Iwaki MD-15R-100 Magnetic Drive Pump
The Iwaki MD-15R-100 is a compact, sealless magnetic drive pump built for anyone who needs dependable, leak-free fluid movement without the maintenance headaches of a traditional shaft-seal pump. Its GFRPP polypropylene wet end resists a wide range of chemicals and corrosive fluids, while the magnetic coupling design completely eliminates the mechanical seal — meaning no drips, no seal replacements, and far less downtime over the life of the pump. Paired with a 1/75 HP, 100 Volt AC motor, it's engineered to run quietly and efficiently in tight spaces where noise and heat matter.
This pump isn't limited to one industry. It shows up in laboratory equipment, medical and blood-analyzer devices, laser cooling loops, chiller systems, aquariums, small-scale chemical dosing setups, and general fluid recirculation or transfer applications. The twin-bearing rotating spindle design helps the pump handle thrust loads gracefully and extends service life, while an internal cooling circuit keeps bearing temperatures in check during continuous operation. With 1/2 inch hose barb port connections, it installs easily into most small process lines.
For OEM integrators and end users alike, the MD-15R-100 offers a rare combination: a small footprint, low power draw, and the reliability that comes from a proven magnetic drive platform. Whether it's circulating water in a compact system or transferring mild chemicals in a lab, this pump is built to run consistently with minimal upkeep.

Frequently Asked Questions
Q: Can the Iwaki MD-15R-100 handle corrosive or aggressive chemicals?
A: Its GFRPP polypropylene construction offers strong chemical resistance for many mild-to-moderately corrosive fluids, though liquids containing iron, nickel, or other magnetic particles should be avoided since the pump relies on magnetic coupling.
Q: Does this pump require regular seal maintenance?
A: No. Because it's a sealless magnetic drive design, there is no mechanical shaft seal to wear out or replace, which significantly reduces routine maintenance compared to standard centrifugal pumps.
Q: Is the MD-15R-100 self-priming?
A: No, this pump is not self-priming and should be installed with a flooded suction or primed before startup to avoid running dry, which can damage the internal components.
Q: What voltage and phase does this pump require?
A: The MD-15R-100 operates on 100 Volts AC, single phase power, drawing approximately 0.29 Amps during normal operation.
Q: Can this pump run dry for short periods?
A: No, running the pump dry — even briefly — can cause severe damage to the bearings and impeller, so it should always be operated with liquid present in the pump chamber.
