Iwaki MD-70RLZT-220 Pump – 3/4" High Pressure Magnetic Drive Pump
The Iwaki MD-70RLZT-220 is a compact, high pressure magnetic drive pump built for demanding fluid transfer tasks where reliability and corrosion resistance matter. Manufactured in Japan, this seal-less centrifugal pump uses a magnetic coupling design that eliminates the need for mechanical shaft seals, reducing leak points and maintenance requirements while keeping operation quiet and energy efficient. Its rugged polypropylene construction makes it well suited for handling aggressive chemicals, high purity fluids, and general water transfer alike.
With a 2/7 HP motor running at 220 volts, this pump delivers strong performance for its size, moving up to 684 gallons per hour with a maximum head of roughly 66 feet. The 3/4" threaded inlet and outlet ports make plumbing straightforward for a wide range of setups, from laboratory and semiconductor equipment to industrial process lines and OEM machinery. Because it is engineered for high pressure applications, it holds up well in systems that need consistent flow under load.
Beyond industrial and chemical process use, the MD-70RLZT-220 has also earned a strong reputation in aquarium and water feature applications, where its quiet operation and durable, low-heat design are valued for long-term reliability. Whether the application is a laser cooling system, a blood analyzer, a chemical injection process, or a high-performance aquarium setup, this pump offers a dependable, low-maintenance solution built to last.
