Perfect for Applications Including

The 335-CP-MD has the durability for continuous duty in applications requiring low flow and high head. Typical applications include laser cooling, medical systems, filter systems, and various processing equipment in the electronics industry.

Great for Chemicals Including

The 335-CP-MD has pumped Acetic Acid, Citric Acid, Ethylene Glycol, Formaldehyde, Hydrochloric Acid (Muriatic), Nitric Acid, Phosphoric Acid, Potassium Chloride, Potassium Hydroxide, Sodium Hydroxide (Caustic Soda), Sodium Chloride, Sulfuric Acid, Fresh Water, Salt Water, DI Water, and many more chemicals. The 335-CP-MD may have been modified to handle these chemicals. This pump may have to be modified to pump specific gravities, viscosities, or elevated temperatures different then ambient water. Please contact March Pump to review your application before using the 335-CP-MD. Chemical Resistance Chart

Summary Paragraph

March Pump’s industrial 335-CP-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 12 gallons per minute at 1 foot, and its maximum head is 68 Feet (29PSI). The standard wet end (the materials that come into contact with the solution) is composed of Polypropylene, Viton, and Ceramic. The inlet connection is 3/4 inch male pipe thread, and the outlet is 3/4 inch male pipe thread. The standard motor is a 1 Phase 115/230V or 3 Phase 230/460V 0.33 Horsepower totally enclosed fan 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 50PSI, and the maximum liquid temperature is 190 Fahrenheit or 87 Celsius. The March 335-CP-MD centrifugal magnetic drive pump is capable of handling mildly or highly corrosive chemicals, acids, and solvents. To determine if the March 335-CP-MD is suitable for your application, please contact March Pump.
