Iwaki MD-6-230 Magnetic Drive Pump
The Iwaki MD-6-230 is a compact magnetic drive centrifugal pump built for anyone who needs to move aggressive or high-purity liquids without worrying about leaks or seal failure. Because the impeller is coupled to the motor magnetically rather than through a shaft seal, there's nothing for corrosive chemicals to wear through over time. The entire wetted pathway is made from glass fiber reinforced polypropylene (GFRPP), so it stands up well to a wide range of acids, bases, and solvents that would eat through metal components in a matter of weeks.
This pump was designed to be small, quiet, and easy to live with. It draws very little power for what it delivers, running on a 1/250 HP, 230 volt single-phase motor, and it fits into tight spaces where a bulkier pump simply wouldn't work. That makes it a popular choice not just in labs and chemical processing lines, but also in equipment like laser systems, chillers, and blood analyzers where quiet, dependable circulation matters as much as raw flow. With only a handful of moving parts, there's very little to maintain, and the sealless design means fewer surprises down the road.
Whether it's handling a corrosive chemical transfer, keeping a cooling loop circulating, or supporting a piece of analytical instrumentation, the MD-6-230 is built to run reliably in the background without demanding much attention. It's a straightforward, well-engineered solution for anyone who needs dependable fluid movement in a small footprint.

FAQs
Q: Can the Iwaki MD-6-230 handle corrosive chemicals?
A: Yes. Its GFRPP construction and sealless magnetic drive design make it well suited for aggressive chemicals that would damage metal pumps or standard shaft-seal pumps.
Q: Does the MD-6-230 require regular maintenance?
A: It's designed to be low-maintenance. Since there's no mechanical shaft seal to wear out, and it has very few moving parts, upkeep is minimal compared to traditional centrifugal pumps.
Q: Is this pump only used for marine or boating applications?
A: No. While it's sold through some marine suppliers, the MD-6-230 is primarily an industrial and laboratory pump, commonly used in chemical transfer, laser cooling, chillers, and analytical equipment.
Q: What is the maximum liquid temperature this pump can handle?
A: It's rated for liquids between 32°F and 176°F (0°C to 80°C), though the ideal range can vary depending on the specific fluid being pumped.
Q: What voltage does the MD-6-230 operate on?
A: It runs on 230 volts AC, single phase, and is built around a compact 1/250 HP capacitor-run induction motor.
