it's built with corrosion-resistant materials and a sealed magnetic drive, the MD-15R-230GS fits comfortably into chemical handling, industrial process, laboratory, and general liquid transfer applications, not just aquatic or marine setups. It's a practical choice whenever a small, dependable, low-maintenance pump is needed to circulate or transfer liquid reliably day after day.

Frequently Asked Questions
Q: Is the Iwaki MD-15R-230GS suitable for chemical fluids or only water?
Its GFRPP polypropylene construction and seal-less magnetic drive make it suitable for many chemical and corrosive liquids in addition to water, though compatibility should always be checked against the specific fluid.
Q: Does this pump require priming before use?
Like most centrifugal pumps, it performs best when the intake line is flooded or primed, since centrifugal designs are not self-priming.
Q: Can the MD-15R-230GS run dry without damage?
Running the pump dry for extended periods can damage the internal bearings and should be avoided; the internal cooling circuit relies on the pumped fluid for lubrication and heat dissipation.
Q: What replaces the older MD-15R-220 model?
The MD-15R-220 catalog number has been updated by the manufacturer and now ships as the MD-15R-230GS.
Q: Is this pump only used in marine or aquatic settings?
No, while it performs well in aquatic environments, it is equally suited to industrial, chemical processing, laboratory, and general liquid transfer applications.
