March Pump's industrial 1U-MD is an American submersible seal-less centrifugal magnetic drive pump. It is capable of generating a maximum flow of 2.3 gallons per minute at 0.25 feet, and its maximum head is 4.5 Feet (or around 2PSI).  The 1U-MD pump must be used submerged. The standard wet end (the materials that come into contact with the solution) is composed of Polypropylene, Buna N, Nylon, Carbon/Teflon, Stainless Steel, Cycolac, Delrin, and Ceramic Magnet.  When submerged, Epoxy, Noryl, Cycolac, Delrin, and the SJT Cord are also in contact with the solution. The inlet connection is a screen, and the outlet is 1/4 inch male pipe thread. The standard motor is a 1 Phase 115V or 230V 0.005 Horsepower motor, which can be run on either 50 or 60 hertz (there are performance differences between the hertz options).  The maximum internal pressure the pump can tolerate is 50PSI, and the maximum liquid temperature is 190 Fahrenheit or 160 Celsius in open air, or 87 Fahrenheit or 71 Celsius if submerged. The March 1U-MD centrifugal magnetic drive pump is capable of handling fresh water, salt water, and mild chemicals. To determine if the March 1U-MD is suitable for your application, please contact March Pump.
