Manufacturer of seal-less magnetically coupled submersible & air cooled centrifugal pumps for a wide range of chemical, industrial & solar/hydronic applications. Broad range of pump construction materials to handle most any type of solution. Magnetic drive design eliminates the multitude of problems related to shaft seals, including leakage & power draining friction. Pumps have one moving part within the pump housing assembly that can wear. The impeller &/or brushing can be replaced using a wrench or screw driver.
March specializes in the design and manufacture of precision pumps for a wide range of OEM, chemical, industrial, hydronic and solar applications. Pumps for highly corrosive or mild chemicals, acids or solvents, condensate pumps, and metering pumps - most of them magnetic drive design. In order to maintain the highest quality control standards, March manufactures most of its pump components in house, including some fractional horsepower motors and all injection molded plastics. In chemical pumps, this means close control of materials in contact with solutions and better compatibility with corrosive solutions.
All pump parts are designed to meet or exceed potential job demands. In pumps for highly corrosive applications all components to be exposed to chemicals are either encapsulated or molded of appropriately resistant plastics. Metals are used where plastics are not compatible with the solution to be handled. These pumps are recommended for high acid concentrations, alkalis, solvents and high specific gravity solutions. UL recognized components are used throughout, and many models are UL listed.
High quality materials of construction are used throughout. Proven materials like Delrin® polypropylene, Viton®, Teflon®, Ryton®, Kynar®, stainless steel and Hastelloy® cover a broad range of applications. Consult your March engineer about the right materials of construction for your application.
