March Pump's industrial BC-4K-MD is an American seal-less centrifugal magnetic drive pump ideal for applications such as chemical recirculation, chemical transfer, and scrubber systems. It is capable of generating a maximum flow of 14 gallons per minute at 1 feet, and its maximum head is 21.5 Feet (or around 9PSI). The standard wet end (the materials that come into contact with the solution) is composed of carbon filled Kynar (PVDF), Viton, and Ceramic. The inlet connection is 1 inch female pipe thread, and the outlet is 1/2 inch male pipe thread. The standard motor is a 1 Phase 115V or 230V 0.1 Horsepower blast cooled 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 75PSI, and the maximum liquid temperature is 200 Fahrenheit or 93 Celsius. The March BC-4K-MD centrifugal magnetic drive pump is capable of handling mildly or highly corrosive chemicals, acids, and solvents.
