MARINE EQUIPMENT IN MEXICO
A circulation pump must supply the flow an installation needs against the actual resistance of its circuit. PLC Marine helps compare March pumps for marine air-conditioning systems in Mexico, for new projects and replacements. Start with the existing pump nameplate, system information and piping route; choosing by motor power or physical size alone can lead to the wrong selection.
Explore the brandsThese three March references allow comparison of compact marine pumps and higher-capacity equipment. Detailed data, curves and dimensions are available on our March Pumps page. The photograph identifies an example model; the electrical version is confirmed by complete-pump part number.
A compact marine reference with a 3/4-inch FPT inlet and 1/2-inch MPT outlet. Separate single-phase 115 V and 230 V versions are available for 50/60 Hz. Check the curve for the operating frequency and identify the complete-pump part number.

Another marine circulation option, with a 1-inch FPT inlet and 1/2-inch MPT outlet. The 115 V and 230 V versions use different part numbers. Compare available flow at the required head, dimensions and connections before replacing equipment.

A higher-capacity alternative for projects whose flow and head requirements justify it. Single-phase and three-phase versions have different motor configurations; confirm voltage, frequency, phase and part number. It should not be selected simply because it is a larger pump.
View equipment and documentationThe duty point combines flow and pumping head. The manufacturer’s curve shows what a pump can deliver at that point; maximum catalogue figures do not promise the same flow in every installation.
Start with the flow required by the equipment manufacturer. Review elevation and losses through piping, elbows, strainers, valves and heat exchangers as applicable. If one pump serves several units, check flow in each branch and simultaneous operation. A headline litres-per-minute or gallons-per-hour rating does not replace this assessment.
Photograph the nameplate and confirm voltage, frequency and phase. Check diameters, threads, orientation, length and service space. A fitting that appears to match does not establish equivalence; a generic reference to 110 or 220 V is also no substitute for the exact motor rating.
The March circulation references shown here require review of flooded suction and their model-specific instructions. Consider the water intake, strainer, suction route and possible air pockets. Do not assume they self-prime or can run without liquid. Installation and final verification are the responsibility of the technician handling the system.
Do not assume so. Bilge pumping and continuous air-conditioning circulation are different applications. For air conditioning, confirm duty, materials, flow at the required head, electrical supply and the equipment manufacturer’s requirements. This page focuses on March circulation pumps, not bilge-system design.
BTU ratings describe thermal capacity, not the flow a pump will deliver through a particular circuit. Confirm the air conditioner’s required flow and check it against the pump curve and installation losses. An indicative catalogue BTU equivalence does not replace that assessment.
It is the end of the curve near zero flow. It does not mean the pump delivers maximum flow at that head. Compare available flow at the expected operating head, using the curve for the relevant frequency.
That depends on the model and motor. The LC-3M-MD and LC-5M-MD references shown have separate 115 V and 230 V part numbers and should not be treated as dual-voltage versions. Other models have different configurations. Always confirm the nameplate and part number.
Send the model and part number, a nameplate photograph, voltage, frequency, phase, connections and available dimensions. Include the equipment served, known circuit details, quantity and delivery location. If the existing unit is unidentified, photographs help start the review but do not establish a direct replacement.
