Iwaki MD-6L-115 Polypropylene Magnetic Drive Pump
Small businesses and labs that move corrosive or sensitive fluids often struggle to find a pump that's both compact and dependable without breaking the budget. The Iwaki MD-6L-115 solves that problem with a sealless magnetic drive design built from GFRPP polypropylene, giving it strong resistance to chemical attack while eliminating the leak points common in shaft-seal pumps. Its 1/2" hose barb connections and 1/250 HP, 115V motor make it easy to drop into existing setups without heavy rework.
This pump is well suited for low-flow transfer and recirculation tasks where reliability matters more than raw horsepower. Because the magnetic coupling isolates the motor from the fluid path entirely, there's no seal to wear out and no risk of fluid leaking into the motor housing. That makes the MD-6L-115 a practical choice for chemical processing, water treatment, laboratory equipment, and even non-marine industrial applications like chillers, lasers, and blood analyzers, anywhere a quiet, compact, corrosion-resistant pump is needed.
Owners also appreciate how little maintenance this pump demands. With no mechanical seal to replace and a simple, rugged construction, the MD-6L-115 is designed to run for long stretches with minimal attention, as long as it's installed correctly and never run dry. It's a dependable, budget-friendly option for anyone who needs steady, leak-free fluid movement in a small footprint.

FAQ Section
Q: Can the Iwaki MD-6L-115 run dry without damage?
A: No, this pump is not self-priming and should never be run dry, since doing so can damage the internal bearings and shorten the pump's service life.
Q: What types of fluids is the MD-6L-115 compatible with?
A: Its GFRPP polypropylene construction makes it well suited for many corrosive and chemical fluids, though it should not be used with liquids that swell polypropylene, such as certain hydrocarbons and halogenated solvents.
Q: Does this pump require a mechanical seal replacement over time?
A: No, the magnetic drive design is sealless, so there's no shaft seal to wear out or replace, which reduces long-term maintenance needs.
Q: Is the MD-6L-115 suitable for continuous operation?
A: Yes, when installed properly with adequate suction head and never run dry, it's designed for reliable, long-term continuous or intermittent duty in light industrial and lab settings.
Q: How should the pump be positioned relative to the liquid source?
A: It should be installed lower than the liquid level of the suction tank, ideally by at least 12 inches, to prevent air from entering the pump and causing damage.
