Summary Paragraph

March Pump’s industrial LC-3M-MD is an American submersible seal-less centrifugal magnetic drive pump. It is capable of generating a maximum flow of 8.5 gallons per minute at 4 feet, and its maximum head is 19 Feet (8PSI).  It is capable of 24,000 BTU a hour.  The LC-3M-MD pump may be used submerged or not submerged. The standard wet end (the materials that come into contact with the solution) is composed of Polypropylene, Buna N, Cupric Nickel, Carbon, Ceramic, and Ceramic Magnet.  When submerged, Epoxy, Stainless Steel, Polysulfone, and the Cord are also in contact with the solution. The inlet connection is 3/4 inch female pipe thread, and the outlet is 1/2 inch male pipe thread. The standard motor is a 1 Phase 115V or 230V 0.05 Horsepower 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 25PSI, and the maximum liquid temperature is 130 Fahrenheit or 54 Celsius.

The pump is Ignition Protected per SAE J1171 and ISO 8846.  The impeller has a carbon bushing allowing the pump to run dry longer before suffering damage.
