March Pump's industrial TE-7S-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 53 gallons per minute at 10 feet, and its maximum head is 57.5 Feet (or around 25PSI). The standard wet end (the materials that come into contact with the solution) is composed of 316 Stainless Steel, Viton, Carbon, and Ceramic. The inlet connection is 1-1/2 inch female pipe thread, and the outlet is 1 inch male pipe thread.   There are two standard motors.  The first is a 1 Phase 60 hertz 115/208/230V and 50 hertz 110/220V 1 horsepower totally enclosed fan cooled motor.  The second is a 3 Phase 60 hertz 208/230/460V and 50 hertz 190/380V 1 horsepower totally enclosed fan cooled motor.  There are performance differences between the hertz options.  The maximum internal pressure the pump can tolerate is 200PSI, and the maximum liquid temperature is 250 Fahrenheit or 121 Celsius. The March TE-7S-MD centrifugal magnetic drive pump is capable of handling mildly or highly corrosive chemicals, acids, and solvents. To determine if the March TE-7S-MD is suitable for your application, please contact March Pump.

Perfect for Applications Including 

Applications for the TE-7S-MD Magnetic Drive Pump include chemical recirculation, chemical transfer, refrigerators, scrubber systems, detergent mixers, computer cooling, carbon arc furnace cooling, silver recovery systems, and marine air conditioners.
