Perfect for Applications Including
The 320-AP-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 320-AP-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 320-AP-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 320-AP-MD. Chemical Resistance Chart (öffnet in neuem Tab)
March Pump’s industrial 320-AP-MD is an American seal-less centrifugal magnetic drive pump ideal for applications such as chemical recirculation and chemical transfer. It is capable of generating a maximum flow of 3.3 gallons per minute at 1 feet, and its maximum head is 40 Feet (17PSI). The standard wet end (the materials that come into contact with the solution) is composed of Polypropylene, Viton, and Ceramic. The inlet connection is 5/8 inch smooth, and the outlet is 1/2 inch smooth. The standard motor is a 1 Phase 115V or 230V 0.083 Horsepower 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 320-AP-MD centrifugal magnetic drive pump is capable of handling mildly or highly corrosive chemicals, acids, and solvents. To determine if the March 320-AP-MD is suitable for your application, please contact March Pump.
