Iwaki MD-10L-115 Mag Drive Centrifugal Pump
The Iwaki MD-10L-115 is a compact magnetic drive centrifugal pump built for reliable, low-maintenance fluid transfer in equipment where space and quiet operation matter. Its glass-fiber reinforced polypropylene housing resists a wide range of chemicals, while the magnetically coupled design eliminates the shaft seal entirely, removing one of the most common points of pump failure. With a 1/125 HP shaded pole motor running on standard 115 volt power, this pump delivers smooth, dependable flow without drawing excessive current or generating much noise, making it a practical fit for lab benches, equipment enclosures, and OEM machine builds.
Inside, the pump relies on a PTFE bearing paired with an alumina ceramic thrust ring and spindle, a combination chosen for long service life even under continuous duty. An internal cooling circuit helps manage bearing temperature during operation, and the twin bearing system is designed to absorb thrust loads so the pump keeps running smoothly over time. Because it has so few moving parts, routine maintenance stays simple and infrequent compared to seal-based pump designs.
This is not a pump limited to any single industry. It shows up in laser systems, chiller loops, blood analyzers, water treatment skids, aquaculture systems, and general chemical circulation setups wherever a small, quiet, corrosion-resistant pump is needed. The 1/2 inch hose barb ports make plumbing straightforward, and the compact footprint means it can be integrated into tight equipment enclosures without a major redesign. Note that this pump is not self-priming, so it should always be installed with liquid present at startup to avoid running it dry.

Frequently Asked Questions
Q: Can the Iwaki MD-10L-115 run dry without damage?
A: No, this pump is not self-priming and should not be run dry, as doing so can damage the internal bearing and spindle components.
Q: What kind of fluids is this pump suitable for?
A: Its polypropylene construction handles a wide range of mild to moderately corrosive fluids, provided the fluid's specific gravity does not exceed 1.1.
Q: Does this pump require a mechanical seal?
A: No, the magnetic drive design eliminates the need for a shaft seal, which reduces the risk of leaks and lowers long-term maintenance needs.
Q: Is this pump suitable for continuous duty use?
A: Yes, the twin bearing system and internal cooling circuit are designed to support continuous operation while managing bearing temperature.
Q: What voltage and power does the MD-10L-115 require?
A: It operates on 115 Volts AC, single phase, 50/60 Hz, and uses a 1/125 HP shaded pole motor.
