Iwaki MD-30R-220 Magnetic Drive Pump
The Iwaki MD-30R-220 is a compact sealless magnetic drive centrifugal pump built for reliable, low-maintenance liquid transfer. Instead of relying on a traditional mechanical shaft seal, the pump uses a magnetically coupled impeller housed inside a fully enclosed GFRPP polypropylene casing, which means there's no shaft penetration through the pump chamber and virtually no risk of seal-related leaks. This design makes it a popular choice anywhere aggressive, corrosive, or hard-to-contain fluids need to move safely from one point to another, whether that's in a lab, a treatment system, or a manufacturing line.
Powered by a 1/16 HP, 220V AC, single-phase TENV (totally enclosed, non-ventilated) motor, the MD-30R-220 is engineered to run cool, quiet, and consistently even in demanding duty cycles. Its 3/4 inch hose barb ports make plumbing straightforward, and the all-plastic wetted construction resists a wide range of chemicals that would corrode metal pump components over time. Operators appreciate that the unit is compact enough to fit into tight equipment layouts while still delivering dependable flow performance.
This pump isn't limited to any single industry. It's equally at home in chemical processing, water treatment, plating operations, laboratory equipment, and general industrial fluid handling — anywhere a small, sealless, corrosion-resistant pump is needed. If reliability, chemical compatibility, and a maintenance-friendly design matter for your application, the MD-30R-220 is a solid, field-proven option.

Frequently Asked Questions
Q: Can the Iwaki MD-30R-220 run dry without damage?
A: No. Like most magnetic drive pumps, running it dry can cause overheating and damage to the bearing and spindle, so it should always be primed with liquid before operation.
Q: What kinds of chemicals is this pump compatible with?
A: Its GFRPP construction handles a wide range of acids, bases, and corrosive fluids, but exact compatibility depends on concentration and temperature, so checking a chemical compatibility chart before use is recommended.
Q: Does the MD-30R-220 require routine seal maintenance?
A: No, because the magnetic drive design has no mechanical shaft seal, there's nothing to wear out or replace in that regard, which significantly reduces routine maintenance needs.
Q: Can this pump be used for continuous duty applications?
A: Yes, the TENV motor and sealless design are well suited for continuous or long-cycle operation as long as the pump stays primed and operating temperatures stay within its rated range.
Q: Is the MD-30R-220 suitable for both indoor and light industrial installations?
A: Yes, it's compact enough for benchtop or small equipment integration while also being rugged enough for industrial process lines, making it versatile across many settings.
