Iwaki MD-6-100 Magnetic Drive Pump – Polypropylene, 100V
When a process calls for a pump that simply won't leak, the Iwaki MD-6-100 earns its reputation. This compact magnetic drive centrifugal pump does away with the traditional shaft seal entirely, coupling the motor to the impeller through a magnetic field instead of a mechanical connection. That single design choice removes the most common failure point in small process pumps, making the MD-6-100 a dependable choice for labs, small-scale chemical transfer, and equipment builders who can't afford drips or downtime.
Built from GFRPP polypropylene, the pump body resists a wide range of acids, bases, and aggressive fluids that would corrode metal housings over time. It's powered by a close-coupled 1/250 horsepower, 100-volt single-phase motor, so it draws minimal power while still delivering enough flow for low-volume transfer and recirculation tasks. The 35/64-inch hose barb ports make plumbing straightforward, letting it drop into existing setups without special fittings or adapters.
Despite its small size, the MD-6-100 is engineered for the same reliability standards found across Iwaki's broader magnetic drive lineup. It runs quietly, handles fluids up to 80°C, and holds up under continuous duty in tight, equipment-dense environments. Whether it's moving water in an aquarium filtration system, circulating coolant in a small industrial machine, or transferring reagents in a laboratory, this pump is built to run reliably in the background without demanding constant attention.

Frequently Asked Questions
Q: Is the Iwaki MD-6-100 suitable for corrosive chemicals?
Its GFRPP polypropylene construction and seal-less magnetic drive design make it well suited for many acids, bases, and corrosive fluids, though fluid compatibility should always be checked against the specific chemical being used.
Q: Does this pump require regular maintenance?
Because it has no mechanical shaft seal, the MD-6-100 requires far less routine maintenance than traditional seal-based pumps, though periodic inspection of the impeller and bearings is still recommended for long-term reliability.
Q: Can the MD-6-100 run dry without damage?
Like most magnetic drive pumps, running dry for extended periods can damage the internal bearings, so it's best to ensure the pump stays primed during operation.
Q: What kind of power supply does this pump need?
It operates on a 100V AC single-phase power supply, making it compatible with standard low-voltage electrical setups common in labs and light industrial environments.
Q: How is the MD-6-100 different from larger Iwaki MD series pumps?
It sits at the lower end of the MD series lineup, offering a smaller footprint and lower flow output, making it ideal for compact applications where larger MD or WMD models would be oversized.
