Iwaki MX-251CV6 Mag-Drive Pump End, 1x1 Poly, 56C Frame, Less Motor
The Iwaki MX-251CV6 is a rugged, seal-less magnetic drive pump end built for facilities that need reliable chemical transfer without the maintenance headaches of a traditional shaft seal. Its glass-fiber reinforced polypropylene casing and impeller stand up to a wide range of aggressive fluids, while the alumina ceramic liner ring and spindle add long-term wear resistance in demanding transfer applications. Because the magnetic coupling eliminates the seal entirely, there's no leak path to worry about, which makes this pump end a smart choice anywhere operators want cleaner, safer handling of corrosive or hazardous liquids.
This model ships as a pump end only, so it pairs with a standard 56C frame motor the customer already owns or plans to source separately, giving plenty of flexibility on horsepower and enclosure type. With 1" NPT suction and 1" NPT discharge connections, it handles flows up to 40 GPM and heads up to 75 feet, which covers a lot of ground for chemical recirculation, transfer, and scrubber-feed duty. The carbon bearing design also tolerates brief periods of dry running, adding a layer of forgiveness that operators appreciate when suction conditions aren't perfect.
Whether it's replacing a worn-out pump end or going into a new installation, the MX-251CV6 fits naturally into industrial and commercial systems where corrosion resistance, low maintenance, and dependable performance matter more than anything else. Its compact footprint and standardized mounting make it straightforward to install, and its proven mag-drive construction means fewer surprises down the road.
